Solar activity is moderate.
Region NOAA 11158 produced an X-class flare yesterday (14th Feb)
Since then it remains magnetically complex. An X-class flare
is still possible from this region. An M-class event
is likely. A C-class flare is also possible from
region NOAA 11161.
NOAA 11158, S21 W21 (X= 326,Y=-245). Beta-gamma-delta region. M-class
flare likely, X-class possible.
