Dear Collaborators,
Solar activity continues at a low level. The target region has been
numbered as NOAA 12978 with an alpha/H-type configuration. It
was the source of a few low C-class flares (including the largest one,
a C4.1 at 03/27/23:54 UT). Another region NOAA 12975 (beta/C-type)
also produced two ~C1 flares during the period. The leading polarity
of the target region is emerging magnetic fluxes. Additional C-class
activities are expected in the next 24 hours.
The position of NOAA 12978 on March 28 at 03:30 UT is:
S15E73 (-888", -215")

Dear Collaborators,
The level of solar activity is low. The target region has begun to
rotate onto the visible disk, showing a reasonably-sized leading
polarity spot with potentially an additional leading polarity spot
slightly behind and to the South. Of the numbered spot regions on
the visible disk, only NOAA 12975 produced a flare since the last
message (and that was a B9.7), while the target region continued
producing C-class activity (three in total, including the largest
of the period in a C2.4 on 27-Mar-2022 at 10:37 UT). More C-class
activity is expected over the following 24-hour period.
The approximate position of this region on 27-Mar-2022 at 16:30 UT is:
S17E87 , ( -918", -273" )

Dear Collaborators,
Solar activity is at a low level. Target region NOAA 12976 has not
evolved significantly since the last message and is now classified
as a beta/E-type sunspot group. None of the sunspot regions on the
visible disk have produced flares since the last message, while a
region currently beyond the South East limb was responsible for a
B8.5 and a C2.3 on 26-Mar-2022 at 14:14 and 15:81 UT, respectively.
The target changes to this South East limb region. C-class flares
are probable in the next 24 hours.
The approximate position of this region on 26-Mar-2022 at 18:00 UT is:
S21E90 , ( -898", -342" )

Dear Collaborators,
The level of solar activity is moderate. The target region has now
been separately numbered as NOAA 12976 and is confirmed as a beta/
D-type sunspot group. This region has continued to produce B-class
flares and a C2.6 on 25-Mar-2022 at 02:27 UT. The largest flare of
the period instead came from NOAA 12974 - a M1.4 on 25-Mar-2022 at
05:02 UT, with a corresponding CME. However, the target will stay
with NOAA 12976 due to 12975 being in an advanced stage of decay.
Additional C-class flares are expected over the following 24-hour
period.
The position of NOAA 12976 on 25-Mar-2022 at 22:00 UT is:
N15E52 , ( -733", 316" )

Dear Collaborators,
Solar activity is at a low level. The target region has now rotated onto
the visible disk and displays leading and trailing sunspots with mature
penumbrae on each. Rather than being independently numbered, these large
sunspots have been grouped together under the designation of NOAA 12975
along with the smaller sunspots that rotated on disk ahead of them. NOAA
12975 has been the source of eight C-class flares since the last message,
including the largest flare of the period (a C8.1 on 24-Mar-2022 at 01:42
UT), but on inspection all of these originate from the trailing, larger
pair of sunspots. The target region focuses on these more Eastern spots
in NOAA 12975. Further C-class activity is expected in the next 24 hours.
The target position within NOAA 12975 on 24-Mar-2022 at 22:30 UT is:
N13E61 , ( -822", 270" )

Dear Collaborators,
The level of solar activity is low. The target region has now rotated onto
the visible disk and, although it shows leading and trailing sunspots both
with penumbrae (potentially a beta/D-type classification), it has remained
unnumbered at the beginning of the UT day. An additional region containing
larger sunspots is rotating over the North East limb just slightly behind
yesterday's target region. Several of the flares associated to yesterday's
target region may have actually come from the new limb-crossing region and
it has clearly produced several C-class flares since the last message. The
target region switches to the newer (and larger) spot region rotating over
the North East limb. Further C-class flaring is expected over the following
24-hour period.
The approximate position of this region on 23-Mar-2022 at 23:00 UT is:
N13E85 , ( -924", 235" )

Dear Collaborators,
Solar activity is at a low level. The target region has now rotated
fully onto the visible disk and shows some small sunspots, but was
unnumbered at the start of the UT day. This region appears to have a
beta/C-type sunspot group classification and has continued to be the
source of B-class flares and a C1.2 flare on 22-Mar-2022 at 10:57 UT.
However, the largest flare of the period was a C7.0 on 22-Mar-2022 at
12:15 UT from a new small sunspot region rotating over the North East
limb (that also produced a C1.0 on 22-Mar-2022 at 04:07 UT). The MMCO
target region switches to the North East limb region, for at least 24
hours until its longitudinal extent and magnetic configuration is
better observed. Additional C-class activity is probable in the next
24 hours.
The approximate position of this region on 22-Mar-2022 at 18:00 UT is:
N13E90 , ( -938", 215" )

Dear Collaborators,
The level of solar activity is very low. Target region NOAA 12965 has
now fully rotated over the North West limb. The plage region that was
previously designated as NOAA 12971 has undergone some flux emergence
and is consolidating flux into two small opposite-polarity spots, and
was the source of mid-B-class flares since the last message. The most
flare-productive region is a new spot region rotating over the South
East limb that has produced several footpoint occulted B-class flares
as well as the largest flare of the period (a C1.2 on 20-Mar-2022 at
18:04 UT). Further B-class activity is expected, with a good chance
for mid-/high- C-class activity over the following 24-hour period.
The approximate position of this region on 21-Mar-2022 at 18:00 UT is:
S18E90 , ( -916", -295" )

Dear Collaborators,
Solar activity continues to be at a very low level. The largest event
in the past 24 hours was a C4.6 at 03/20/07:30 UT produced by
NOAA 12971 that just re-emerged some tiny spots. Target region
NOAA 12965 has decayed to a beta/C-type configuration and is
rotating beyond the west limb. It was the source of a C2.1 flare and
also a few B-class flares. Additional C-class activities are probably
in the next 24 hours.
The position of NOAA 12965 on March 20 at 08:30 UT is:
N26W73 (828", 450")

Dear Collaborators,
Solar activity remains at a very low level. The largest event in the
past 24 hours was a C1.3 flare at 03/19/03:49 UT produced by
target region NOAA 12965. 12965 also produced seven B-class
flares during the period. It retains a beta/F-type configuration but
decays further. Additional C-class activities are expected with a
slight chance of a low M-class flare when 12965 rotates over the
west limb.
The position of NOAA 12965 on March 19 at 08:30 UT is:
N25W60 (757", 458")
