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) ____________
Two M-Class flares occurred since my listing of flares. The last one is over M5.0 - so, hold on tight. We're in for a ride. If you can dodge the Radio Blackouts on the sunlit side of the Earth, you'l
I wrote 24 and 25 January in my recent message(s). Please change those to 14 and 15 January. Sorry. Fat fingers and thick brain. -- 73 de Tomas, NW7US (AAR0JA/AAA0WA) ________________________________
