Howdy, DX hounds.|
The Sun has clearly quieted down considerably since the beginning of 2004. The end of Solar Cycle 23 is expected between 2006 and 2007, so we are far into the decline of the current cycle. We'll see an occasional coronal hole, and short-lived flare-ups of solar activity with associated coronal mass ejections. But, they will be spaced farther apart than what we've seen even as recent as July of this year.
During October 2004, and especially during the last weekend of this month (the CQ WW SSB contest weekend), we should experience fair conditions. We won't see high sunspot counts and the 10.7-cm flux will be averaging around 100 to 110. This will mean that 20 meters will be the primary contest band, with 15 meters a player during the daylight hours, though with a lot less umph than the previous couple of years. There will be some marginal activity on 10 meters. The lower bands (40 through 160) are getting better, though.
During the middle of October, we'll see a bit of geomagnetic activity from a coronal hole, but nothing that will make conditions overly rough. In general, this whole month, conditions will stay on a more-or-less even moderate level.
I keep a daily update of the "Last Minute Forecast" table at
which is part of the http://prop.hfradio.org suite of propagation resource pages.
I'll create updates as we get closer to the CQ WW SSB weekend. And, I'll be posting my predictions for the CQ WW CW weekend, too. Good luck, DXer's!
