Dear RHESSI Collaborators,
The level of solar activity is low. The new region mentioned in the last
message has now rotated over the east limb (now designated NOAA 11801) and
has a alpha magnetic classification. A small bipole is currently emerging
within the decayed eastern portion of NOAA 11803. Yesterday's target (NOAA
11800) has slowed its flux emergence and now exhibits slight evidence for a
beta-gamma configuration. The region was the source of a B4.9 event on
24-Jul-2013 at 01:24 UT. Further B-class activity is expected with a chance
for an isolated C-class event.
The position of NOAA 11800 on 24-Jul-2013 at 17:30 UT is:
S07W13, ( 207", -198" )

Dear RHESSI Collaborators,
The level of solar activity is low. The largest flare since yesterday's
message
was a B4.6 flare on 22-Jul-2013 at 10:33 UT released by a new region
currently
over the east limb. Considering the current STEREO B EUV image, the region
does not appear to be large. Yesterday's target, NOAA region 11800 has not
produced further significant activity since the previous message. However,
the
region has emerged new flux in its northern portion, in the form of a new
bipole.
Although, the new flux has not resulted in NOAA 11800 gaining a mixed
polarity
classification as of yet. B-class activity is expected with a chance for an
isolated
C-class event.
The position of NOAA 11800 on 23-Jul-2013 at 18:30 UT is:

Dear RHESSI Collaborators,
The level of solar activity is low. The largest flare since yesterday's
message
was a B8.3 flare on 21-Jul-2013 at 12:19 released by NOAA region 11793
(which
now shows no significant signs of a gamma configuration). Yesterday's
target,
NOAA region 11800 has not produced further significant activity since
yesterday's C3.1 flare. The main spots in NOAA 11800 have further separated
but the region is now classified as a beta/D-type region. B-class activity
is
expected with a chance for an isolated C-class event.
The position of NOAA 11800 on 22-Jul-2013 at 18:30 UT is:

Dear RHESSI Collaborators,
The level of solar activity is low. NOAA region 11793 shows signs of
decay with many of the small surrounding spots losing their penumbrae.
This region has maintained overall spot area and increased in number
of spots, while remaining classified by NOAA as a beta-gamma/E-type
sunspot group. NOAA region 11800 has emerged new magnetic flux over
the past 24 hours, being classified by NOAA as a beta/C-type sunspot
group. This new flux has already formed a more substantial leading
polarity spot, with the trailing polarity spot also growing. This
region produced the largest flare since yesterday's message - a C3.1
flare on 21-Jul-2013 at 08:24 UT. More C-class activity is expected
over the following 24 hours, with a small chance for an isolated low
M-class event if 11800 continues to emerge more magnetic flux.
The position of NOAA 11800 on 21-Jul-2013 at 11:00 UT is:
S09E31, ( -481", -217" )

Dear RHESSI Collaborators,
Solar activity remains at a low level. Most of the NOAA regions have
decayed slightly or remained stable. NOAA 11793 continues to be the
largest and most complex region on disk, being classified by NOAA as
a beta-gamma/E-type sunspot group. This region shows some opposite
polarity pores around both the primary leading and primary trailing
spots and was the source of a C2.1 flare on 20-Jul-2013 at 03:34 UT.
Additional C-class events are possible in the next 24 hours, with a
small chance for an isolated low M-class event.
The position of NOAA 11793 on 20-Jul-2013 at 11:00 UT is:
N21E06, ( -93", 264" )

Dear RHESSI Collaborators,
The level of solar activity is low. NOAA region 11791 has continued
to decay over the past 24 hours, decreasing in spot area, number of
spots and being reclassified as a beta/C-type sunspot group. A new
region, designated as NOAA 11800, has rotated over the South East
limb and has been associated with two C2.3 flares on 18-Jul-2013 at
17:56 UT and 19:57 UT. However, the UV flare ribbons of the second
of these flares seem to be located within the currently unspotted
region located further East than NOAA 11800. NOAA 11793 remains the
largest region on disk and has retained a beta-gamma/E-type sunspot
group classification. This region has increased in spot number over
the past 24 hours, and a small positive polarity spot has emerged
over the past 6 hours to the North of the leading negative polarity
spot. Further B-class activity is expected in the following 24-hour
period, with a good chance for C-class events.
The position of NOAA 11793 on 19-Jul-2013 at 11:00 UT is:
N20E18, ( -275", 253" )

Dear RHESSI Collaborators,
Solar activity is at a very low level, with only B-class events over
the past 24 hours. NOAA 11791 has decayed since yesterday's message,
losing its delta spot but regaining a mixed polarity classification
as a beta-gamma/D-type sunspot group. NOAA 11793 continues to be the
largest region on the disk, and is classified as a beta-gamma/E-type
sunspot group. B-class activity is expected over the next 24 hours,
with a chance for C-class events.
The position of NOAA 11793 on 18-Jul-2013 at 10:30 UT is:

Dear RHESSI Collaborators,
The level of solar activity is low. NOAA 11793 has continued to grow
in spot area and number of spots as it rotates further onto the disk,
and is classified by NOAA as a beta-gamma/E-type sunspot group. NOAA
11791 has maintained spot area and number of spots but has decreased
slightly in complexity to a beta-delta/D-type sunspot group. 11791
was the most active of the spotted regions on disk, producing a C1.9
flare on 16-Jul-2013 at 10:10 UT. Further C-class activity is likely
over the next 24 hours, with a very small chance for an isolated low
M-class event.
The position of NOAA 11791 on 17-Jul-2013 at 11:00 UT is:

Dear RHESSI Collaborators,
Solar activity is at a low level. NOAA 11793 has grown in spot area
and number of spots, and has been confirmed as a beta-gamma/E-type
sunspot group classification by NOAA after rotating further on disk.
NOAA region 11791 has maintained spot area and number of spots, with
yesterday's rapid delta spot emergence confirmed by NOAA through its
beta-gamma-delta/D-type sunspot group classification. NOAA 11791 was
the source of 3 C-class events since yesterday's message, the largest
being a C3.6 on 15-Jul-2013 at 10:28 UT. Further C-class activity is
expected over the following 24 hour period, with a chance for a low
M-class event.
The position of NOAA 11791 on 16-Jul-2013 at 09:30 UT is:

Dear RHESSI Collaborators,
Solar activity is at a low level. The region that rotated over the North
East limb is now designated as NOAA 11793. This region is a large dipolar
region with some early indications of polarity mixing between the primary
leading and trailing spots (i.e., beta-gamma magnetic complexity). NOAA
11791 has emerged a positive-polarity spot on the Northern edge of the
maturing negative-polarity trailing spots. These spots appear to share a
common penumbra, which would alter the classification of NOAA 11791 to a
beta-delta/D-type or beta-gamma-delta/D-type sunspot group. This region
produced two C-class flares since yesterday's message, the largest being
a C3.0 on 15-Jul-2013 at 03:11 UT. Further C-class activity is expected
over the next 24 hours, with a chance for an isolated low M-class event
if NOAA 11791 emerges more magnetic flux.
The position of NOAA 11791 on 15-Jul-2013 at 10:30 UT is:
S15E11, ( -178", -313" )
