Dear RHESSI Collaborators,
Solar activity continues at the low B-level with NOAA 11704 remaining the
only region of note on the visible hemisphere. The region has remained
quiescent and unchanged over the past 24 hours. A new region encroaching on
the eastern limb was the source of an occulted B3.5 flare at 15:27 UT
yesterday and shall be the new target region. Further low-to-intermediate
level activity possible as the region rotates on to the disk.
The approximate position of the target region on 27-Mar-2013 at 11:00 UT is:
N08E77, ( -929", 158" )

Dear RHESSI Collaborators,
Solar activity continues at the low B-level. A new emerging flux region in
the southern hemisphere has been designated as NOAA 11705 but has remained
quiescent. NOAA 11704 it now classified as a having a beta configuration
and shall remain the target region, although no significant increase in
activity is expected over the next 24 hours.
The position of NOAA 11704 on 26-Mar-2013 at 10:00 UT is:
N16E39, ( -583", 349" )

Dear RHESSI Collaborators,
Solar activity remains at the low B-level with the only notable event over
the past 24 hours being a long-duration B4.1 flare from NOAA 11704
beginning at 21:21 UT yesterday. The region is classified as having an
alpha configuration but has some trailing positive polarity plage. With
NOAA 11703 now over the western limb NOAA 11704 shall be the new target
region. No significant increase in activity expected at this time.
The position of NOAA 11704 on 25-Mar-2013 at 10:00 UT is:
N16E54, ( -748", 329" )

Dear RHESSI Collaborators,
The level of solar activity is very low. Yesterday's target has
been designated as NOAA region 11704, and classified by NOAA as
an alpha/H-type sunspot group. NOAA regions 11702 and 11703 have
shown signs of marginal growth in spot area and number of spots,
but none of the regions on disk have produced any flare activity
since yesterday's message. The target will switch to NOAA 11703
as it rotates toward the South West limb over the next 24 hours.
B-class activity is likely, with a small chance for an isolated
low C-class event.
The position of NOAA 11703 on 24-Mar-2013 at 13:00 UT is:
S25W79, ( 857", -384" )

Dear RHESSI Collaborators,
Solar activity is at a low level. NOAA region 11692 has now rotated
over the limb and lies completely beyond view. Yesterday's emerging
region has been designated as NOAA 11703 and assigned a beta/D-type
sunspot group classification by NOAA, but has remained quiet in the
past 24 hours. A new spotted region is rotating over the North East
limb. This region has a well developed leading spot, is bright in
chromospheric emission and large-scale coronal loops, and was the
source of a B6.8 flare on 23-Mar-2013 at 12:15 UT. Further B-class
activity is expected, with a small chance for a low C-class event.
The approximate position of this region on 23-Mar-2013 at 14:30 UT is:
N17E90, ( -920", 279" )

Dear RHESSI Collaborators,
Solar activity is at a moderate level. A new flux region is emerging in
the South West quadrant and has developed several spots in the previous
12 hours. NOAA region 11692 has rotated to the North West limb and was
last classified by NOAA as a beta/D-type sunspot group. This region was
the source of several low C-class events in the past 24 hours, as well
as an M1.6 on 21-Mar-2013 at 21:42 UT. Further low C-class activity is
likely with a small chance for another high C-/low M-class event before
the higher-lying loops of NOAA 11692 rotate completely beyond the limb.
The position of NOAA 11692 on 22-Mar-2013 at 14:30 UT is:
N09W90, ( 950", 150" )

Dear RHESSI Collaborators,
Solar activity is at a low level. NOAA region 11692 has continued
to emerge magnetic flux over the past 24 hours, primarily in front
of the main negative-polarity spot. This region has grown in both
spot area and number of spots, and remains classified by NOAA as a
beta/D-type sunspot group. NOAA 11692 has remained the most active
region since yesterday's message and produced the largest flare (a
C1.0 on 20-Mar-2013 at 19:26 UT). Further low C-class activity is
possible, with a very small chance for a high C-/low M-class event.
The position of NOAA 11692 on 21-Mar-2013 at 14:00 UT is:
N09W79, ( 933", 172" )

Dear RHESSI Collaborators,
Solar activity is at a low level. NOAA region 11698 was the source
of a foot-point occulted C5.5 flare on 20-Mar-2013 at 00:39 UT, but
has now rotated completely beyond the South West limb. NOAA region
11692 has emerged mixed-polarity flux along the leading edge of the
primary negative-polarity spot over the past 24 hours, and is now
designated by NOAA as a beta/D-type sunspot group. This region has
highly elongated penumbrae with indications of a beta-gamma magnetic
classification, and has produced several low C-class events in the
past 24 hours. Further low C-class activity is likely, with a small
chance for a high C-/low M-class event if NOAA 11692 emerges more
magnetic flux.
The position of NOAA 11692 on 20-Mar-2013 at 14:00 UT is:
N09W65, ( 862", 199" )

Dear RHESSI Collaborators,
Solar activity remains at a low level. NOAA 11698 has continued to
produce C-class activity in the past 24 hours, the largest being a
C4.3 flare on 19-Mar-2013 at 00:51 UT. This region is designated as
a beta/E-type sunspot group but has now rotated over the South West
limb, with a resulting decrease in the background X-ray flux. A new
positive-polarity spot has emerged in the past 12 hours in front of
the primary negative-polarity spot of NOAA 11692. This new magnetic
flux might destabilize the previously quiescent magnetic topology,
but the target will remain with the flare-productive NOAA 11698 as
its higher-lying loops will remain visible for the next 12-24 hours.
Further low C-class activity is possible, with a small chance for
an isolate high C-/low M-class event.
The position of NOAA 11698 on 19-Mar-2013 at 14:30 UT is:
S19W90, ( 911", -311" )

Dear RHESSI Collaborators,
Solar activity is at low-to-moderate levels. NOAA 11696 produced no flares
in the past 24 hours. This region has increased in number of spots, while
maintaining spot area and a beta-gamma/E-type sunspot group classification
by NOAA. However, mixed-polarity magnetic flux in the intermediate portion
of NOAA 11696 has decreased in magnitude over the past 12 hours. NOAA 11698
has grown in both spot area and number of spots as it approaches the limb,
and appears quite bright in chromospheric UV emission. This region has been
reclassified by NOAA as a beta/E-type sunspot group, and has continued to
produce low C-class events (the largest being a C2.8 flare on 18-Mar-2013
at 03:15 UT). Further low C-class activity is likely, with a small chance
for an isolated high C-/low M-class event.
The position of NOAA 11698 on 18-Mar-2013 at 14:00 UT is:
S19W80, ( 897", -291" )
