What is with propagation right now ???

I checked out http://hfradio.org/propagation.html

They state that there is a sunspot group:

"24 (NOAA 0606) is the most active as it produced a B4.4 flare."


A class B flare is barely a peep. Need a least a class M (100X stronger)
to have much effect.


Is that why I'm finding that the 49, 41, 31 meter bands all messed up ???
Massive fade out of usually very strong and relaible signals that are
falling below the noise floor at times.


I see neither significant solar activity nor magnetospheric disturbance
at http://www.sec.noaa.gov/today.html.

Ionospheric soundings at http://digisonde.haystack.edu/latestFrames.htm
look normal.
