Dear RHESSI Collaborators,
Solar activity continues at low levels. NOAA 12303 (N18W85) was the
source of numerous low C-class events before rotating off the visible
disk. Yesterday's target region NOAA 12305 is mostly unchanged
preserving an E-type/beta-gamma configuration. It continues to show
some flux emergence in its leading portion. There is still a chance for
C-class activity over the next 24-48 hours.
The position of NOAA 12305 on March 29 at 11:35 UT is:
S08W26 (Solar X = 418", Solar Y = -33")

Dear RHESSI Collaborators,
Solar activity remains at low levels. NOAA 12309 (N14W86) was the
source of a few C1 events as it was rotating over the west limb.
Yesterday’s target region NOAA 12305 has produced two C2 events
today. 12305 maintains its beta-gamma configuration with increasing
in spot area and count somewhat. 12305 is showing some mixed
polarities in its intermediate portion. It has the potential to produce
further low C-class activity.
The position of NOAA 12305 on March 28 at 12:35 UT is:
S09W17 (Solar X = 278", Solar Y = -42")

Dear RHESSI Collaborators,
Solar activity has returned to low levels. There were three C1 events
produced by the target region 12305 in the past 24 hours. 12305 has
lost some of its spot area, number of spots, and magnetic complexity.
It is classified as a C-type/beta-gamma configuration. Even though it
is now in decay phase, 12305 will continue to be the target region.
Additional low C-class events are likely within the next 24 hours.
The position of NOAA 12305 on March 27 at 12:35 UT is:
S08W02 (Solar X = 33", Solar Y = -20")

Dear RHESSI Collaborators,
Solar activity is at intermediate-to-low levels. The target region NOAA
12305 has produced a few low C-level events since the last message.
12305 continued to increase its sunspot area and number of spots, and
was classified as an E-type/beta-gamma-delta magnetic configuration.
It is showing some flux emergence at both the leading and trailing portions.
Further C-class activity is expected over the next 24 hours.
The position of NOAA 12305 on March 26 at 12:35 UT is:
S08E12 (Solar X = -198", Solar Y = -22")

Dear RHESSI Collaborators,
Solar activity has increased over the past 24 hours. Target region,
NOAA 12305, was the source of three C-class events (the largest being
a C8.7 at 04:36 on March 25). 12305 increased its spot area, and was
once classified as a beta-gamma-delta magnetic type, though the delta
configuration has somewhat decayed now. 12305 continues to show
some mixed polarities in its intermediate portion. C-class activity is
expected with a slight chance for an M-class event in the next 24 hour
period.
The position of NOAA 12305 on March 25 at 12:35 UT is:
S08E25 (Solar X = -404", Solar Y = -29")

Dear RHESSI Collaborators,
Solar activity remains at low levels with numerous B-class events
emanating from the visible disk. The target region NOAA 12305 continues
to show signs of growth over the past 24 hours, increasing in spot area
and number of spots. 12305 maintains its E-type/beta-gamma configuration
and bright H-alpha plage. It is showing some flux emergence in the
intermediate portion. C-class events are still possible in the next 24
hours.
The position of NOAA 12305 on March 24 at 12:35 UT is:
S08E37 (Solar X = -575", Solar Y = -41")

Dear RHESSI Collaborators,
The solar activity continues at a low level. The largest event since
the last message was a C3.6 at 08:49 UT on March 23 produced by an
undesignated region (S25E86) over the South East limb. Yesterday's
target region NOAA 12305 has increased in spot area and count, and
now is classified as an E-type/beta-gamma magnetic configuration.
C-class activity is possible in the next 24 hours.
The position of NOAA 12305 on March 23 at 12:35 UT is:
S08E51 (Solar X = -742", Solar Y = -60")

Dear RHESSI Collaborators,
Solar activity is at a low level. Yesterday’s target, NOAA region
12303, has remained flare quiet since the last message. NOAA 12305
has shown signs of growth over the previous 24 hours, increasing
in spot area and number of spots. This region was first classified
today as a beta/D-type sunspot group, but now appears to show mixed
polarities in its intermediate portion (making 12305 a beta-gamma
region classification). C-class activity is possible over the next
24 hours.
The position of NOAA 12305 on 22-Mar-2015 at 22:00 UT is:
S08E55, ( -781", -66" )

Dear RHESSI Collaborators,
The level of solar activity is low. The high-lying loops of NOAA
12297 have completely rotated out of view. The target will switch
to NOAA 12303, the largest region on the visible disk. NOAA 12303
is an alpha/H-type sunspot group, but produced the largest event
in the past 24 hours - a C1.7 flare on 21-Mar-2015 at 07:35 UT.
More C-class flares are possible over the following 24 hours.
The position of NOAA 12303 on 21-Mar-2015 at 23:30 UT is:
N19E12, ( -193”, 421” )

Dear RHESSI Collaborators,
Solar activity is at a low level. The spots of NOAA 12297 have now
rotated over the South West limb, but this region was classified as
a beta-gamma/C-type sunspot group before completing limb transit.
NOAA 12297 was the source of the largest event in the past 24 hours
- a C7.9 flare on 20-Mar-2015 at 00:57 UT. More C-class activity is
possible over the next 24 hours before the high-lying loops of NOAA
12297 rotate completely out of view.
The position of NOAA 12297 on 20-Mar-2015 at 22:00 UT is:
S17W90, ( 921”, -280” )
