MM#009 Default HESSI Target
Dear RHESSI Collaborators,
The most interesting solar activity since the last message
was a filament eruption/two-ribbon flare with an associated
C9.2 x-ray event at 05/13/18:18 UT. The filament was located
just east of the trailing portion of NOAA 2339 at approximately
N15W18. Target region 2339 continues to slowly decay but is
maintaining its F-type/beta-gamma classification. C-class
activity is probable with only a slight chance of an isolated
M-class event in the next 24 hour period.
The position of NOAA 2339 on May 14 at 11:35 UT is:
N13W41 (Solar X = 608", Solar Y = 247")

MM#009 Default HESSI Target
Dear RHESSI Collaborators,
Target region NOAA 2339 continues in decay phase but is
maintaining an F-type sunspot group with a beta-gamma
magnetic configuration. 2339 was the source of numerous
low-level C-class events in the past 24 hours. The largest was
a C3.2 at 05/13/11:11 UT. 2339 will produce C-class events
along with the possibility of an isolated M-class event in the
next 24 hour period. NOAA 2342, N18E13, has new flux
emergence with mixed polarities and could become the next
target region if development continues.
The position of NOAA 2339 on May 13 at 15:35 UT is:
N14W28 (Solar X = 434", Solar Y = 271")

MM#009 Default HESSI Target
Dear RHESSI Collaborators,
Target region NOAA 2339 has decayed somewhat especially
within the trailing portion but is still a large F-type/beta-gamma
region. 2339 was the source of C-class activity in the past 24 hours.
C-class events expected with the chance of an isolated
M-class event in the next 24 hours.
The position of NOAA 2339 on May 12 at 11:30 UT is:
N13W12 (Solar X = 193", Solar Y = 261")

MM#009 Default HESSI Target
Dear RHESSI Collaborators,
Target region NOAA 2339 is mostly unchanged maintaining
its very large F-type/beta-gamma sunspot group. The magnetic
complexity is located within the trailing portion at N13E04.
2339 was the source of C-class activity in the past 24 hours.
The most interesting event since the last massage was a filament
eruption and flare located along the magnetic inversion line between
NOAA regions 2342 and 2343. The eruption was associated
with a C2.5 x-ray event at 04:09 UT. NOAA 2339 will continue to
produce C-class activity with an M-class event possible in the
next 24 hour period. A major flare is also possible but less likely
today.
The position of NOAA 2339 on May 11 at 15:35 UT is:
N13W01 (Solar X = 016", Solar Y = 264")

Dear RHESSI Collaborators,
The level of solar activity is low. NOAA region 12339 has displayed
some initial signs of entering decay phase, decreasing in spot area
while increasing in number of spots. The intermediate spots of NOAA
12339 have shown the beginnings of decay the most, but this region
has maintained a beta-gamma/F-type sunspot group designation. 12339
has remained the most flare-productive region, being the source of
5 C-class events since yesterday’s message. The MM#003 Major Flare
Watch will continue for a final 24 hours as this region retains the
potential for another isolated flare above the M5 level.
The position of NOAA 12339 on 10-May-2015 at 23:00 UT is:
N12E11, ( -183”, 249” )

Dear RHESSI Collaborators,
Solar activity continues at a low level. NOAA 12339 has undergone further
growth over the past 24 hours, increasing in both spot area and number of
spots. 12339 has continued to maintain a beta-gamma/F-type sunspot group
classification and is the most flare-productive region, being the source
of 4 C-class events since yesterday’s message. The Major Flare Watch will
continue for another 24 hours as the recent flux emergence indicates that
this region retains the potential for another flare above the M5 level.
The position of NOAA 12339 on 9-May-2015 at 21:30 UT is:
N13E23, ( -365", 263" )

Dear RHESSI Collaborators,
The level of solar activity continues to be low. NOAA region 12339 has
grown further over the past 24 hours, increasing in both spot area and
number of spots. This region has maintained a beta-gamma/F-type sunspot
group classification. NOAA 12339 has produced 7 C-class events since
yesterday’s message, including the largest flare of the period (a C5.5
on 8-May-2015 at 03:56 UT). The Major Flare Watch will continue for 24
hours as this region retains the potential for another flare above the
M5 level.
The position of NOAA 12339 on 8-May-2015 at 16:00 UT is:
N13E38, ( -574”, 258” )

Dear RHESSI Collaborators,
Solar activity has returned to a low level. NOAA region 12339 has continued
to produce low-level flaring activity after the X2.7 flare on 5-May-2015 at
22:05 UT. This region has now been the source of 5 C-class events since the
MM#003 Major Flare Watch commenced yesterday, including the largest flare of
the period (a C4.3 on 7-May-2015 at 09:54 UT). NOAA 12339 is classified as a
beta-gamma/F-type sunspot group, appearing to have emerged new magnetic flux
over the past 24 hours. The Major Flare Watch will continue for 24-48 hours
as this region retains the potential for more flaring above the M5 level.
The position of NOAA 12339 on 7-May-2015 at 16:00 UT is:
N12E50, ( -716", 235" )

Dear RHESSI Collaborators,
Solar activity has increased significantly. The new region on the
northeast limb was the source of an X2.7 flare at 22:05 UT yesterday
and has been designated as NOAA 12339. The region appears to have a
beta-gamma-delta/E-type configuration and is showing signs of negative
polarity flux emergence within the positive core of the region. At
this time we are implementing a Major Flare Watch campaign due to the
increased probability of additional flaring greater than the M5 level.
The position of NOAA 12339 on 6-May-2015 at 19:35 UT is:
N12E58, ( -790", 228" )

Dear RHESSI Collaborators,
The level of solar activity is moderate. A new region that is rotating
over the North East limb has been the source of two low M-class events
(an M1.9 and an M1.2), but remains too close to the limb to accurately
determine its magnetic classification. NOAA 12335 has also produced an
M1.3 event in addition to the largest magnitude event since yesterday’s
message (an M2.6 flare on 5-May-2015 at 17:12 UT). 12335 has continued
to emerge new flux and is now classified as a beta-gamma/E-type sunspot
group. Further C-class activity is expected in the next 24 hour period,
with a good chance for additional low M-class flares.
The position of NOAA 12335 on 5-May-2015 at 22:00 UT is:
S15E12, ( -190", -188" )
