ARLP018 Propagation de K7RA

Solar activity made a healthy jump over the past week, with average

daily sunspot numbers up over 30 points to 120.9, and average daily

solar flux increasing over 27 points to 136.5.

The most active day for geomagnetic indices was May 1, when the

planetary A index reached 21 and the high-latitude college A index

(measured near Fairbanks, Alaska) was a whopping 57. That number has

been higher, but only twice in the past six months, when it was 64

on March 1 and 79 on March 17.

The latest forecast has solar flux at 155 on May 3-4, 150 on May

5-6, 145 on May 7-9, then 140, 125 and 120 on May 10-12, 125 on May

13-15, 120 on May 16-17, then 125, 120, and 130 on May 18-20, 135 on

May 21-22 and 130 on May 23-24.

Predicted planetary A index is 8 on May 3-4, 12 on May 5, 8 on May

6, 5 on May 7-20, then 15, 10 and 15 on May 21-23, and then 5

forever after that. This is from a 45 day forecast, so we won't

really see quiet conditions forever, but the forecast ends on June

16 with planetary A index of 5 until then.

F.K. Janda, OK1HH has another short forecast for geomagnetic

conditions, like last week. He sees the geomagnetic field quiet to

unsettled May 3-10, quiet to active May 11-12, and quiet to

unsettled May 13-19. That's it!

NASA released a new solar cycle prediction on May 1, but it wasn't

really new. These arrive at the start of every month, and remain the

same since March 1. On March 1, 2013 the prediction for the smoothed

International Sunspot Number at the cycle peak shifted from 69 to 66

for Fall 2013. The 2013 Autumnal Equinox begins in about four months

and three weeks. This week the May 2013 issue of CQ Magazine

arrived, and across the top of the cover was this headline: "Another

Double-Peak Sunspot Cycle?" We certainly hope so.

Time to review our 3-month moving average of sunspot numbers, which

has increased. The average daily sunspot number for February, March

and April was 85.2. The average daily sunspot number for the three

month periods centered on September 2012 through March 2013 were

81.2, 82.3, 74.4, 82.8, 73.6, 80.7 and 85.2. This is a moving

average, so 81.2 was the average for August through October 2012,

82.3 was September through November 2012 and so on. But this

involves a bit of cherry picking of the data, as the three previous

period's averages were 96.5, 91.9 and 89.9.

The average sunspot number for the month of April was 112.8, for

March it was 81.1 and February was 60.1.

Eric Ferguson, VE3CR of Burlington, Ontario sent his father-in-law

Bruce Jones an article about solar flares, and they both wondered

why there are no solar flares at the Sun's poles.

I passed this question on to Robert Steenburgh, KA8JBY who is a

Senior Space Weather Forecaster at the NOAA Space Weather Prediction

Center.

Robert wrote, "Flares are thought to originate from the deformation

of magnetic field lines which break and reconnect. There is a

latitudinal band in which this magnetic flux emergence (and hence

sunspot formation) and deformation occurs.

"Sunspots typically form at mid-latitudes (equatorward of around 40

degrees) at the beginning of the solar cycle, and the breeding

grounds drift towards the equator over the course of the cycle. This

behavior is attributed to the solar dynamo. See

http://solarscience.msfc.nasa.gov/dynamo.shtml.

"A cartoon depiction of the dynamo process is here:

http://www.nasa.gov/images/content/144061main_CycleDiagramLG.jpg

"You can find a paper on flare distribution for Solar Cycle 23 here:

http://www.ias.ac.in/jaa/junsep2006/JAA10.pdf

"There were 4 flares identified poleward of 50 degrees latitude in

that paper, out of a total of 20,186.

"The poles are usually dominated by coronal holes and 'open'

magnetic field lines that extend out into the heliosphere. So the

mechanisms for flare formation are generally absent."

David Moore sent a link to a NASA video showing ten coronal mass

ejections over five days in April:

http://www.nasa.gov/multimedia/videogallery/index.html?media_id=162261751

Mike Snyder, KN8J who lives a few miles south of Harrisville, West

Virginia in EM99lf wrote this morning, May 3: "My wife and I are

early risers. I mean real early. We're up about 3AM. Generally

speaking, 3 to 5AM produces some fair DX for me.

"Lately it's been getting a bit better on the 20 and 30 meter bands.

The South Pacific is usually open at these hours. I've managed a

couple QRP contacts with Hawaii. I've noticed parts of Europe open

as well. I had a solid QSO with OK1HB from the Czech Republic on

14.062MHz. I was running 100 watts barefoot for this one.

"This morning I finally worked a new one: A35JP in Tonga on 14.003

MHz running up two at 0736 UTC.

"Well, gotta go...someone just spotted FO/KH0PR!"

Mike runs a Cushcraft A4 antenna on a 40 foot tower with the two

rear elements askew due to high winds last month. On 160 and 30

meters he uses a fan inverted vee dipole at 35 feet.

He sent this final note: "Just worked A35UD on 10.108 MHz at 1010

UTC. Too bad I gotta go to work now!"

ARLP003 Propagation de K7RA

Solar activity pulled back over the past week, following a stellar

performance in the week prior. Average daily sunspot numbers were

down 34.3 points to 129, but average daily solar flux actually rose

9.7 points to 157.4. This was because solar flux values seemed to

lag behind last week's activity, raising this week's average in the

first few days of the current week.

The current prediction is for solar flux at 125 on January 18-20,

120 on January 21-22, 115 on January 23-24, 130 on January 25, 135

on January 26-28, 130 and 135 on January 29-30, 140 on January 31

through February 1, 150 on February 2, 155 on February 3-4, 150 on

February 5-11, then 145, 140, 135, 140 and 145 on February 12-16.

The predicted planetary A index is 10, 15 and 18 on January 18-20, 8

on January 21-22, 5 on January 23 through February 4, 8 on February

5, 5 on February 6-8, 8 on February 9-10, and 5 on February 11

through the beginning of March.

The most active geomagnetic day was January 13, but only in relation

to very, very quiet recent conditions. The mid-latitude A index was

10, and the K index only reached 4 in one three-hour period. The

college A index (from Fairbanks, Alaska) was 11 and 12 on January

13-14, with the K index reaching 4 in two 3-hour periods on February

13 and 5 in one 3-hour period on February 14. The reading before

that K index of 5 had a K index of 0.

There is a possibility of aurora on Sunday, January 20. NOAA reports

the geomagnetic field is expected to be at minor storm levels today

(January 18), active levels on January 19, and minor storm levels

again on January 20.

A strong solar wind on January 17 was from the waning effects of a

CME (coronal mass ejection) on January 13. On January 19 solar wind

may rise again as the result of a coronal hole rotating into

geo-effective position. A January 16 CME could cause a rise in

geomagnetic activity on January 20. Effects should decrease into

background levels by mid-day (UTC) on January 20.

The Australian Space Forecast Centre issued a warning at 2335Z on

January 17 about increased geomagnetic activity January 19-20 due to

a CME. For January 19 they predict quiet to unsettled conditions,

but with active to minor storm periods after 1200Z. For January 20

they predict unsettled to active conditions, with minor storm levels

possible.

OK1HH predicts geomagnetic activity will be quiet on January 18-19,

mostly quiet on January 20-21, quiet to unsettled January 22-23,

mostly quiet January 24-26, quiet January 27 through February 1,

mostly quiet February 2-3, quiet to active February 4-5, quiet

February 6-7, quiet to unsettled February 8-9, active to disturbed

February 10-11.

Jon Utley, K7CO reports that on January 11 he was in the state of

New York, and using a 5 element monoband Yagi at 100 feet he worked

XV1X at 1334Z and XW4XR at 1600Z on 10 meter CW long path.

Also on January 11, Jeff Hartley, N8II in West Virginia reported, "I

have operated every evening this week with poorer than expected

results. Before Thursday January 10, 12 and 10 meters were closed

here very shortly after sunset to all areas. A45XR was S9 on 10

meter long path Sunday morning January 6, but the band was never

open well to Europe unless I rechecked it a bit late. VR2XMT was

about S5-7 on 12 meter SSB long path as well Sunday. All of the

higher bands still seem to close pretty early including 20 meters

both west and north by 0200Z, but I expect by today things are

better. On 10 meters Thursday, KH6 was heard until past 2250Z and

there were west coast and South American stations on 10 until around

2230Z. I have been looking for Asia long path QSOs on 20 and 30

meters without much luck, but did manage to catch UK8OM on 30 meters

short path around 0100Z."

Rick Radke, W9WS of Balsam Lake, Wisconsin wrote: "Just wanted to

share an experience I had on Wednesday January 9. I was checking the

bands for DX. As usual, I start on 10 and work on down to 20 to see

what's open. Nothing was 'happening,' in fact there were very few

signals at all. So I went to 40 just looking for a ragchew and out

of nowhere there was ER4DX calling CQ with a big signal. We

exchanged 59 reports and went our ways. This was 1400 local (2000Z)

on a sunny afternoon in northern Wisconsin, a good three hours

before grayline on this end. In almost 50 years of hamming I've

never seen 5K+ miles of 40 meter propagation mid-day. Nothing

special here, running 1 kW to a vertical with a bunch of radials."

That is an interesting time to work Moldova. ER4DX is Vasily

Romanyuk, and just doing an internet search with his callsign yields

some clues that he operates a pretty serious big gun station. For

instance, using a popular search engine to search that callsign,

then hitting the Images option leads to many photos of big antennas.

W6ELprop indicates that between ER4DX and W9WS on 40 meters on that

date signals may have taken a 10 dB jump from 2000-2030Z, and

another 10 dB by 2230Z. I used 45.456 deg N, 92.42 deg W for Rick's

location, and using the grid locator from an image of a ER4DX QSL

card (KN38vk), the AMSAT tool at

http://www.amsat.org/amsat/toys/gridconv.html shows 48.438 deg N,

27.792 deg E. at the other end. W6ELprop shows this is a 5,016 mile

or 8,073 km path, and about 6 hours after sunset at 2030Z in

Moldova. So conditions were probably favorable, and ER4DX was

probably putting out a big signal, perhaps with a large 40 meter

Yagi.

Using today's date (January 18) shows that first 10 dB bump moving

out by 30 minutes, to happen around 2030-2100Z instead of

2000-2030Z.

Reg Beck, VE7IG of Williams Lake, British Columbia on January 12

wrote: "I had the long path openings on 10 and 12 meters for 3 days

here before they petered out. I still saw W6 stations working long

path after it closed for me after the 3 days. A4, A6, A9 and 7Z1

were worked on 10 meters; A4, A6, A7 were worked on 12 meters. What

was very surprising to me was the immediate resurgence of 160 meter

propagation right after the 10 meter long path propagation stopped.

Europeans all over the band and easily worked just like during the

sunspot minimum with relatively low noise levels. Pretty amazing

propagation up here in the northern end of the Pacific Northwest."

Reg is way up north in British Columbia, not down near the border.

Seattle is 47.7 degrees north latitude, Vancouver BC is 49.2

degrees, and VE7IG is just north of 52 degrees in Williams Lake.

Oleh Kernytskyy, KD7WPJ in Salt Lake City, Utah wrote: "Solar flux

was 170 on January 12. I called CQ with 5 watts and an indoor dipole

on 28.060 MHz from Salt Lake City, and immediately received a

response from Fred, N3FLL in West Chester, PA. He also operated QRP

- 5 watts and used a dipole. I was impressed with this contact,

because the eastern direction is blocked by the Wasatch Mountains."

In another email, Oleh wrote: "We had solar flux 158 and K=2 on

January 13. It produced a short opening on 28 MHz. I had a QSO with

CE2AWW, using 5 watts and indoor dipole. The distance between our

stations was 5707 miles."

Jon Jones, N0JK wrote with 6 meter E-skip news from Kansas: "Heard

the WR7NV/b DM25 and K0YW DM69 on Es around 0130 UTC on January 14

while I was mobile near El Dorado, Kansas EM17. The Nevada beacon

was in for over 30 minutes."

And finally, in last week's Propagation Forecast Bulletin ARLP002 we

mistakenly put Carl, K9LA in Indianapolis. Carl is in Fort Wayne,

Indiana.

Average daily sunspot numbers fell 13.5 points this week from 61.1

to 47.6. Average daily solar flux was about the same this week as

last, rising 1.1 points to 102.7. Geomagnetic indices were even

quieter this week than last.

Predicted solar flux is 115 on December 14, 120 on December 15-16,

115 on December 17-19, 110 on December 20-21, 115 on December 22-23,

110 on December 24-27, 100 on December 28-29, 95 on December 30

through January 3, 100 on January 4-5, and 105 on January 6-8. Solar

flux then jumps abruptly to 125 and 130 on January 13-14.

The predicted planetary A index is 5 on December 14-15, 8 on

December 16, 10 on December 17, 5 on December 18-28, 8 on December

29, 5 on December 30 through January 5, 7 on January 6-7, 5 on

January 8-9, 8 on January 10-11 and 5 on January 12-27.

OK1HH predicts the geomagnetic field will be quiet to unsettled on

January 14, mostly quiet December 15, quiet to unsettled December

16, active to disturbed December 17, mostly quiet December 18, quiet

December 19. A positive storm phase is expected December 20, with

active to disturbed conditions December 20-21, quiet to unsettled

December 22, mostly quiet December 23, quiet December 24, quiet to

unsettled December 25, mostly quiet December 26, quiet December 27,

quiet to active December 28, quiet December 29, quiet to unsettled

December 30-31, quiet January 1-4, active to disturbed January 5-6.

Both NASA and NOAA have tweaked their predictions for the peak of

the current solar cycle next year. To see the NOAA changes, go to

http://www.swpc.noaa.gov/weekly/ and select PRF 1940 and go to page

12. Then open another browser window and select PRF 1944 and go to

page 16.

Notice that in the November prediction, the cycle peaks at 90 in May

through July 2013, and the smoothed sunspot number for January

through April is 81, 83, 85 and 88. In the December prediction, we

see two instead of three peak months, June and July 2013. The

numbers for January through May are 79, 81, 83, 86 and 88. This is a

marginally weaker predicted peak for cycle 24.

The latest NASA prediction is at

http://solarscience.msfc.nasa.gov/predict.shtml

The change here is from 73 to 72 for a smoothed sunspot number

maximum in the December 10 prediction compared to the November 2

prediction. The other change is last month when they wrote "The

smoothed sunspot number (for 2012/02) is already nearly 67 due to

the strong peak in late 2011 so the official maximum will be at

least this high." This month the end of the line was changed to "at

least this high and this late."

Seen on Bob Kile's (W7RH) Facebook page on Tuesday: "For those low

band operators out there. The solar activity remains low and the

solar wind is under 300km/sec. That means West Coast to EU, boys! I

have six in the log last Saturday night and there have been West

Coast openings since last Friday."

I believe Bob is referring to 160 meters.

Lloyd Berg, N9LB of Oregon, Wisconsin (Oregon is a town just south

of Madison, Wisconsin) wrote about the 10 Meter contest:

"This year required a continuous effort on Friday evening, all day

Saturday and all day Sunday, including numerous 'dead band' times of

waiting and wondering if the band was going to come back or not. I

can see a large chunk of the band on my FLEX - Software Defined

Radio panoramic display - and when I say the band went dead, I see

it happening just like somebody turned down the RF gain - only took

a minute or two to extinguish all signals. I'd actually transmit

just to make sure the antenna was connected. I also looked out the

window many times to see if the antenna was still there (it was).

Really odd.

"At the beginning of the contest, the solar numbers looked awfully

low for decent 10m propagation: SFI=97, SSN=23, A=1, K=0. Conditions

were very weird from my Wisconsin QTH. The band kept going dead,

then we'd have a bit of garden variety E-skip 'here-and-there,' then

dead again. Then it would open up real wide, going way beyond simple

E-skip... North, South, East and West all at the same time.

"Worked everything East of the Mississippi in North America

(E-skip). Worked Hawaii, more Alaskans than in any other single

contest ever, many BC, and a NWT, but never heard most of the Rocky

Mountain states. Easy to work every active station in South and

Central America, and the Caribbean - day or night. Nice and strong

but short-lived openings to Azores, Cape Verde and Canary Islands.

"Worked several ZSs, VKs, ZLs and an E51 during a few short precious

minutes of openings on Saturday evening and again on Sunday

afternoon. No Japan or Asia heard at all. Only European contacts

were a couple of Spain and Portugal, again during a very brief

opening (well after their sunset)."

Thanks, Lloyd!

Jeff Hartley, N8II of West Virginia wrote, also about the 10 Meter

contest: "Sunday was noticeably better than Saturday in the 10M

contest this past weekend. I only worked about 15 EU stations all

weekend, but conditions to the west coast were extremely good and we

had plenty of Es Friday night and Saturday night into MN, WI, SD,

IA, MO, KS, and OK as well ME and VE1, VE9, VY2. The last hour

featured Es into KP4 and NC, SC, AL, KY, TN, FL, MS, AR, LA and TX.

"Highlights were working A45 around 1630Z Saturday and a great long

path Asian opening on Sunday which lasted for hours, starting around

1250Z on CW with about four JAs, BD7 at 1302Z, BV1 at 1308, XV1 at

1405, HS0 at 1414,and 9V1 at 1538, and also called on phone by HS0

at 1506. Sunday was extremely good to the west coast from 1710Z thru

2235Z, one WA station running a half watt was a solid S4 and mobiles

had solid signals. All states were worked on CW and only missed AK

on phone. There was propagation of some sort to all states at one

time or another with only the very close states on backscatter

only."

Another BPL bites the dust

+ BPL Provider IBEC Announces Shutdown

 

IBEC -- one of the very few remaining operators of Access BPL systems -- has announced that it is closing down. In an undated announcement that appeared on the IBEC website, the company announced that it has "no other option than to close our doors and cease operations." IBEC claims that it cannot recover financially from the April 2011 tornadoes in Alabama that "ravished [sic] some of our major service areas." IBEC provided Internet service via broadband over power lines (BPL) to rural communities.

In this letter dated December 23, 2011, IBEC notified their customers that it would be discontinuing service. According to a utility company that serves portions of Tennessee and Virginia, they only found out about IBEC's closure on January 3, 2012. Click here for a larger image.

 

"While we regret the loss of jobs brought about by IBEC's BPL business failure, in the long run the rural areas that IBEC was trying to serve will be better served by broadband technologies that are superior to BPL and do not pollute the radio spectrum," said ARRL Chief Executive Officer David Sumner, K1ZZ. "While initially IBEC was cooperative in addressing the ARRL's concerns about interference to licensed radio services -- including Amateur Radio -- the ARRL was dismayed to find that the systems as actually deployed fell short of meeting even the inadequate requirements of the FCC's rules. We hope that this latest in the long string of Access BPL failures will persuade the few remaining fans of BPL to turn their attention elsewhere." Read more here.
