Dear RHESSI Collaborators,

NOAA 12158 was the source of a long-duration M4.6 flare that began at
23:12 UT yesterday, and shall be the new target region. The entire
region has a reversed polarity for the northern hemisphere and has
been upgraded to a beta-gamma-delta configuration due to mixed
polarities within the trailing penumbra. It is also showing signs of
sustained bright H-alpha emission around its magnetic inversion line.
At this time we are implementing a Major Flare Watch campaign due to
the increased probability of an M5 flare or greater over the next
24-48 hours.

The position of NOAA 12158 on 9-Sep-2014 at 13:18 UT is:

N15E20, ( -315", 135" )
