Moderate M1.9 solar flare erupted off the southwest limb

Moderate M1.9 solar flare erupted from the vicinity of departuring regions 1879 and 1877 at the southwest limb. This latest event erupted at 13:51 UTC on October 31, 2013.

Solar activity was relatively calm in the past 24 hours compared to strong activity recent days. 

There are currently, 6 visible sunspots on the Earth side of the Sun and only AR 1884 is Beta-Gamma-Delta class – capable of producing the strongest flares. A small new region formed near AR 1882 and was numbered 1888. NOAA/SWPC forecasters estimate 50% chance of an M-class and 10% chance of an X-class solar flares in the next 24 hours.

We are currently expecting impact of CME released by M4.4 on October 28, 2013. The proton flux measured by GOES is currently decreasing.
