During the last weekend of this month (the CQ WW SSB contest weekend, 30 and 31 October 2004), we should experience good conditions. While we won't see very high sunspot counts, we do have enough act
Hello, This is the last update before the start of the CQ WW SSB contest of 2004. With the contest starting at the start of 30 October 2004 UTC, and running through the end of 31 October 2004 UTC, we
Say 'hello' to Murphy. Who would have thought that the Sun would wake up in a cranky mood, just as the contest gets under way? Based on the 27-day rotation cycle, we did not expect the see a rise in

On January 14, 2005, there was a small solar flare that was located on the solar central meridian. The associated plasma that was ejected, directed squarely toward Earth, will arrive simultaneously w
I've posted a list of the flares of 24 January through the start of 25 January, 2005 (up to the writing of this message, which is 0425 UTC 25 January 2005) at http://hfradio.org/forums/viewtopic.php?
Just as I hit the SEND button for the last message regarding the flares, a new flare, level M1.0, occurred. So, add another one to the total so far. -- 73 de Tomas, NW7US (AAR0JA/AAA0WA) ____________
