Dear RHESSI Collaborators,
The largest event since the last message was a B3.7 at 20:01 UT
on May 25 produced by NOAA 12711 (N06W57). The target region
NOAA 12712 was the source of three low B-class events. 12712
remains its C-type/beta magnetic classification but increasing in
number of spots. It continues to show flux emergence in its trailing
portion. Further B-class activities are expected with a chance of an
isolated low C-class flare in the next 24 hours.
The position of the target region on May 26 at 03:10 UT is:
N14E54 (-745", 242")

Dear RHESSI Collaborators,
The largest event since the last message was a B9.8 at 5/24/12:22 UT
produced by NOAA 12710 (N17E23). Our target region, now designated
as NOAA 12712, was the source of 5 low B-class flares. 12712 has a
beta/C-type classification. It shows some dynamic surges in H-alpha
images as well as flux emergence. Additional B-class activities are
expected with a chance of C-class events over the following 24 hours.
The position of the target region on May 25 at 03:10 UT is:
N13E73 (-883", 220")

Dear RHESSI Collaborators,
The largest event since the last message was a C2.0 at 18:03 UT
on May 23 produced by the target limb region (unnumbered yet)
which was also the source of numerous B-class events. This target
region is rotating onto the visible disk. Two another regions with
sunspots (NOAA 12710 and 12711) were also producing some very
minor events, in particular, the rapidly emerged region 12711 produced
a low B-class flare. Further B-class activities are expected with a chance
of C-class events in the next 24 hours.
The approximate position of the target region on May 24 at 03:10 UT is:
N14E78 (-850", 240")

Dear RHESSI Collaborators,
Solar activity has increased in the past 24 hours. Two B-class
flares (a B2.8 at 5/22/04:29 UT and a B8.9 at 5/22/14:47 UT)
and also several A-class events were produced by a region
beyond the east limb. Today we will watch this limb region with
some overlying loops visible. If possible, please also include
yesterday's target region (now designated as NOAA 12710,
N16E54) in your field of view. Further B-class events are expected
with a chance of C-class activities in the next 24 hours.
The approximate position of the target region on May 22 at 16:10 UT is:
N12E89 (-900", 210")

Dear RHESSI Collaborators,
Solar activity continues at a background level and the visible solar disk
remains spotless. Yesterday's target region rotates onto the solar disk
but is unnumbered yet. Quiet-Sun conditions should continue over the
next 24 hour period.
The approximate position of the target region on May 21 at 10:10 UT is:
N17E80 (-850", 300")

Dear RHESSI Collaborators,
Solar activity continues at background levels with NOAA 12709 now
beyond the western limb. A new spotless, compact active region has
rotated onto the eastern limb, and is currently unnumbered and
unclassified. This shall be the new target region with a slight chance
of an isolated low-level event over the next 24 hours.
The approximate position of the target region on 20-May-2018 at 22:00 UT is:
N20E88, ( -890", 325" )

Dear RHESSI Collaborators,
Quiet-Sun conditions continue. NOAA 12709 remains spotless and
quiescent, and is now on the eastern limb. It shall remain the target
region for a further 24 hours although no change in activity is
expected.
The position of NOAA 12709 on 19-May-2018 at 15:30 UT is:
N04W86, ( 943", 68" )

Dear RHESSI Collaborators,
Solar activity remains unchanged. The target region, NOAA 12709,
remains quiescent as it approaches the western limb. No activity
expected from the decaying plage region over the next 24 hours.
The position of NOAA 12709 on 18-May-2018 at 22:00 UT is:
N04W77, ( 922", 74" )

Dear RHESSI Collaborators,
Solar activity continues at very low levels. NOAA 12709 produced two
low A-class flares since the last message. Its decaying plage shall
remain the target region for a further 24 hours although no
significant increase in activity is expected at this time.
The position of NOAA 12709 on 17-May-2018 at 16:10 UT is:
N04W57, ( 795", 87" )

Dear RHESSI Collaborators,
Solar X-ray flux continues at background levels. NOAA 12709 remains
spotless but is still bright in H-alpha and X-ray emission. It shall
continue to be the target region for a further 24 hours although no
change in activity is expected at this time.
The position of NOAA 12709 on 16-May-2018 at 16:10 UT is:
N04W42, ( 635", 97" )
