</address> <pre> </pre> Dear Collaborators,
<br />NOAA 12817 was the source of numerous B-class flares as well as
two C-class flares (C1.9 and C1.5) in the past 24 hours. 12817 has
been designated as a beta/D-type region, with increasing its sunspot
area and number of spots. Today the target will switch to this region
that continues to show flux emergence. Further B-class activities are
expected and additional low C-class events are very likely when 12817
rotates to the west limb.
<br />The position of NOAA 12817 on April 21 at 03:30 UT is:
<br />N18W64 (817&quot;, 329&quot;)
