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" )

Dear RHESSI Collaborators,
Solar activity is very low. There was a single C class flare that
originated from the decaying plage of 11421. There appears to be a small
amount of emerging flux appearing in the center of this plage region. If
this continues to grow, it may produce further activity. However, today's
target will continue to be the regions in the north east quadrant. 11423
currently contains the largest spot on the Sun and although 11424 is more
decayed than anticipated, it has been producing multiple B class flares and
this is expected to continue. This will continue as today's target,
hopefully keeping 11423 in the target field also.
The position of NOAA 11424 on 26-Feb-2012 16:00 UT is:
N08 E42, ( -643" 223" )

Dear RHESSI Collaborators,
Solar activity remains low with only B class flares being produced. The
newly numbered NOAA 11424 has rotated onto the eastern limb and is bright
in EUV, X-rays and H-alpha. It is too close to the limb to determine its
magnetic complexity as yet, however it has been the most flare productive
region over the past number of days and it it expected to remain so. As
such, it will continue as today's target. B - C class activity is expected.
The position of NOAA 11424 on 25-Feb-2012 14:00 UT is:
N09E60, ( -830", 210" )

Dear RHESSI Collaborators,
Solar activity continues at very low levels. There have been no events >B
class in the past 24 hours. A new region - NOAA 11423 as rotated onto the
east limb, slightly north of the most recent target. This AR is small and
magnetically simple. The larger AR that remains occulted on the east limb
appears to consist of large loop structures with well defined footpoints
that are is bright in EUV and H-alpha. This region will remain the target
for the next 24 hours. B class activity is expected to continue.
The position of the target region on 24-Feb-2012 17:00 UT is:
N10E85, (-952", 170")

Dear RHESSI Collaborators,
The level of solar activity is very low. NOAA region 11422 appears to be
in decay phase. This region has decreased in area and number of spots as
well as flare productivity. A new region has rotated over the North East
limb, marking the return of the region previously designated NOAA 11415.
This region produced C-class activity when it emerged close to the North
West limb on the last disk passage, and has already produced an occulted
B4.3 flare on 21-Feb-2012 at 21:53 UT. B-class events are expected, with
a chance for a C-class event in the next 24 hours.
The approximate position of this region on 23-Feb-2012 at 11:00 UT is:
N10E88, ( -954", 171" )
