Dear Collaborators,
Solar activity remains at an extremely low level, with the background
soft X-ray flux close to the A1.0 level. The target region NOAA 12813
has remained stable in terms of sunspot area since the last message,
continuing to be classed as an alpha/A-type sunspot group. NOAA 12813
will remain the target for the following 24-hour period as it rotates
up to the North West limb. A-class flaring activity is probable over
the next 24 hours.
The position of NOAA 12813 on 6-Apr-2021 at 18:30 UT is:
N20W60 , ( 781", 375" )

Dear Collaborators,
The level of solar activity continues to be extremely low. The target
region was designated as NOAA 12813 after the last message was sent,
and was classified as an alpha/A-type sunspot group. This region has
decayed over the past 24 hours and has produced low A-class activity.
NOAA 12813 will remain the target for the next 24 hours as it rotates
towards the North West limb. More A-class activity is expected in the
following 24-hour period.
The position of NOAA 12813 on 5-Apr-2021 at 15:00 UT is:
N21W45 , ( 635", 412" )

Dear Collaborators,
Solar activity has remained at the low A-level since the last message,
with events from both the target region in the northwest quadrant and
NOAA 12812 from behind the northwest limb. The target region remains
unnumbered and has shown signs of decay in its trailing spot. Chance
for additional A-level activity over the next 24 hours.
The approximate position of the target region on 4-Apr-2021 at 15:30 UT is:
N20W31, ( 471", 412" )

Dear Collaborators,
Solar activity has remained at very low levels, with NOAA 12812 now
behind the western limb. A newly-emerged region in the northwest
quadrant has produced a series of A-class flares since the last
message and shall be the new target region. The region has a clear
beta configuration but is currently unnumbered. Chance for increased
activity over the next 24 hours if the region continues to develop.
The approximate position of the target region on 3-Apr-2021 15:30 UT is:
N19W17, ( 266", 409" )

Dear Collaborators,
Solar activity has remained at the A-level since the last message,
with NOAA 12812 producing an A7.7 flare at 06:17 UT today. The solar
disk remains spotless with both NOAA 12812 and 12811 now on the
northwest limb. NOAA 12812 shall continue to be the target region with
chance for an additional isolated low-level event before west limb
passage.
The position of NOAA 12812 on 2-Apr-2021 at 15:30 UT is:
N23W73, ( 845", 401" )

Dear Collaborators,
The visible solar disk is now spotless with the decaying plage of both
NOAA 12811 and 12812 approaching the western limb. NOAA 12812 has
produced a series of low A-class flares since the last message and
shall remain the target region. No change in activity expected over
the next 24 hours. Also include NOAA 12811 in your field of view, if
possible, before west limb passage.
The position of NOAA 12812 on 1-Apr-2021 at 11:30 UT is:
N23W57, ( 742", 428" )

Dear Collaborators,
NOAA 12811 was the source of a B7.4 flare at 19:46 UT yesterday, which
preceded the large prominence eruption off the northwest limb. NOAA
12812 is now spotless and continues to decay. It shall remain the
target region with no significant change in activity expected over the
next 24 hours. Also include NOAA 12811 in your field of view if
possible as it rotates towards the western limb.
The position of NOAA 12812 on 31-Mar-2021 at 11:30 UT is:
N23W43, ( 604", 447" )

Dear Collaborators,
Solar activity has remained at background levels since the last
message. NOAA 12812 has remained quiescent and continues to decay. It
shall be the target region for another 24 hours although no activity
expected at this time. Please also include NOAA 12811 in your field of
view if possible.
The position of NOAA 12812 on 30-Mar-2021 at 15:30 UT is:

Dear Collaborators,
Solar activity continues at very low levels with A-class flares from
both NOAA 12811 and 12812 since the last message. NOAA 12812 retains
its alpha configuration but continues to decay. It shall remain the
target region but also include NOAA 12811 in your field of view if
possible. Only A-level activity expected over the next 24 hours.
The position of NOAA 12812 on 29-Mar-2021 at 11:30 UT is:
N21W19, ( 293", 442" )

Dear Collaborators,
The largest X-ray event in the past 24 hours was a B1.2 flare
(also the only B-class flare) at 03/27/20:34 UT produced by the
target region NOAA 12812. 12812 remains its alpha/H-type
configuration and now is the only region with sunspots on the
visible solar disk. Although NOAA 12811 decays to a plage region,
its coronal loops interact with the ones from 12812. If possible,
please include both regions in your field of view. Only very low
level activities are expected in the next 24 hours.
The position of NOAA 12812 on March 28 at 03:30 UT is:
N21W01 (15", 449")
