MM#003 Major Flare Watch
Dear RHESSI Collaborators,
Solar activity is high. Following the previously reported M5 flare on
2011/09/06 01:40 UT, NOAA 11283 was the source of an X2.1 proton
(>10MeV) event at 22:20 UT. The event was associated with an Earth
directed CME and caused an R3 radio blackout. The region continues to
evolve and is now classified as a beta-gamma-delta type. The sunspots
within the AR are rapidly converging on each other to the west of the
region, most likely driving the high level activity we are getting.
The Major Flare Watch campaign will continue as further high level
activity is probable with further >=M5 flares possible in the next 24
hours.
The position of NOAA 11283Â on 7-Sep-2011 15:30 UT is:
N14W27 ( 417", 125" )

MM#003 Major Flare Watch
Dear RHESSI Collaborators,
At this time we are implementing Max Millennium coordinated
observing plan #003 (Region Likely To Produce A Major Flare).
NOAA 1283 switched into rapid growth phase developing a
complex magnetic delta configuration. 1283 was the source
of a major M5.3 flare at 01:50 UT today. A fast Earth-directed
CME was associated with the flare. It is possible that
1283 will produce another event =>M5 in the next few days.
The position of NOAA 1283 on September 06 at 15:30 UT is:
N14W13 (Solar X = 208", Solar Y = 115")

MM#009 Default HESSI Target
Dear RHESSI Collaborators,
Target NOAA 1280 located beyond the northwest limb was the
source of two M-class events since the last report
(M1.6 at 09/05/04:28 and M1.2 at 09/05/07:58 UT).
Additional interesting limb events are possible for at least during
the first half of the next 24 hour period.
The position of NOAA 1280 on September 05 at 15:30 UT is:
N13W91 (Solar X = 926", Solar Y = 214")

MM#009 Default HESSI Target
Dear RHESSI Collaborators,
West limb target region NOAA 1280 was the source of several C-class
events and an impressive M3.2 event since the last message.
The M-class event was at 09/04/11:45 UT. 1280 should produce
additional limb events in the next 24 hour period.
The position of NOAA 1280 on September 04 at 04:30 UT is:
N12W81 (Solar X = 919", Solar Y = 177")

MM#009 Default HESSI Target
Dear RHESSI Collaborators,
Target region, NOAA 1281, was the source of a C2.4 event
at 09/03/07:56 UT. 1281 has significantly decayed since the
last message. NOAA 1283 (N13E28) developed slightly
but continues quiescent. NOAA 1280 (N11W75) also
added new flux and is the brightest region in H-alpha
on the visible disk. 1280 produced two C1.0 events
today at 03:22 and 14:12 UT. 1280, 1281 and 1283 have
beta magnetic configurations. The target will switch from
1281 to 1280 today. Another C-class event is possible
in the next 24 hour period.
The position of NOAA 1280 on September 03 at 15:30 UT is:
N11W75 (Solar X = 902", Solar Y = 149")

MM#009 Default HESSI Target
Dear RHESSI Collaborators,
Solar flare activity remains low. The largest event in the past
24 hour period was a C1.8 at 09/02/15:15 UT. The
source region for this event was target region NOAA 1281.
Both 1281 and 1283 (N12E40) are capable of producing
C-class events in the next 24 hour period.
The position of NOAA 1281 on September 02 at 15:30 UT is:
S21E03 (Solar X = -046", Solar Y = -450")

MM#009 Default HESSI Target
Dear RHESSI Collaborators,
Target region, NOAA 1281, added a few more spots and increased
magnetic complexity slightly. Its sunspot group is currently classified
D-type/beta-gamma. The largest event in the past 24 hour period
was a C2.0 at 09/01/12:45 UT produced by NOAA 1283 (N12E52).
Both 1281 and 1283 should produce additional C-class events with
even a very slight chance of an isolated M-class event in the next few days.
The position of NOAA 1281 on September 01 at 15:30 UT is:
S20E19 (Solar X = -291", Solar Y = -429")

MM#009 Default HESSI Target
Dear RHESSI Collaborators,
The target region, now numbered NOAA 1283 (N12E62), was the
source of a C2.2 event at 08/31/13:22 UT. The largest event in the
past 24 hours was produced by NOAA 1281. New flux
rapidly emerged in the trailing portion of the region overnight.
1281 currently has a D-type/beta sunspot group.
The target will switch from 1283 to 1281 for at least the next
24 hour period. Another C-class event is possible.
The position of NOAA 1281 on August 31 at 15:30 UT is:
S20E31 (Solar X = -461", Solar Y = -419")

MM#009 Default HESSI Target
Dear RHESSI Collaborators,
The target region has partially rotated over the northeast limb.
It is too close to the limb to fully ascertain its magnetic classification
but it appears to have a simple beta configuration. B-class
events are probable with a C-class event possible within the next
24 hour period.
The position of the target region on August 30 at 15:00 UT is:
N14E85 (Solar X = -919", Solar Y = 218")

MM#009 Default HESSI Target
Dear RHESSI Collaborators,
All regions on the visible solar disk are currently decaying or
stable and are quiescent. There is an active region located beyond
the northeast limb that has been the source of C-class activity
today.The largest was a C3.7 at 08/29/07:21 UT. Additional
C-class events expected during the next 24 hour period.
The approximate position of the target on August 29 at 08:00 UT is:
N14E90 (Solar X = -922", Solar Y = 228")
