DX-ers, et al.,


Heard a sudden enhancement in white noise on 50.125 this morning
while working a nice 6-m opening.  It had to be the Sun.  Sure enough,
the GOES X-Ray graph showed a rising flare in the M-Class range, while
the noise was raging on 6-m.

Flare got up to about the M-8 Class range, falling short of X-Class on the
logarithmic scale.

Propagation was "sterilized" on 6-m and 10-m for a few minutes, but, as the
flare ceased, stations came back on 6-m and heard many beacons on 10m

Time of flare-noise noted here on the atomic desk-clock, 09:31:30 MST,
or 16:31:30 Zulu, Sunday, July 8 2012..

It's always a privilege to be on the air and to hear these things in 
real-time
from the sun.  For some of us, it's the only Radio-Astronomy we get to do. 
;-)

Here's the URL for the 1-minute resolution X-Ray graph from the satellite:
