Dear Collaborators,

The largest X-ray event in the past 24 hours was an isolated B1.7 flare
at 04/15/00:02 UT, produced by the limb region (S22E85) mentioned in
the last message. This limb region also produced a few A-class flares.
The target region NOAA 12814 was the source of six high A-class flares.
12814 has been classified as a beta/C-type region with increasing in its
sunspot area and number of spots. It shows some opposite flux emergence
in its leading portion. More B-class activities are expected with a change
of a C-class event in the following 24 hours.

The position of NOAA 12814 on April 15 at 07:30 UT is:

S22W22 (333", -277")
