[DX-NEWS] ARLP024 Propagation de K7RA
SB PROP @ ARL $ARLP024 ARLP024 Propagation de K7RA ZCZC AP24 QST de W1AW Propagation Forecast Bulletin 24 ARLP024 >From Tad Cook, K7RA Seattle, WA June 18, 2010 To all radio amateurs SB PROP ARL ARLP024 ARLP024 Propagation de K7RA Average daily sunspot numbers were up 2.5 points from last week, despite the fact that there were no sunspots at all this week on June 15-16. A new sunspot group 1082 emerged yesterday, June 17, and yielded a daily sunspot number of 14. A nice thing about this spot is that it is all the way over on the east side of the visible solar disk, meaning we will probably see its effects as it moves across the sun. All other recent sunspots emerged toward the west side, which meant that they went over the horizon fairly quickly and disappeared. Last week there were four sunspot groups visible at different times. Group 1078 disappeared on June 12, 1079 and 1080 both were gone on June 14, and on June 15 1081 was gone. Geomagnetic activity peaked on June 16 with the planetary A index at 19 and high latitude college A index at 42. This should decline over the next couple of days. We did not receive a prediction from Geophysical Institute Prague this week, but NOAA/USAF say that the expected planetary A index for June 18-28 is 10, 5, 5, 5, 5, 5, 8, 12, 15, 15 and 8. This shows unsettled to active geomagnetic conditions for Field Day weekend, June 26-27. The same prediction shows solar flux at 70 on June 18-24, then 75 for June 25-30. Glen Stuart, N7NRA of Mesa, Arizona sent this in about recent 10 meter activity. "N7YU, Dave, in Chandler, AZ, and I had QSOs into Rarotonga last evening on 28.445 at about 0045Z, 14 June. The op on the other end was E51JD, Jim. There was some QSB, but we were reporting 57 on both ends. I don't know how much power Dave was running. I was using 100W. We both use Butternut HF-9Vs. His is ground mounted, mine is roof mounted with the base at about 15 feet above ground. When I built my shop I had the roofers install a carpet of chicken wire between the shingles and the tar paper. My counterpoise is about 16 x 50 feet and works well. Things are looking up for the higher frequencies". On that same date, June 14, the K0KP six-meter beacon was copied in the Netherlands. Rex Greenwell, K0KP lives in Duluth and operates a 100 watt beacon on 50.073 MHz at the 50 foot level on a commercial broadcast tower in grid square EN36wt. Here is the message from Rex. "This is an email I received from PF7M today - Netherlands. This was at 01:50 AM Central time. 6M - Europe to Minnesota in the wee hours of the AM. - Rex K0KP EN36 20 mi. NW of Duluth, MN. Hello Rex, This morning round 06.50 UTC I have received your K0KP/B beacon on 50.073MHZ. Just audible at 419 with my 6 element Yagi at 20 meters. Locator here: JO33BA. 6 meters was open from here to GM and OY, so think it was some extended Es into EN36. Not any NA present on 6M at this time. 73's Johan - PF7M" Several readers sent in links to articles on our sun's recent strange behavior, including this one, http://tinyurl.com/27nogws and this one http://shar.es/myBSb on the NASA Solar Observatory. In last week's bulletin we raised the question about adjusted solar flux values, and why they are adjusted to compensate for the variation in the distance between earth and sun. The solar flux values we present here are the values as measured at the observatory in Penticton, British Columbia. You can see them at http://tinyurl.com/ks8tvn. They come from the 2000z reading in the third column from right, with the heading fluxobsflux. The next column to the right, fluxadjflux, is the adjusted value. They are adjusted up or down to reflect a value based on the average distance of our planet from our sun. On 6-17-2010 at 2000z the raw observed value was 70.4, and the adjusted value was 72.7. This is because we are now further away from the sun than other times of the year. Of course, we are interested in the observed value, because that is a measure of the radiation hitting our ionosphere. But if we wanted to keep track of adjusted solar flux to gauge solar activity, this would show us more realistically what the sun is actually doing. Back on April 5 the observed and adjusted readings show the same value, but in January, we were closer to the sun, so the value was adjusted downward. This weekend is the All Asia CW DX Contest, and HF conditions should be fair. There are no predicted geomagnetic disturbances. The new issue of WorldRadio online should be out this Sunday, June 20, and there is always an informative column on propagation by K9LA. Check it on Sunday at http://www.worldradiomagazine.com/.

The operators will be EA3AS, EA3ATM, EA3DW, EA3FKX, EA3NT and F4BKV. Last year's activity run for a few hours only owing to rough seas. QSL via EA3NT. [TNX DX World] F - A few days after Charles de Gaulle's famous appeal of 18 June 1940, which was the origin of the French Resistance to the German occupation during World War II, the clandestine sea crossings between Brittany and England started. Commemorating those events of seventy years ago, special callsign TM70TC will be activated from Finistere from 26 June to 10 July. QSL via F6CNM.
