Thirty meters really got knocked out yesterday with a total fadeout (at least 
at this QTH in central Michigan) yesterday.   The NOAA Spaceweather Center 
solar x-ray flux graph on my UI-Webserver entry page tells the story.

(Thirty meters is EXTREMELY sensitive to the solar X-Ray flux, and fades 
rapidly when the flux spikes upwards.   Since this is coming from the sun, the 
daylight side of the earth at the time of the flare is far more affected than 
the dark side.  Note that the dates and times on the graph are UTC)
