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:
S17W32, ( 490", -182" )

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:
S17W23, ( 361", -174" )

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.
The position of NOAA 12297 on 13-Mar-2015 at 10:04 UT is:

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:
S16E08, ( -129", -149" )

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:
S16E33, ( -507", -166" )

Dear RHESSI Collaborators,
Solar activity is at moderate levels. The target region NOAA 12297 has
produced several C-class flares since the M9.2 flare two days ago. The
region is now classified as having a beta-gamma-delta/D-type magnetic
configuration and is showing signs of flux emergence along its
trailing edge. This positive polarity flux is emerging into a negative
polarity penumbra, which may lead to additional high-M-level activity.
Major Flare Watch shall remain in effect.
The position of NOAA 12297 on 9-Mar-2015 at 08:35 UT is:

Dear RHESSI Collaborators,
The level of solar activity is moderate. Yesterday’s target region,
NOAA 12297, is classified as a beta-gamma/D-type sunspot group after
rotating further onto the visible disk. This region has produced two
C-class flares since yesterday’s M9.2 flare. The MM#003 Major Flare
Watch will continue for at least 24 hours, as NOAA 12297 retains the
potential for additional flaring above the M5 level.
The position of NOAA 12297 on 08-Mar-2015 at 22:00 UT is:
S17E54, ( -749", -212" )

Dear RHESSI Collaborators,
The target region near the southeast limb was the source of an M9.2
flare at 21:59 UT on 7-March-2015. The region is now designated as
NOAA 12297 although its magnetic configuration is uncertain. At this
time we are implementing a Major Flare Watch campaign due to the
increased likelihood of another >M5 flare over the next 24-48 hours.
The position of NOAA 12297 on 7-Mar-2015 at 22:35 UT is:
S17E68, ( -858", -237" )

Dear RHESSI Collaborators,
Solar activity is at a moderate level. The region beyond the South
East limb that was mentioned in yesterday’s message has continued
to produce more flaring activity over the past 24 hours, including
three low M-class events (the largest being an M3.0 on 06-Mar-2015
at 04:14 UT). Further C-class activity is expected over the next
24 hours, with a good chance for additional low M-class flares.
The approximate position of this region on 06-Mar-2015 at 16:00 UT is:
S19E90, ( -914", -312" )
