[DX-NEWS] ARLP041 Propagation de K7RA
SB PROP @ ARL $ARLP041 ARLP041 Propagation de K7RA ZCZC AP41 QST de W1AW Propagation Forecast Bulletin 41 ARLP041 From Tad Cook, K7RA Seattle, WA October 9, 2009 To all radio amateurs SB PROP ARL ARLP041 ARLP041 Propagation de K7RA Sweet memories of that 11-day run of sunspots ending on the second day of this month will eventually fade. So far the number of spotless days is seven--or perhaps eight by later today--with the last sunspot seen on October 1. A peek at http://stereo.gsfc.nasa.gov/ for the latest STEREO images shows two active areas in our Sun's southern hemisphere beyond our direct view, but it is hard to tell if these will emerge as sunspots when they appear over the eastern limb. A rough guess has the first one possibly emerging around October 10, and the second around a week later. Currently the solar flux forecast shows flux values lower then 70 through October 15, then around 72 during the two-week period from October 16-30. The second spot is seen on the look-ahead image, and is passing into the invisible area, now slightly more than 60 degrees wide in latitude, or about one-sixth of the solar surface. The same NOAA/USAF forecast predicts the same very quiet geomagnetic conditions we've seen for some time, with a planetary A index around 5. Two very small increases are predicted for October 11-12, with an A index of 7, and October 24-25, with the A index at 8. Average sunspot numbers for the week dropped 15.3 points below the September 24-30 period, and average daily solar flux for the week declined 2.2 points to 70.5. Regarding the invisible area on the other side of the Sun, this is becoming smaller as the Ahead and Behind STEREO platforms slowly converge. You can figure out the size of the dark area in terms of degrees by going to the Where is STEREO Today? page at http://stereo-ssc.nascom.nasa.gov/where.shtml. The last figure at the bottom of the page is Separation Angle A with B. Subtract this value from 180 to get the size of the dark area. Currently early Friday morning it shows 119.702, which corresponds with a dark area (beyond the sight of the A and B platforms) of 60.298 degrees. At http://stereo-ssc.nascom.nasa.gov/where/ you can see how wide that invisible area will be at any date and time in the future. On October 1 at 1800z the blank area was 61.7 degrees wide, on November 1 it will be 56.3 degrees, and December 1, 51.6 degrees. The non-visible area will be exactly 60 degrees wide around 0021-0028z on October 11. In 2010 that invisible area will shrink from 47.7 degrees on January 1 to 9.3 degrees on December 1. The entire Sun will be visible beginning on February 6, 2011 around 1302-2047z. After that, the blank spot in STEREO's vision will be Earth-facing, and as it grows the information can be filled in from observation here on Earth. Larry Banks, W1DYJ of Woburn, Massachusetts sent in an article from New Scientist magazine titled, Phantom Storms: How our weather leaks into space. It has many interesting details about our ionosphere and stratospheric warming. Read it on the web at, http://snipr.com/scukl. Giles Berry, KE3CR of New Castle, Delaware commented about last week's reports of VHF propagation along fog banks. He recalls that in the early 1950s when television first came to the state of Maine, TV reception seemed to improve with fog. Giles notes that on a foggy night he could receive television broadcasts from Boston reasonably well. He was on the mid coast of Maine. Patrick Hamel, W5THT of Long Beach, Mississippi notes, Here on the Gulf of Mexico coast we have always known that when we get fog, we can talk from Florida to Texas 'under the inversion' on 2 meters. It also works on 6 meters, and I regularly heard other stations making contact on 2 meters and then jumping to the higher bands during fog conditions. Gus Malmberg, SM0EGK says, When I read WA2AMW's comments about the extraordinary conditions on 2m, I recalled what happened early in 1963, when one could listen to all of northern Europe and see many band I TV stations for a few days. As a youngster I didn't understand the mechanism, but have since realized that it must have been an extreme temperature inversion. In 1963 we had a solar minimum. He continues, I worked for fifteen years as a radio and television transmitter engineer for the Swedish Telecommunication Administration, but have never again experienced something like that! Alan Vigeant, KI6HPO of San Marcos, California wrote, I'd like to inform you of past and most recent conditions here in NE San Diego County. Since early April, I've been having daily chats with my good friends at the Santa Barbara Amateur Radio Club, which is situated about 165 miles NW of my QTH. Alan continues, I am at 2,200 feet of altitude, on the SW rim of what I like to call the Palomar Ridge, which is about 5,600 feet above sea level. Between the two rims is what I call the 'Palomar Trench.' My QTH is about 12 miles SW of the Palomar
