Since the last report I sent, two more M-class flares are reported:
20-01-2010 0748 UT at Flux M 1.7 and 20-01-2010 1100 UT at Flux M 1.9
The Sun is clearly coming more awake. In the last 24 hours, the largest
flare was an M2.3 flare with peak at 1341
UT on January 19. They are all coming from NOAA AR 11041 (old 11039,
Catania 37). More M flares are likely. These flares are causing radio
blackouts in sunlit regions. The blackout is most noticed on lower HF
bands, and extend up into the 20 MHz frequencies. Expect some geomagnetic
activity due to the arrival of fast solar wind from a coronal hole, in
addition to these radio blackouts. Conditions on HF therefore will become
more variable and degraded in the next days.
