Dear RHESSI Collaborators,
The level of solar activity is low. NOAA region 11149 has maintained its
area coverage but decreased in number of spots. This region has been
reclassified as a beta magnetic configuration, with these changes most
likely due to obscuration effects as the region approaches the NW limb.
B-class activity is expected, with a chance for an isolated C-class flare.
The position of NOAA 11149 on 25-Jan-2011 at 16:00 UT is:
N16W54, ( 757", 321" )

Dear RHESSI Collaborators,
Solar activity is at a low level. NOAA region 11149 continues to grow slowly
and remains a beta-gamma magnetic classification. In the past 24 hours this
region produced several B-class flares and a C1.4 event (on 24-Jan-2011 at
05:56 UT). Continued B-class activity is expected, with another C-class event
possible in the next 24 hours. A minor chance remains for an isolated M-class
event in the next few days if NOAA 11149 undergoes rapid flux emergence.
The position of NOAA 11149 on 24-Jan-2011 at 12:30 UT is:
N17W39, ( 586", 353" )

Dear RHESSI Collaborators,
NOAA 1149 continues in a slow growth phase maintaining its
beta-gamma magnetic configuration. 1149 was again the source
of minor B-class activity. B-class events expected with a possible
C-class event expected in the next 24 hours. There remains
a slight chance of an isolated M-class event in the next few days
if 1149 continues in growth phase.
The position of NOAA 1149 on January 23 at 16:00 UT is:
N24W31 (Solar X = 460", Solar Y = 467")

Dear RHESSI Collaborators,
NOAA 1149 was the source of several C-class events since
the last message. The largest was a C2.4 at 01/22/08:28 UT.
1149 is expected to produce C-class activity today with a slight
chance of an isolated M-class event within the next few days if
it continues in growth phase.
The position of NOAA 1149 on January 22 at 15:00 UT is:
N18W14 (Solar X = 225",Solar Y = 383")

Dear RHESSI Collaborators,
A strong EFR (NOAA 1149) located just south of NOAA 1147
was the source of several C-class events. The largest was a C3.3 at
01/21/04:14 UT. This flare event was observed in both 1149 and 1147.
1149 emerged late on January 20 and developed rapidly into a
complex beta-gamma magnetic configuration. C-class events
expected today with a slight chance of an isolated M-class
event if 1149 continues to develop.
The position of NOAA 1149 on January 21 at 15:45 UT is:
N19W01 (Solar X = 016", Solar Y = 400")

Dear RHESSI Collaborators,
NOAA 1147 is mostly unchanged. It continues to produce
minor B-class events. The largest was a B4.2 at
01/20/14:57 UT. 1147 is expected to continue
producing B-class events with a slight chance
of a isolated C-class event.
The position of NOAA 1147 on January 20 at 16:30 UT is:
N25E12 (Solar X = -184, Solar Y = 488")

Dear RHESSI Collaborators,
NOAA 1147 is mostly unchanged. There remains a chance of
B-class activity with only a very slight chance of an isolated
C-class event.

Dear RHESSI Collaborators,
NOAA 1147 added a few opposite polarity spots within its intermediate
portion. 1147 continues to be the source of B-class events. The
largest was a B5.9 at 01/17/21:51 UT. B-class activity is expected
to continue with a chance of a C-class event.
The position of NOAA 1147 on January 18 at 15:00 UT is:

Dear RHESSI Collaborators,
NOAA 1147 added a few trailing polarity spots but retains a simple
C-type/beta sunspot group. 1147 continues to produce numerous
B-class events. Additional B-class events expected with a slight
chance of an isolated C-class event today.
The position of NOAA 1147 on January 17 at 15:30 UT is:

Dear RHESSI Collaborators,
NOAA 1147 has been mostly quiet since east limb passage.
It was the source of several minor B-class events. The largest
was a B5.7 at 01/15/23:48. Its current magnetic configuration
appears to be a simple beta. 1147 still has the potential
to continue producing B-class events with a chance of a
C-class event.
The position of NOAA 1147 on January 16 at 18:30 UT is:
N24E69 (Solar X = -832", Solar Y = 421")
