MM#009 Default HESSI Target
Dear RHESSI Collaborators,
Solar flare activity is very low. The only event in the past
24 hours was a weak B1.5 event at 06/22/00:49 UT
produced by NOAA 2664. 2664 is maintaining both the tiny
B-type/beta sunspot group located in its northern portion
and its reversed polarity H-type/alpha sunspot located
in its southern portion. B-class events are possible in the
next 24 hour period.
The position of NOAA 2664 on June 22 at 12:45 UT is:
N17E55 (Solar X = -742", Solar Y = 259")

MM#009 Default HESSI Target
Dear RHESSI Collaborators,
The east limb target is now numbered NOAA 2664
and classified by NOAA as a C-type/beta sunspot
group. The northern portion of the region has decayed
somewhat. The southern portion remains unchanged
with a round stable mature sunspot. B-class activity is
possible with an isolated C-class event currently less
likely in the next 24 hour period.
The position of NOAA 2664 on June 21 at 14:30 UT is:
N17E68 (Solar X = -839", Solar Y = 266")

MM#009 Default HESSI Target
Dear RHESSI Collaborators,
Target region NOAA 2663 has continued to decay
significantly. 2663 produced a weak B1.4 event at
06/20/05:40 UT. The largest event in the past 24 hours
was a limb occulted B5.0 at 06/19/16:04 UT. Its
source was the region located on the northeastern
limb. The limb region is too close to the limb to ascertain
the magnetic configuration of its sunspot group. It is
possible that there are two separate "stacked" regions.
B-class events possible with a slight chance of an isolated
C-class event in the next 24 hour period.
The approximate position of the target on June 20 at 14:30 UT is:
N17E85 (Solar X = -900", Solar Y = 274")

MM#009 Default HESSI Target
Dear RHESSI Collaborators,
NOAA 2663 is now decaying rapidly. 2663 was the source of
a couple of minor B-class events since the last message.
Minor B-class activity is possible in the next 24 hour period.
A new region located just beyond the northeastern limb at
approximately N17 produced a limb occulted B3.0 event
at 06/19/04:29 UT. This new region will likely become the
target tomorrow after it completes east limb passage.
The position of NOAA 2663 on June 19 at 13:30 UT is:
N12W49 (Solar X = 698", Solar Y = 180")

Dear RHESSI Collaborators,
The target region NOAA 12663 produced a few low B-class events
over the past 24 hours, the largest one of the period being a B2.9
at 13:33 UT on June 18. 12663 remains its beta/D-type configuration
and continues showing flux emergence mainly in its leading portion.
Further B-class activities are expected in the next 24 hours.
The position of NOAA 12663 on June 19 at 01:30 UT is:
N12W42 (619", 178")

Dear RHESSI Collaborators,
Solar activity remains at very low levels. The largest event since
the last message was a B1.4 at 02:51 UT on June 17 produced
by the target region NOAA 12663. 12663 retains its beta/D-type
sunspot group. It shows some flux emergence in its leading portion.
B-level events are likely over the following 24 hours.
The position of NOAA 12663 on June 18 at 01:30 UT is:
N12W29 (449", 177")

Dear RHESSI Collaborators,
Solar activity has been at extremely low levels since the last message.
The target region NOAA 12663 was flare quiet in the past 24 hours. It
is now downgraded to a beta/D-type region, increasing in sunspot area.
12663 is more complex in magnetic configuration than the other sunspot
region (NOAA 12662, N12E27) on the visible disk. B-class activities are
possible in the next 24 hours.
The position of NOAA 12663 on June 17 at 01:30 UT is:
N13W15 (239", 193")

Dear RHESSI Collaborators,
Solar activity has increased slightly since the last message.
Numerous low B-class events were produced by a new emerged
region, now designated as NOAA 12663. 12663 will be today's
target. It grows rapidly and is classified as a beta-gamma/D-type
region. Further B-class activities are expected with a chance of
low C-level events.
The position of NOAA 12663 on June 15 at 23:30 UT is:
N14W00 (0", 220")

Dear RHESSI Collaborators,
Solar activity is at a very low level. The largest event since the
last message was a B3.8 (limb flare) at 18:45 UT on June 13,
produced by yesterday's plage target NOAA 12661. Today the
target will switch to a new sunspot region NOAA 12662 with an
alpha/H-type configuration. Low level activities are possible in
the following 24 hours.
The position of NOAA 12662 on June 14 at 15:30 UT is:
N12E61 (-809", 189")

Dear RHESSI Collaborators,
Solar activity continues to be extremely low with the GOES soft X-ray
flux flat at the ~A8 level. The plage region (previous NOAA 12661) is
almost rotating beyond the west limb. It will be the target for a further
24 hours. Only minor activities are expected in the next 24 hour period.
The position of NOAA 12661 on June 13 at 15:30 UT is:
N07W91 (936", 115")
