MM#003 Major Flare Watch
Dear RHESSI Collaborators,
Major Flare Watch target region, NOAA 2644, was the
source of two major events since the last message.
(M5.7 at 04/02/20:33 UT and an M5.8 at 04/03/14:29 UT).
2644 also produced a few lower-level M-class events
and numerous C-class events. 2644 remains in growth
phase maintaining its large and magnetically complex
F-type/beta-gamma-delta sunspot group. NOAA 2645,
S10W34, is also a large E-type/beta-gamma-delta region
but is currently not producing major flares. 2644 has the
potential to produce another major => M5 flare with a slight
chance of an X-class flare in the next 24 hour period.
The position of NOAA 2644 on April 03 at 13:30 UT is:
N12W73 (Solar X = 898", Solar Y = 228")

Dear RHESSI Collaborators,
Solar activity has increased dramatically. NOAA 12644 has produced two
mid M-class flares in the past 24 hours, with an M5.4 currently in
progress (07:50 UT). At this time we are issuing a Major Flare Watch
with NOAA 12644 as the target region. The region is approaching the
western limb and appears to be increasing in magnetic complexity.
Further intermediate level activity expected (from NOAA 12645 as
well), with chance for additional M-level activity in the next 24
hours.
The position of NOAA 12644 on 2-Apr-2017 at 07:30 UT is:
N12W56, ( 779", 257" )

Dear RHESSI Collaborators,
The target region NOAA 12645 was the source of two C1 flares, as well
as numerous B-class flares, since the last message. The region has
continued to develop and has regained its beta-gamma configuration due
to renewed flux emergence in its core. Good chance of further B- and
C-level activity over the next 24 hours.
The position of NOAA 12645 on 1-Apr-2017 at 07:30 UT is:
S10W03, ( 49", -58" )

Dear RHESSI Collaborators,
Solar activity continues at the B-level, with NOAA 12644 and NOAA
12645 remaining productive. However, while NOAA 12644 has remained
relatively stable over the past few days, NOAA 12645 has remained
dynamic and continues to grow in size, and shall therefore be the new
target region. Renewed flux emergence implies further B-level activity
over the next 24 hours, with chance for an isolated C-class flare.
The position of NOAA 12645 on 31-Mar-2017 at 07:30 UT is:
S10E12, ( -197", -59" )

Dear RHESSI Collaborators,
Solar activity continues at the B-level, with the largest event since
the last message being a B6.5 flare from the target region NOAA 12644
at 23:19 UT yesterday. Both the target region and NOAA 12645 are now
classified as beta regions, although NOAA 12645 still appears to be
undergoing dynamic flux emergence. Further B-level activity likely
from both regions.
The position of NOAA 12644 on 30-Mar-2017 at 07:30 UT is:
N12W13, ( 212", 305" )

Dear RHESSI Collaborators,
Solar activity remained at the B-level over the past 24 hours, with
events emanating primarily from NOAA 12645 and NOAA 12646, an alpha
region approaching the western limb. NOAA 12644 has lost some
complexity as it crosses the central meridian and is now classified as
a beta region. NOAA 12644 shall remain the target region, with B-level
activity expected from both it and NOAA 12645.
The position of NOAA 12644 on 29-Mar-2017 at 07:30 UT is:
N12W00, ( 0", 308" )

Dear RHESSI Collaborators,
Solar activity has increased significantly since the last message,
with B- and C-class flares emanating from both NOAA 12644 and NOAA
12645. The largest event was a C5.1 flare from NOAA 12645 at 17:55 UT
yesterday. Both regions have a beta-gamma configuration, although NOAA
12645 continues to undergo flux emergence. NOAA 12644 shall continue
to be the target region but keep NOAA 12645 in your field of view as
well if possible. Further C-level activity likely from both regions.
The position of NOAA 12644 on 28-Mar-2017 at 07:30 UT is:
N13E13, ( -211", 322" )

Dear RHESSI Collaborators,
The target region in the northeast quadrant has now been designated as
NOAA 12644, and is classified as a beta/D-type region. The region has
produced several B-class flares since the last message, as well as a
C1 flare around 00:00 UT today. Note that the C3.2 flare currently in
progress (11:07 UT) is from another newly emerging region towards the
southeast. NOAA 12644 shall continue to be the target region with
further B- and C-level activity likely.
The position of NOAA 12644 on 27-Mar-2017 at 07:30 UT is:
N12E26, ( -413", 299" )

Dear RHESSI Collaborators,
NOAA 12643 has remained quiescent since the last message. In the
meantime, a new beta region has emerged to the east. The currently
unnumbered region has produced several B-class flares, including a
B4.0 at 02:29 UT today, and shall be the new target region. Further
B-level activity possible.
The position of the target region on 26-Mar-2017 at 07:30 is:
N13E41, ( -619", 299" )

Dear RHESSI Collaborators,
Solar activity continues at very low levels. NOAA 12643 has remained
quiescent and appears to be in decay. It shall continue to be the
target region although no significant activity is expected over the
next 24 hours.
The position of NOAA 12643 on 25-Mar-2017 at 08:30 UT is:
N08E24, ( -388", 237" )
