[HCARC] Solar Activity 21 Apr 15

[Kerry Sandstrom]

There were 7 M-class X-ray flares today.  One of them was just over the 
east (rising) limb and the remainder were near/on the West (setting) 
limb.  The new sunspot group that I expect hasn't made it over the limb 
yet.  In the meantime, one of the old groups has gotten active just 
before it disappears over the west limb.  Solar flux is still 150 or 
over and the sunspot number has been running over 100.  Absorption has 
been fairly high today due to number of M-class flares.
