Dear Collaborators,
The past 24 hours has seen a resurgence of C-level activity from NOAA
13288, which is now beyond the southwest limb. NOAA 13293 has shown
significant signs of decay, while NOAA 13296 has continued to develop
and was the source of an M2.1 flare at 07:30 UT today. NOAA 13296
retains its anti-Hale beta/D-type configuration and shall be the new
target region, although we shall end the Major Flare Watch campaign at
this time. Further low M-class flares possible over the weekend.
The position of NOAA 13296 on 5-May-2023 at 11:30 UT is:
N16E27, ( -416", 316" )

Dear Collaborators,
Solar activity remains high with M-level activity emanating from two
separate regions in the northeast quadrant; NOAA 13293, which retains
its beta-delta configuration and NOAA 13296, which has an anti-Hale
beta configuration and produced an M3.9 flare at 08:05 UT today. Both
regions are continuing to develop and are likely to remain flare
productive. NOAA 13293 shall remain the target region with a Major
Flare Watch in effect, but also include NOAA 13296 in your field of
view if possible.
The position of NOAA 13293 on 4-May-2023 at 11:30 UT is:
N13E28, ( -436", 269" )

Dear Collaborators,
Solar activity is at a low level. Target region NOAA 13282 continues
to be the largest spot group on the visible disk and showed maturing
intermediate spots in the period. Although NOAA 13282 still classed
as a beta/E-type spot group at the start of the UT day this region
now has a beta-gamma magnetic configuration. The largest magnitude
flare since the last message was a C3.6 on 20-Apr-2023 at 09:17 UT
from NOAA 13281. However, the target remains with NOAA 13282 due to
its recent increase in magnetic complexity. Further C-class activity
is expected over the following 24-hour period.
The position of NOAA 13282 on 20-Apr-2023 at 15:00 UT is:
N12W24 , ( 385", 276" )

Dear Collaborators,
The level of solar activity is low. The target area at the North East
limb has been flare-quiet since the last message. NOAA region 13282
continues to be the largest spot group on the visible disk and showed
minor growth in terms of spot area in the period. Although NOAA 13282
decreased in magnetic complexity in its classification that was issued
at the start of the UT day - now being a beta/E-type spot group - this
region may have redeveloped mixed interior polarities (i.e., returning
to a beta-gamma). This region has produced several low C-class flares
since the last message and becomes the new target. C-class flares are
expected in the next 24 hours.
The position of NOAA 13282 on 19-Apr-2023 at 20:00 UT is:
N11W14 , ( 229", 266" )

Dear Collaborators,
Solar activity is at a low level. NOAA 13282 remained as the largest
spot group on the visible disk, but decayed in terms of sunspot area
since the last message. This region retained its classification as a
beta-gamma/E-type spot group and was the source of several low C-class
flares in the period. The target region remains beyond the North East
limb, but produced a footpoint-occulted C1.6 flare on 17-Apr-2023 at
21:43 UT. This limb location remains the target for a further 24 hours.
More C-class activity is expected over the following 24-hour period,
with a small chance for an M-class flare.
The approximate position of this region on 18-Apr-2023 at 15:00 UT is:
N24E90 , ( -872", 387" )

Dear Collaborators,
The level of solar activity is low. Target region NOAA 13282
continues to be the largest sunspot group on the visible disk,
growing slightly in terms of spot area since the last message.
This region is classified as a beta-gamma/E-type sunspot group
and was the source of 2 low C-class flares in the period, while
the largest flare in the period (a footpoint-occulted C9.1 on
16-Apr-2023 at 17:31 UT, so it would most likely have been an
unocculted M-class flare) was produced by a region currently
located beyond the North East limb. This limb location becomes
the new target. More C-class flares are probable in the next
24 hours, with a small chance for a low M-class flare.
The approximate position of this region on 17-Apr-2023 at 18:00 UT is:
N24E90 , ( -873", 387" )

Dear Collaborators,
Target region NOAA 3282 developed somewhat
in its leading polarity portion. 3282 is maintaining
an E-type sunspot group with minor mixed polarities
within its intermediate area. 3282 was the source
of a few minor C-class events since the last message.
NOAA regions 3281 and 3280 also produced minor
C-class events during the past 24 hours.
The position of NOAA 3282 on April 16 at 14:30 UT is:
N12E28 (-441", 278")

Dear Collaborators,
Target region NOAA 3282 has decayed somewhat
in the past 24 hours. The magnetic delta configuration
located within the leading polarity sunspot has
decayed away. The region still has some minor
mixed polarities within the intermediate portion
of its E-type sunspot group. NOAA 3282 was
the source of numerous C-class events and an
isolated M-class event (M1.5 at 04/15/23:27 UT)
since the last message. C-class events expected
with an isolated M-class possible in the next
24 hour period.
The position of NOAA 3282 on April 15 at 15:30 UT is:
N11E43 (-642", 249")

Dear Collaborators,
Target region NOAA 3279 (S20E42) was quiescent
in the past 24 hour period. The target will switch
to NOAA 3282. 3282 is a rapidly developing EFR
located in the northeast. The EFR is currently
displaying a D-type/beta-gamma sunspot group
with a magnetic delta configuration located in
its leading portion. 3282 was the source of 5 C-class
events and an M1.1 event at 04/14/16:18 UT today.
C-class events expected with another M-class
event possible in the next 24 hour period.
The position of NOAA 3282 on April 14 at 14:30 UT is:
N11E57 (-789", 233")

Dear Collaborators,
Target region NOAA 3272 (S23W10) is mostly unchanged
maintaining numerous small sunspots with a weak
beta-gamma magnetic configuration. 3272 produced
one event since the last message (C8.5 at 04/13/10:43 UT).
NOAA region 3279 was the source of 14 C-class events
since the last message. The largest was a C6.7 at
04/13/10:56 UT. 3279 has an E-type sunspot group
with minor polarity mixing. The target will switch from 3272
to 3279 today. If possible, include NOAA 3281 (S23E75)
within your F-O-V. C-class events likely with a slight chance
of an isolated M-class event in the next 24 hours.
The position of NOAA 3279 on April 13 at 14:30 UT is:
S20E55 (-739", -275")
