MM#009 Default HESSI Target
Dear RHESSI Collaborators,
NOAA 2390 has completed west limb passage. We will switch
to a region that NOAA reports is located beyond the
southeastern limb. The new target region was the source of
a limb occulted long-duration B7.9 event at 08/02/22:43 UT.
This event was associated with a CME. B-class activity
probable with a chance of an isolated C-class event in the
next 24 hour period.
The approximate position of the target on Aug. 03 at 11:00 UT is:
S09E89 (Solar X = -934", Solar Y = -149")

MM#009 Default HESSI Target
Dear RHESSI Collaborators,
Solar flare activity was at low levels during the past 24 hours.
The current background x-ray flux is at the B2.6 level.
The largest event since the last message was a C1.5 at
08/01/20:05 UT produced by target region NOAA 2390.
2390 was also the source of 5 B-class events. 2390 will
continue to be the target region until it completes west limb
passage. No significant flare activity expected in the next
24 hour period.
The position of NOAA 2390 on August 02 at 14:35 UT is:
S14W88 (Solar X = 916", Solar Y = -230")

MM#009 Default HESSI Target
Dear RHESSI Collaborators,
Solar flare activity continues at a very low level. The
background x-ray flux is currently flat at the B2.5 level.
The largest event in the past 24 hours was a B8.0 at
08/01/01:31 UT. The source region was NOAA 2393
(N17E25). Target region NOAA 2390 is slowly decaying
but is maintaining its D-type sunspot group with a weak
beta-gamma magnetic configuration. No significant flare
activity expected in the next 24 hour period.
The position of NOAA 2390 on August 01 at 14:35 UT is:
S15W75 (Solar X = 882", Solar Y = -267")

MM#009 Default HESSI Target
Dear RHESSI Collaborators,
Solar flare activity continues at a very low level. The
current background x-ray flux is at the B2.2 level.
The largest event was a B5.9 produced by target region
NOAA 2390. No significant flare activity expected anytime
soon.
The position of NOAA 2390 on July 31 at 11:35 UT is:
S15W60 (Solar X = 791", Solar Y = -289")

Dear RHESSI Collaborators,
Solar flare activity remains at very low levels. The target region NOAA
12390 has been flare quiet over the past 24 hours. It continues to decay
and has been downgraded to a beta region. No significant flare activity
is expected in the next 24 hours.
The position of NOAA 12390 on July 30 at 11:35 UT is:
S15W46 (Solar X = 658", Solar Y = -306")

Dear RHESSI Collaborators,
Solar activity continues at a very low level with GOES X-ray flux flat
at ~B2 level. The target region NOAA 12390 has begun to decay and
fragment but maintains its beta-gamma/D-type configuration. B-class
activity is possible in the next 24 hours.
The position of NOAA 12390 on July 29 at 11:35 UT is:
S15W33 (Solar X = 498", Solar Y = -318")

Dear RHESSI Collaborators,
Solar activity has been at very low levels for the past 24 hours. The
target region NOAA 12390 was the source of a B5.5 flare since the
last message. 12390 increases in spot area and number of spots. It
is showing magnetic flux cancellation in its intermediate portion. B-class
activity is expected with a chance of C-class activity in the next 24 hours.
The position of NOAA 12390 on July 28 at 11:35 UT is:
S17W20 (Solar X = 310", Solar Y = -357")

Dear RHESSI Collaborators,
Solar activity is at a very low level. Yesterday's target region NOAA
12389 has decayed over the past 24 hours, decreasing slightly in spot
area and number of spots. It has been flare quiet since the C1.1 event.
Another active region, NOAA 12390, has grown in spot area and magnetic
complexity, with a beta-gamma/D-type configuration now. 12390 was the
source a few B-class events since the last message. It will be today's
target region. B-class activities are expected in the next 24 hour period,
with a good chance for some C-class events.
The position of NOAA 12390 on July 27 at 14:35 UT is:
S15W08 (Solar X = 127", Solar Y = -329")

Dear RHESSI Collaborators,
Solar activity remains at a low level. NOAA 12389 has grown slightly
in spot area and number of spots over the past 24 hours, and is now
classified as a beta-gamma/D-type sunspot group. This region was the
source of the largest flare since yesterday's message - a C1.1 flare
on 26-Jul-2015 at 12:28 UT. B-class flares are expected in the next
24 hours, with a good chance for more C-class activity.
The position of NOAA 12389 on 26-Jul-2015 at 20:00 UT is:
S11E37, ( -559", -249" )

Dear RHESSI Collaborators,
The level of solar activity is low. Yesterday's target region has now
been designated as NOAA 12389 and classified as a beta/C-type sunspot
group. This region continued to be the most flare productive region on
disk, being the source of two C-class flares since yesterday's message
(including the largest event of the period - a C2.6 on 24-Jul-2015 at
17:49 UT). B-class flares are expected over the next 24 hours, with a
good chance for more C-class activity.
The position of NOAA 12389 on 25-Jul-2015 at 20:00 UT is:
S11E51, ( -722", -234" )
