I think that corona holes and the resulting solar windstream are the
biggest disruption to propagation. At least here in the higher

poorer condition today even though the K index is back to 2 (5 last
night).

I can hear lots of noise very few stations on 20, not wall to wall
traces as would be normal this time of day. Seems to be slowly getting
stronger.

Seems to take about 2 days for things to get back to normal after
particle impact. I look at that "current auroral oval" map at:

If there is a white mist covering the midwest, its usually bad news
(like today).
