SEATTLE, WA, Aug 19, 2005--Not much solar activity occurred
over the past week. A few days ago Earth entered a solar wind stream which raised geomagnetic activity, but not to the level of a storm. Sunspot numbers and solar flux are expected to remain low but rise moderately again around August 26 and through the end of the month. Geomagnetic conditions should stay mild, with unsettled conditions returning around August 23-26. Frank Donovan, W3LPL, of Glenwood, Maryland sent in some interesting Web links (1) (2) regarding 6 meters and sporadic E propagation. On the k1six.com link, the dates may be a bit confusing, because the title says the graph covers the period from 1995 to present, but the dates along the X axis run from early May to the present. This graph shows cumulative activity during May through August over the past decade, so the data isn't just from this year. It illustrates when sporadic E propagation across the Atlantic is the most common--in late June and early July. We get reports of TV and FM DX during sporadic E season and sometimes mention them in the bulletin. Doug Allen, W0AH, of Woodland Park, Colorado, wrote to say that receiving FM and TV stations from more than 1000 miles away via sporadic E is fairly common in the summer. He has personally logged more than 3000 FM broadcast stations via sporadic E, and a few hundred of those were 1450-1500 miles distant. For more information concerning radio propagation and an explanation of the numbers used in this bulletin see the ARRL Technical Information Service Propagation page. An archive of past bulletins is on the ARRL Web site. Sunspot numbers for August 11 through 17 were 35, 47, 33, 34, 49, 48 and 42, with a mean of 41.1. The 10.7 cm flux was 75.9, 76.2, 75.4, 74.8, 75.8, 75.8 and 77, with a mean of 75.8. Estimated planetary A indices were 6, 6, 16, 10, 8, 19 and 18, with a mean of 11.9. Estimated mid-latitude A indices were 2, 3, 14, 6, 6, 12 and 11, with a mean of 7.7. http://www.arrl.org/news/stories/2005/08/19/2/?nc=1 (K7RA, ARRL) dxAce Michigan USA |
