Dear RHESSI Collaborators,
The level of solar activity remains low. NOAA regions 12108 and
12109 have shown signs of evolution over the past 24 hours, both
increasing in complexity. These regions are both classified as
beta-gamma-delta/E-type sunspot groups, but 12108 may have lost
its delta spot. NOAA 12109 displays larger spot area and number
of spots and was the source of the largest flare since the last
email (a C4.3 flare on 7-Jul-2014 at 07:58 UT). Further C-class
activity is likely over the next 24 hours.
The position of NOAA 12109 on 7-Jul-2014 at 15:00 UT is:
S08E13, ( -206", -188" )

Dear RHESSI Collaborators,
Solar activity has increased slightly over the past 24 hours. A number
of low C-level events have emanated from NOAA 12108 and NOAA 12109;
both classified as beta-gamma regions. NOAA 12109 shall remain the
target region with further C-level activity possible.
The position of NOAA 12109 on 6-Jul-2014 at 20:00 UT is:
S08E24, ( -381", -183" )

Dear RHESSI Collaborators,
Solar activity continues at low levels despite the presence of several
large active regions on the visible hemisphere. The target region,
NOAA 12109, has continued to increase in size and complexity, and is
now classified as a beta-gamma region. Increased activity over the
next 24 hours still possible.
The position of NOAA 12109 on 5-Jul-2014 at 15:35 UT is:
S08E40, ( -602", -173" )

Dear RHESSI Collaborators,
Solar X-ray flux remains constant near the C1 level with no
significant activity since the last message. NOAA 12104 and NOAA 12107
have both begun to decrease in both size and complexity. The new
target region shall be NOAA 12109, a beta/D-type region in the
southeast quadrant. The region has shown signs of flux emergence along
its trailing edge and polarity mixing in its core. Chance for some
C-level activity over the next 24 hours.
The position of NOAA 12109 on 4-Jul-2014 at 07:35 UT is:
S08E56, ( -776", -160" )

Dear RHESSI Collaborators,
Solar activity continues at low levels with only a few low C-level
events since the last message. NOAA 12104 maintains its
beta-gamma-delta configuration and continues to develop in size,
particularly in its trailing spot. Potential still exists for
increased activity from the target region.
The position of NOAA 12104 on 3-Jul-2014 at 11:00 UT is:
S12E18, ( -286", -244" )

Dear RHESSI Collaborators,
Solar activity is currently at low levels after a flurry of activity
from NOAA 12106, including an M1.4 at 11:05 UT yesterday. The target
region NOAA 12104 has remained quiescent despite its continued growth
and beta-gamma-delta configuration. Nearby NOAA 12107 has also been
upgraded to a beta-gamma region. Still a chance of further C-level
events from these two regions, with possibility of a low M-class
flare.
The position of NOAA 12104 on 2-Jul-2014 at 07:35 UT is:
S11E34, ( -519", -220" )

Dear RHESSI Collaborators,
Solar activity continues at intermediate levels, with NOAA 12104 and
12106 both producing C-level events over the past 24 hours. The
largest was a C6.0 flare at ~07:30 UT today. The target region NOAA
12104 continues to show signs of growth, and has now been upgraded to
a beta-gamma-delta region due to negative flux emergence with in the
penumbra of the positive leader spot. Further C-level activity
expected with a good chance for a low M-class flare. Also include NOAA
12107 in your field of view if possible.
The position of NOAA 12104 on 1-Jul-2014 at 07:35 UT is:
S11E46, ( -668", -212" )

Dear RHESSI Collaborators,
Solar activity continues at the C-level. NOAA 12104 remains active,
with events also emanating from NOAA 12107 and an occulted region
behind the northeast limb. NOAA 12104 continues to show signs of flux
emergence and polarity mixing in its trailing spot. Additional C-class
flares expected with chance for an isolated low M-class flare. Also
include NOAA 12107 in your field of view if possible.
The position of NOAA 12104 on 30-Jun-2014 at 06:00 UT is:
S10E60, ( -806", -186" )

MM#009 Default HESSI Target
Dear RHESSI Collaborators,
The southeastern limb target region is now numbered
NOAA 2104. 2104 was the source of a few C-class events
since the last message. The largest was a C4.9 at
06/29/11:52 UT. 2104 is currently displaying a
compact D-type/beta-gamma sunspot group. Additional
C-class activity expected with the chance of an isolated
M-class event in the next 24 hour period.
The position of NOAA 2104 on June 29 at 13:00 UT is:
S10E70 (Solar X = -874", Solar Y = -178")

MM#009 Default HESSI Target
Dear RHESSI Collaborators,
The target region (NOAA 2096/2097) has significantly decayed.
The new target is a region located on the southeastern limb.
A large leading sunspot is now visible but it's too close to the
limb to ascertain its magnetic configuration. The southeastern
region and a region located just beyond the northeastern limb
were the source of C-class activity since the last message.
These regions are in the location of old NOAA regions 2080 and
2085 in the south and 2082 in the north. Both east limb regions
have the potential to produce additional C-class activity with a
possible chance of an isolated M-class event in the next 24 hours
The approximate position of the target on June 28 at 07:45 UT is:
S12E89 (Solar X = -923", Solar Y -197")
