Dear RHESSI Collaborators,
The level of solar activity is now low. NOAA 12302 has been the most
flare-productive region over the past 24 hours, but it has already
rotated over the North West limb. NOAA 12297 has decreased in number
of spots, spot area and complexity over the past 24 hours as it has
rotated up to the South West limb. This region is now classified as
a beta-gamma-delta/E-type sunspot group and was the source of a C1.8
flare on 19-Mar-2015 at 08:15 UT. More C-class activity is possible
over the next 24 hour period as 12297 rotates over the South West
limb, with a small chance for an isolated low M-class flare.
The position of NOAA 12297 on 19-Mar-2015 at 23:00 UT is:
S17W90, ( 921”, -279” )

Dear RHESSI Collaborators,
Solar activity is at a moderate level. NOAA 12297 has decreased in
number of spots over the previous 24 hours, while maintaining spot
area and a beta-gamma-delta magnetic classification and increasing
in modified Zurich class to an F-type sunspot group. This region
has shown a decrease in flaring rate, but was still the source of
the largest magnitude flare since yesterday’s message, an M1.0 on
17-Mar-2015 at 22:49 UT. Further low M-class activity is possible
from 12297 as it rotates up to the South West limb.
The position of NOAA 12297 on 18-Mar-2015 at 16:00 UT is:
S16W73, ( 886”, -230” )

Dear RHESSI Collaborators,
NOAA 12297 has continued to decrease in both size and complexity as it
approaches the western limb. As a result, solar activity has
diminished substantially with only a few C-class flares since the last
message. The target region retains some mixed polarity flux in its
trailing spot that may produce additional intermediate level events
over the next 24 hours.
The position of NOAA 12297 on 17-Mar-2015 at 16:35 UT is:
S17W62, ( 815", -226" )

Dear RHESSI Collaborators,
Solar activity continues at moderate levels with two M1 flares since
the last message. NOAA 12297 is showing signs of polarity mixing in
its trailing spot but may be beginning to decay. Still a good chance
for additional low M-level events over the next 24 hours.
The position of NOAA 12297 on 16-Mar-2015 at 16:35 UT is:
S18W48, ( 683", -219" )

Dear RHESSI Collaborators,
Solar activity remains at moderate levels. The largest event since the
last message was an M1.0 flare at 09:36 UT today, although a
long-duration C9.1 flare at 01:15 UT was also associated with a halo
CME. NOAA 12297 has begun to show signs of decay but retains its delta
configuration. At this time we are ending the Major Flare Watch
campaign, although further low M-level activity is still possible.
The position of NOAA 12297 on 15-Mar-2015 at 12:35 UT is:

Dear RHESSI Collaborators,
Solar activity has diminished slightly with only an M1 flare and
several C-class events since the last message. The target region NOAA
12297 retains its beta-gamma-delta configuration but is showing less
signs of development. There is a large filament to the southwest of
the region which could lead to moderate flaring if it erupts. Major
Flare Watch shall remain in effect for a further 24 hours.
The position of NOAA 12297 on 14-Mar-2015 at 16:35 UT is:

Dear RHESSI Collaborators,
Activity from NOAA 12297 has been moderate over the past 24 hours with
the occurrence of several low M-class flares. The region retains its
beta-gamma-delta/D-type configuration and is bright in H-alpha images.
The trailing spot is showing signs of rotation and there is polarity
mixing near the leader spot. Chance remains for another >M5 flare.

Dear RHESSI Collaborators,
The target region NOAA 12297 was the source of an X2.1 flare at 16:11
UT yesterday. The region has continued to develop and has formed
another delta spot in its leading portion. Further M-level activity
expected with chance for an additional X-class flare. Major Flare
Watch remains in effect.
The position of NOAA 12297 on 12-Mar-2015 at 10:04 UT is:

Dear RHESSI Collaborators,
Solar activity continues at moderate to high levels. NOAA 12297
remains active and has produced two M2 flares as well as several
C-class flares since the last message. The region is currently
undergoing further development as negative polarity flux emerges
within the northern penumbra of the main positive polarity spot.
Additional M-level activity expected with chance of a low X-class
flare. Major Flare Watch remains in effect.
The position of NOAA 12297 on 11-Mar-2015 at 10:04 UT is:
S16E20, ( -318", -154" )

Dear RHESSI Collaborators,
Solar activity is high. The target region NOAA 12297 has produced
three ~M5 flares since the last message. The dominant trailing spot
maintains its delta configuration with smaller satellite spots
coalescing to the north. Major Flare Watch shall remain in effect due
to the increased likelihood of additional high M-level activity over
the next 24 hours.
The position of NOAA 12297 on 10-Mar-2015 at 10:04 UT is:
