Dear RHESSI Collaborators,
Solar activity remains very high with the target region NOAA 11429
producing an X5.4 flare at 00:02 UT today. The region has grown in size to
over 1000 uh and has become highly sheared with its polarity inversion line
aligned in the east-west direction. Further C- and M-level activity
expected with good chance for another major flare in the next 24-48 hours.
The position of NOAA 11429 on 7-Mar-2012 at 08:00 UT is:
N17E24, ( -377", 388" )

Dear RHESSI Collaborators,
Solar activity remains high with NOAA 11429 continuing to produce high C-
and low M-class flares. The region appears to be undergoing new flux
emergence while retaining its delta configuration, which is due to negative
flux encroaching on the positive leader spot. Major Flare Watch conditions
remain: further intermediate level activity expected with chance for an
event larger than M5.
The position of NOAA 11429 on 6-Mar-2012 at 11:00 UT is:
N17E30, ( -467", 382" )

Dear RHESSI Collaborators,
The target region NOAA 11429 was the source of an X1.1 flare at 02:30 UT
today. At this time we are implementing a Major Flare Watch campaign. The
region has substantially increased in size and is now classified as a
beta-gamma-delta region. Further increased activity expected with chance
for another >M5 flare.
The position of NOAA 11429 on 5-Mar-2012 at 09:30 UT is:
N18E45, ( -653", 379" )

Dear RHESSI Collaborators,
The target region in the northeast quadrant, now designated NOAA 11429, was
the source of an M2.0 flare at 10:29 UT today as well as several C-class
events. The region has been classified as having a beta-gamma configuration
with a sunspot area of 290 uH. Further C-level activity expected with
chance for another M-class flare.
The position of NOAA 11429 on 4-Mar-2012 at 00:30 UT is:
N18E62, ( -813", 351" )

Dear RHESSI Collaborators,
Solar activity has increased significantly. A new region on the northeast
limb was the source of several C-class flares, as well as an M3.3 flare at
17:29 UT yesterday. This new target region is not yet numbered, and its
magnetic configuration is unclear, but further intermediate level activity
is expected with chance for another M-class flare.
The approximate position of the target region on 3-Mar-2012 at 09:30 UT is:
N18E85, ( -917", 306" )

Dear RHESSI Collaborators,
Solar activity remains low. NOAA 11423 was the source of a C3.3 flare at
15:10 UT yesterday. A new sunspot region has emerged within the decaying
plage of NOAA 11424, designated NOAA 11427, and has produced several
B-level events in the past 24 hours. NOAA 11427 shall be the new target
region and may produce further low-level activity if it continues to
develop.
The position of NOAA 11427 on 2-Mar-2012 at 10:30 UT is:
N15W11, ( 187", 365" )

Dear RHESSI Collaborators,
Solar activity continues at low levels. The decaying plage of NOAA 11424
was the source of a few low B-class flares since the last message. However,
alpha region NOAA 11423 shall remain the target region for a further 24
hours. No significant activity expected at this time.
The position of NOAA 11423 on 1-Mar-2012 at 12:30 UT is:
N17W22, ( 342", 390" )

Dear RHESSI Collaborators,
Solar activity remains low with no significant events over the past 24
hours. The target region shall revert back to NOAA 11423, the alpha region
located along the northern central meridian. The region has remained
unchanged in recent days and may only produce isolated, low-level events.
The position of NOAA 11423 on 29-Feb-2012 at 10:30 UT is:
N17W07, ( 121", 398" )

Dear RHESSI Collaborators,
Solar activity remains low. NOAA 11426 has continued to decay since the
last message. The unnumbered plage region in the northeast quadrant has
been the source of several B-class flares and shall be the new target
region. Further low-level events possible.
The position of the target region on 28-Feb-2012 at 10:30 UT is:
N09E33, ( -517", 252" )

Dear RHESSI Collaborators,
Solar activity is very low with flares coming from NOAA 11421 and the
occulted region on the south-east limb. Two new regions 11425 and 11426
have been named as the former plage region leading 11423/11424. There
appears to be some flux emergence occurring in this plage region which may
drive solar activity in the coming days. This region will become todays
target, although keeping nearby 11423/11424 in view may be prudent.
Activity is expected to remain at the B/C level for the next 24 hours.
The position of NOAA 11426 on 27-Feb-2012 14:00 UT is:
N10 E04, ( -66", 287" )
