Lots of solar flares

Space Weather report solar activity is high. In just 48 hours, monster sunspot AR2192 has produced a series of seven M-class solar flares of increasing intensity

The eruptions crossed the threshold into X-territory with an X1-class flare on Oct. 22nd. NASA’s Solar Dynamics Observatory recorded a powerful flash of extreme UV radiation in the sunspot’s magnetic canopy at 14:30 UT.

Remarkably, not one of the explosions so far has hurled a significant CME toward Earth. The primary effect of the flares has been to ionize Earth’s upper atmosphere, causing a series of short-lived HF radio communications blackouts. Such blackouts may be noticed by amateur radio operators, aviators, and mariners.

Earth-effects could increase in the days ahead. AR2192 has an unstable ‘beta-gamma-delta’ magnetic field that harbors energy for powerful explosions, and the active region is turning toward Earth. NOAA forecasters estimate at 65% chance of M-class flares and a 20% chance of X-flares during the next 24 hours.

————————————

This could be an interesting propagation week for both amateur radio operators and commercial broadcasters.  According to Space Weather, sunspot AR2192 has produced at least 7 M-class solar flares.  More flares may be on the way.  So far, the only effect has been a temporary interruption of HF communications lasting only a few hours.
