A new active region AR11162 has emerged adding to the possibility of further flare events. Observations should be sent as soon as possible to the Solar Section Director with details of date, time (UT) of start, peak and end of flare event, location and intensity.
Big Bear Solar Observatory activity warning is reproduced below:
Solar activity is high.
A new region now numbered 11162 has erupted north of 11161. It has produced two M-class flares overnight. The region is magnetically complex and rapidly growing. M-class flares are expected and an X-class flare is possible.
Region 11158 has simplified somewhat but remains capable of an M-class event.
NOAA 11158, S19 W63 (X= 820,Y=-264). Beta-gamma-delta region. C-class flares expected, M-class flare possible.
NOAA 11162, N20 W06 (X= 96,Y= 441). Beta-gamma-delta region. M-class flares expected, X-class flare possible.
Positions as of February 18, 2011 at 19:00 UT.
