When we get a healthy solar flare followed by a Coronal Mass Ejection (CME), you will get some heightened propagation
It usually occurs just as the Auroral propagation is ending. This was the case last Tuesday afternoon.
Around midday, many in the northern latitudes were working 6 and 2 Meter Aurora. Around 23:00 UTC it ended and 10-Meters lit up. There were many trans-continental QSO's, plus the Carribean and Hawaii.
In a 2-hour period, I had 10-Meter PropNET PSK31 connections to Connecticut, Puerto Rico, Mexico and Hawaii, plus and number of captures in between.
To be ready for such events, Spaceweather.com is a good source of knowing when. The realtime maps at http://www.PropNET.org
are excellent sources of happenings. DX Sherlock is a good source, but tends to get reports after the fact on 10 Meters (work DX then report).
I don't know what to expect this weekend. Historically (5 year measurement) August 7-8 are fairly good Es days, but I have some concerns what the solar events of the past fews days have done to Es overall. My experiences have shown that an active Sun will hurt Es over the long-haul. It has become fairly quiet and I hope Es return with a vengence.
