Dear RHESSI Collaborators,
The level of solar activity is extremely low. NOAA regions 12641 and
12642 have continued to decay over the past 24 hours, both decreasing
in spot size while losing all penumbra on their leading and trailing
spots. These two regions are now both classed as beta/B-type sunspot
groups, with 12641 producing two B1.7 flares since the last message.
Further low B-class flares may be possible in the next 24 hours.
The position of NOAA 12641 on 3-Mar-2017 at 20:00 UT is:
N15W07, ( 114", 367" )

Dear RHESSI Collaborators,
Solar activity is at an extremely low level. The leading spot pair of
NOAA 12641 has now been designated as a separate region, NOAA 12642.
NOAA 12641 has decreased in spot area over the past 24 hours while it
has gained penumbra to be classified as a beta/C-type sunspot group.
The only flaring activity observed since the last message was a B1.2
on 2-Mar-2017 at 01:16 UT that originated from a small region that is
rotating over the North East limb. Low B-class flares may be possible
in the following 24-hour period.
The position of NOAA 12641 on 2-Mar-2017 at 22:00 UT is:
N14E07, ( -113", 351" )

Dear RHESSI Collaborators,
The level of solar activity is very low. NOAA 12641 has grown in both
spot area and number of spots over the previous 24 hours, maintaining
a beta/C-type sunspot group classification. This region continued to
be the source of B-class activity by producing 5 B-class events since
the last message, including the largest flare of the period (a B2.8
on 1-Mar-2017 at 07:57 UT). More B-class flares are expected over the
next 24 hours.
The position of NOAA 12641 on 1-Mar-2017 at 21:30 UT is:
N15E14, ( -230", 364" )

Dear RHESSI Collaborators,
Solar activity is at a very low level. The newly spotted region in the
North East quadrant is now numbered NOAA 12641. This region has been
designated as a beta/C-type sunspot group classification and displays
a double bipole magnetic structure. NOAA 12641 has been the source of
six B-class events over the past 24 hours, including the largest flare
within the period (a B9.3 on 27-Feb-2017 at 20:07 UT). Further B-class
activity is expected over the following 24-hour period.
The position of NOAA 12641 on 28-Feb-2017 at 20:00 UT is:
N15E35, ( -538", 346" )

MM#009 Default HESSI Target
Dear RHESSI Collaborators,
NOAA 2638 continues to decay and continues to be
quiescent. There were no events in the past two days.
2638 is currently displaying only a single round sunspot.
No significant solar flare activity expected in the next
24 hour period.
The position of NOAA 2638 on February 26 at 07:30 UT is:
N17W06 (Solar X = 097", Solar Y = 398")

MM#009 Default HESSI Target
Dear RHESSI Collaborators,
NOAA 2638 is mostly unchanged and is currently much
less dynamic today. B-class activity is still possible with
the chance of a C-class event less likely in the next 24
hour period.
The position of NOAA 2638 on February 25 at 08:00 UT is:
N17E07 (Solar X = -113", Solar Y = 398")

MM#009 Default HESSI Target
Dear RHESSI Collaborators,
NOAA 2638 produced two C-class events in the past
24 hours. The largest was a C1.3 at 02/23/20:53 UT.
2638 has significantly decayed since the last message.
B-class events possible with a slight chance of another
C-class event in the next 24 hour period.
The position of NOAA 2638 on February 24 at 14:30 UT is:
N18E15 (Solar X = -240", Solar Y = 410")

MM#009 Default HESSI Target
Dear RHESSI Collaborators,
NOAA 2638 continues to slowly decay especially within
its northern portion. 2638 was the source of minor B-Class
activity in the past 24 hours. Additional B-class events
probable with the chance of an isolated C-class event in
the next 24 hour period.

at 02/22/13:27 UT. 2638 has decayed, losing sunspot
area within its northern portion but is maintaining weak
mixed polarities. B-class events expected with the
chance of another C-class event in the next 24 hours.

Dear RHESSI Collaborators,
Target region NOAA 2638 is mostly unchanged maintaining
