Dear Collaborators,
The target region NOAA 12811 has produced seven ~B1
flares since the last message, the largest one being a B1.7
at 03/24/04:01 UT. 12811 now has a beta/C-type configuration,
increasing in its sunspot area and number of spots. The
region near 12811 has been designated as NOAA 12812
(N21E50) with an alpha/H-type classification. If possible,
please also include 12812 in your field of view. More B-class
activities are expected over the next 24 hours.
The position of NOAA 12811 on March 24 at 04:30 UT is:
N19E30 (-456", 407")

Dear Collaborators,
The target region NOAA 12811 has produced three ~B1 flares since
the last message, the largest one being a B1.8 at 03/22/20:33 UT.
12811 remains its beta/B-type configuration, with slightly increasing
in its sunspot area. Near 12811 there is another region (N20E64,
unnumbered yet) showing some spots. If possible, please also include
this region in your field of view. Low B-class activities are expected
in the next 24 hours.
The position of the target NOAA 12811 on March 23 at 12:30 UT is:
N20E40 (-582", 411")

Dear Collaborators,
The largest X-ray event in the past 24 hours was a B5.6 flare
produced by NOAA 12810 (N18W04) at 03/22/01:10 UT. 12810
was the target region in previous days but now has decayed to
a plage region. The new target region near the northeast limb
has been designated as NOAA 12811 today and has a beta/
B-type configuration. 12811 produced three ~B1 flares in the
past 24 hours. Further B-class activities are expected over the
next 24 hours.
The position of the target NOAA 12811 on March 22 at 04:30 UT is:
N21E55 (-737", 405")

Dear Collaborators,
Yesterday's target region NOAA 12810 (N18E08) produced a B1.3 flare
over the past 24 hours. 12810 has decayed to an alpha/A-type region
and seems to lose all its spots now. Today the target will switch to the
northeast limb region as mentioned in the last message. This region has
produced three low B-class flares, the largest one being a B2.1 at 03/20/
15:31 UT. Additional low B-class activities are likely in the next 24 hours.
The approximate position of the target on March 21 at 08:30 UT is:
N21E73 (-820", 410")

Dear Collaborators,
Solar activity continues at a very low level and the GOES soft X-ray flux
remains below B1. The target region NOAA 12810 retains its alpha/H-type
configuration and only shows some tiny EUV jets. We will watch this region
for a further 24 hours. There emerged a new region from the northeast limb
(N20E87), which has produced a few A-class flares. Only low activities are
possible over the next 24 hours.
The position of NOAA 12810 on March 20 at 04:30 UT is:
N18E23 (-359", 400")

Dear Collaborators,
Solar activity continues at a very low level with the soft X-ray flux
flat at ~A4. Yesterday's plage target NOAA 12808 (N19W49) decays
further and is rotating near the west limb. Today the target region
will switch to NOAA 12810, the only region with sunspots on the
visible solar disk. 12810 remains its alpha/H-type configuration and
holds a small filament. No significant activities are expected in the
following 24 hours.
The position of NOAA 12810 on March 19 at 04:30 UT is:
N17E35 (-530", 373")

Dear Collaborators,
Solar activity has been at a very low level with the GOES soft X-ray
flux below B1. The target region NOAA 12808 has decayed to a plage
region and only shows some small EUV jets. We will watch this region
for a further 24 hours. NOAA 12810 (N18E47) is the only region with
sunspots on the visible solar disk now, which remains its alpha/H-type
configuration. Only very low activities are likely over the next 24 hours.
The position of NOAA 12808 on March 18 at 08:30 UT is:
N19W37 (550", 402")

Dear Collaborators,
The target region NOAA 12808 produced an isolated B3.2 flare
at 03/16/20:09 UT. 12808 remains its alpha/A-type configuration,
while showing some signs of flux emergence followed by cancellation
in both of its leading and trailing portions. The new region mentioned
in the last message was designated as NOAA 12810 (N17E57), having
an alpha/H-type configuration. Only low activities are expected in
the following 24 hours.
The position of NOAA 12808 on March 17 at 12:30 UT is:
N19W26 (400", 414")

Dear Collaborators,
Solar activity has been at a very low level with the soft X-ray flux flat
at ~A4 since the isolated B3 flare. The target region NOAA 12808
remains its Alpha/A-type configuration and only shows some small
EUV jets around its trailing portion. We will watch this region for a
further 24 hours. A new region at the northeast limb is rotating onto
the visible solar disk, which seems to show some tiny spots. Only low
activities are likely over the next 24 hours.
The position of NOAA 12808 on March 16 at 04:30 UT is:

Dear Collaborators,
The target region NOAA 12808 produced an isolated B3.0 flare
at 03/15/09:55 UT. 12808 further decays and has an alpha/H-type
configuration. Only low level activities are possible in the next 24
hour period.
The position of NOAA 12808 on March 15 at 20:30 UT is:
