Dear RHESSI Collaborators,
Solar activity remains at very low levels with the GOES soft X-ray
flux at B1 level. There was only a small filament eruption at the
edge of the target region NOAA 12411 at around 09/06/04:30 UT.
NOAA 12411 seems to have a beta magnetic configuration now.
We will watch 12411 for one more day. Only a slight chance for
low C-class activity.
The position of NOAA 12411 on September 6 at 11:35 UT is:
N13E43 (Solar X = (-634", Solar Y = 127")

Dear RHESSI Collaborators,
The GOES soft X-ray flux continues at a B-class level. There were
a few low B-class events emanating from several active regions.
A small filament eruption occurred at ~09/04/18:30 UT around
NOAA 12410, which was associated with a two-ribbon flare and
a weak CME. Yesterday's target region has now designated as
NOAA 12411, with classified as an Alpha/H-type magnetic
configuration (seems too close to the east limb to exactly ascertain
its configuration). NOAA 12411 appears to be the most active
region on the solar disk. B-class activities are expected with a slight
chance of some low C-class activity in the next 24 hour period.
The position of NOAA 12411 on September 5 at 11:35 UT is:
N14E57 (Solar X = (-775", Solar Y = 165")

Dear RHESSI Collaborators,
Solar activity continues at very low levels. The largest event
since the last message was a B4.4 at 09/04/05:13 UT produced
by NOAA 12409 (N03E19). There was a CME at ~09/03/18:00 UT
(seems beyond the southwestern limb). Yesterday's target region
NOAA 12407 has been flare quiet and rotated over the limb. Today
the target will be an unnumbered region, N14E72. This region is
rotating onto the visible disk, and too close to the east limb to
obtain its magnetic configuration. No significant activity is expected
in the next 24 hours.
The position of the target on September 4 at 12:30 UT is:
N14E72 (Solar X = -890", Solar Y = 210")

Dear RHESSI Collaborators,
Solar activity remains at low levels. The largest event in the past 24
hours was a C1.7 limb flare at 09/03/11:28 UT produced by the target
region NOAA 12407. There occurred a CME at ~09/02/14:30 UT (its
source region seems beyond the northwestern limb, and has nothing
to do with the C1.7 flare). We will watch NOAA 12407 for one more
day before it completely rotates over the west limb. Additional occulted
C-class activity might be possible.
The position of NOAA 12407 on September 3 at 12:30 UT is:
N17W91 (Solar X = 909", Solar Y = 277")

Dear RHESSI Collaborators,
Solar activity continues at low levels. The largest event since the last
message was a B5.0 at 09/02/07:50 UT produced by the target region
NOAA 12407. 12407 increased its spot area slightly but remains a
beta/C-type sunspot group. It has only a slight chance of producing a
low level C-class activity before rotating off the west limb.
The position of NOAA 12407 on September 2 at 11:35 UT is:
N16W82 (Solar X = 905", Solar Y = 244")

Dear RHESSI Collaborators,
Solar activity is at a very low level now. The GOES soft X-ray flux
has been at B-class level since the last message. NOAA 12403
has completely rotated over the west limb. Today the target will be
NOAA 12407, which has a beta/C-type sunspot group. There is a
filament oscillating around NOAA 12407. Low level C-class activity
might be possible in the next 24 hours.
The position of NOAA 12407 on September 1 at 11:35 UT is:
N15W69 (Solar X = 858", Solar Y = 203")

Dear RHESSI Collaborators,
Solar activity has returned to a low level as NOAA 12403 rotates
over the southwestern limb. 12403 produced a C2.2 event at
08/31/04:55 UT, which was associated with a weak CME. Occulted
C-class activity is likely in the next 24 hours.
The position of NOAA 12403 on August 31 at 14:35 UT is:
S15W91 (Solar X = 917", Solar Y = -241")

MM#009 Default HESSI Target
Dear RHESSI Collaborators,
NOAA 2403 is now located mostly beyond the southwestern
limb. 2403 produced a couple of C-class events and a very
long-duration M1.4 event at 08/30/03:30 UT. No significant
x-ray events expected in the next 24 hour period.
The position of NOAA 2403 on August 30 at 12:30 UT is:
S15W89 (Solar X =917", Solar Y = -417")

MM#009 Default HESSI Target
Dear RHESSI Collaborators,
NOAA 2403 is mostly unchanged maintaining its F-type
beta-gamma-delta sunspot group. The magnetic delta
configuration is located within the large leader sunspot.
2403 produced numerous C-class events and an isolated
M2.1 event at 08/28/19:03 UT. C-class events expected
with the chance of another M-class event before 2403
completes west limb passage.
The position of NOAA 2403 on August 29 at 14:35 UT is:
S15W78 (Solar X = 897", Solar Y = -267")

MM#009 Default HESSI Target
Dear RHESSI Collaborators,
NOAA 2403 continues to decay especially within its trailing
portion. 2403 is currently classified as an F-type/beta-gamma
sunspot with a weak magnetic delta configuration located in
its leading polarity sunspot. 2403 was the source of numerous
C-class events and an isolated M2.2 event at 08/28/13:16 UT.
C-class events expected with the chance of another M-class
event in the next 24 hour period. A major flare =/>M5 is now
not likely.
The position of NOAA2403 on August 28 at 12:30 UT is:
S15W64 (Solar X = 825", Solar Y = -294")
