Dear RHESSI Collaborators,
Solar activity continues at the C1 level with minor events from NOAA
12178, 12181, 12182, and a plage region in the northeast quadrant over
the past 24 hours. NOAA 12178 remains largely unchanged but shall
continue to be the target region. Further low-level events possible.
The position of NOAA 12178 on 6-Oct-2014 at 11:35 UT is:
S01W44, ( 668", -94" )

Dear RHESSI Collaborators,
Quiet-Sun conditions have returned with X-ray flux remaining
predominantly below the B-level since the last message. NOAA 12178 has
shown signs of decay in its trailing portion but shall remain the
target region. Only minor activity expected over the next 24 hours.
The position of NOAA 12178 on 5-Oct-2014 at 15:35 UT is:
S01W32, ( 510", -109" )

Dear RHESSI Collaborators,
Solar activity is low. Yesterday's target (NOAA 12178)
was responsible for C-class activity. No significant
changes are seen in the region. Further C-class events
are probable with a chance for a high C-class flare.
The position of NOAA on 4-Oct-2014 at 15:35 UT is:
S01W17, ( 281", -121" )

Dear RHESSI Collaborators,
The level of solar activity is low. Since the previous
message, yesterday's target (NOAA 12178) released
the largest event, a C9 flare on 3-Oct-2014 at 07:30
UT (the event source was determined from GOES/SXI).
NOAA 12178 maintains the largest area and most
complex configuration (a weak gamma) of the ARs on
disk. Further C-class activity is probably with the chance
for a low M-class event.
The position of NOAA 12178 on 3-Oct-2014 at 19:00 UT is:
S02W05, ( 84", -143" )

Dear RHESSI Collaborators,
The level of solar activity is moderate. Since the previous
message, yesterday's target, NOAA 12172, has released
a M1 flare on 2-Oct-2014 at 17:30 UT. Given that NOAA
12172 is at the West limb, the target will switch to NOAA
12178, which shows the largest spot area and the most
X-ray activity of the regions still on disk. Low C-class
activity is expected with the chance for a moderate
C-class event.
The position of NOAA 12178 on 2-Oct-2014 at 19:00 UT is:
S02E08, ( -141", -143" )
The position of NOAA on at UT is:

Dear RHESSI Collaborators,
The level of solar activity is low. Since the previous
message, NOAA 12172 has released a C6.7 flare on
1-Oct-2014 at 03:06 UT. Given that NOAA 12177 has
largely decayed and has not produced significant
activity, the target will switch to NOAA 12172. Further
C-class activity is expected with the chance for a low
M-class event.
The position of NOAA 12172 on 1-Oct-2014 at 19:00 UT is:
S10W68, ( 873", -208" )

Dear RHESSI Collaborators,
The level of solar activity is low. Since the previous
message, NOAA 12173 was responsible for low
C-class activity but shows signs of further decay.
NOAA 12177 has ceased emerging significant new
flux but maintains a weak mixed polarity spot in its
intermediate portion. Low C-class events are possible
with a chance for a high C-class flare.
The position of NOAA 12177 on 30-Sep-2014 18:15 UT is:
N11E21, ( -337", 79" )

Dear RHESSI Collaborators,
The level of solar activity is moderate. Since the previous
message, NOAA 12173 was responsible for C-class activity
and the largest event, a M1.0 flare on 28-Sep-2014 at 17:33
UT. However, the region continues to decay. NOAA 12175
maintains its strong delta configuration, but its flux emergence
appears to have subsided and no significant activity was
released. On the other hand, NOAA 12177 has emerged new
flux in its following and intermediate portion, resulting in a
mixed polarity spot. The region has was responsible for
moderate C-class activity, so far. Further C-class events are
likely with a chance for an M-class flare.
The position of NOAA 12177 on 29-Sep-2014 18:30 UT is:
N12E33, ( -509",105" )

Dear RHESSI Collaborators,
The level of solar activity is moderate. Since the previous message,
NOAA 12173 was responsible for an M5.1 flare on 28-Sep-2014 at
2:58 UT. However, the region does not show a strong polarity separation
line or further substantial flux emergence. On the other hand, NOAA
12175 is rapid emerging flux in the following portion, and its delta spot
has strengthened. High C-class activity is expected, with a chance for
an M-class event.
The position of NOAA 12175 on 28-Sep-2014 16:40 UT is:
N15W45, ( 655",168" )

Dear RHESSI Collaborators,
The level of solar activity is low to moderate. Since the
previous message, yesterday's target (NOAA 12172)
released several high C-class events, including a C8.7
flare on 26-Sep-2014 at 05:43 UT. New flux emergence
is evident to the SW of its leading portion. The region
does not show a strong polarity separation line, but exhibits
a gamma configuration. On the other hand, NOAA 12172
(responsible for moderate C-class activity, so far) has
emerged rapidly since the previous message and exhibits
a strong shearing delta configuration, evidenced by the
rapidly moving positive sunspot. High C-class activity
is expected, with a chance for an M-class event.
The position of NOAA 12175 on 26-Sep-2014 19:15 UT is:
N15W23, ( 356", 144" )
