There was an M1.1 flare this evening at 20/2310 UT.  It was on or behind 
the limb of the sun from an as yet unnumbered sunspot group.  This is 
believed to be from one of the 2 active sunspot groups that went over 
the other limb 2 weeks go.  These 2 groups are expected to continue to 
be active as they move across the visible side of the sun over the next 
2 weeks.  There were 3 small flares that preceded the M1.1 flare at ~12 
degrees South solar latitude and one small flare at ~06 degrees South 
solar latitude. These are the approximate latitudes of the 2 groups that 
went over the other limb 2 weeks ago.  The solar flux for today was 76 
so it is already rising despite the fact that the 2 active areas haven't 
appeared on this side of the sun yet.
