Dear RHESSI Collaborators,
Solar activity continues at low levels. The largest event since the
last message was a C1.1 flare at 00:10 UT from NOAA 12288, which is
now beyond the western limb. The target region NOAA 12290 continues to
develop in size but retains its beta/D-type configuration. Further
B-level flares expected with chance for some low C-level activity.
The position of NOAA 12290 on 23-Feb-2015 at 10:04 UT is:
N20E12, ( -190", 440" )

Dear RHESSI Collaborators,
Solar activity is at a very low level. NOAA region 12287 produced no
activity in the past 24 hours while maintaining spot area and number
of spots. This region has been reclassified as a beta/D-type sunspot
group. NOAA 12209 has grown marginally in spot area over the previous
24 hours and is also classified as a beta/D-type sunspot group. The
largest magnitude flare of the past 24 hours (a B7.1 on 21-Feb-2015
at 18:20 UT) was produced from a location slightly westward of this
region. Further B-class activity is expected over the next 24 hours.
The position of NOAA 12290 on 22-Feb-2015 at 16:30 UT is:
N19E22, ( -345”, 420” )

Dear RHESSI Collaborators,
The level of solar activity is low. NOAA region 12286 produced more
C-class activity in the past 24 hours as it rotated over the South
West limb. NOAA 12287 has decreased marginally in both spot area and
number of spots, being reclassified as a beta/C-type sunspot group.
B-class flares are expected over the next 24 hours.
The position of NOAA 12287 on 21-Feb-2015 at 14:00 UT is:
N14W12, ( 192”, 347” )

Dear RHESSI Collaborators,
Solar activity remains at a low level. NOAA region 12286 displayed
the greatest flare activity in the past 24 hours, producing C-class
events (a C1.1 on 19-Feb-2015 at 17:42 UT and a C1.5 on 20-Feb-2015
at 10:01 UT). However, this region has now rotated up to the South
West limb. Yesterday’s target, NOAA 12287, has maintained spot area
and increased marginally in number of spots, remaining classified
as a beta/D-type sunspot group. This region also displayed activity
since yesterday’s message, producing a B6.1 flare on 20-Feb-2015 at
01:06 UT. Further B-class flares are expected over the next 24 hour
period, with a reasonable chance for further low C-class activity.
The position of NOAA 12287 on 20-Feb-2015 at 13:00 UT is:
N14E01, ( -14”, 349” )

Dear RHESSI Collaborators,
The level of solar activity is low. NOAA 12282 has again decreased
marginally in spot area and number of spots as it rotates further
towards the North West limb. This region remains classified as a
beta/C-type sunspot group and produced the largest magnitude event
in the previous 24 hours (a C3.5 flare on 18-Feb-2015 at 21:53 UT).
Yesterday’s target region is now designated as NOAA 12287 and has
formed several more small spots since yesterday’s message. B-class
flares are expected over the next 24 hours, with a chance for more
C-class activity.
The position of NOAA 12287 on 19-Feb-2015 at 14:00 UT is:
N14E13, ( -217”, 346” )

Dear RHESSI Collaborators,
Solar activity is at an extremely low level. NOAA 12282 has decreased
marginally in spot area and number of spots over the past 24 hours as
it rotates towards the North West limb, and remains classified as a
beta/C-type sunspot group. A new, currently unnumbered, region is in
emergence in the North East quadrant. This region has already formed
several small spots and was the source of a B5.7 flare on 18-Feb-2015
at 11:00 UT. More B-class flares are expected over the next 24 hours,
with a chance for C-class activity.
The approximate position of this region on 18-Feb-2015 at 14:00 UT is:
N14E28, ( -440”, 335” )

Dear RHESSI Collaborators,
The level of solar activity remains very low. NOAA region 12282 has
maintained spot area and number of spots in the past 24 hour period
and continues to be classed as a beta/C-type sunspot group. B-class
flares are expected over the next 24 hour period, with a chance for
C-class activity.
The position of NOAA 12282 on 17-Feb-2015 at 14:00 UT is:
N11W45, ( 673”, 266” )

Dear RHESSI Collaborators,
Solar activity continues to be at a very low level. NOAA 12282 has
decayed further in the past 24 hour period, decreasing in number of
spots and losing its mixed magnetic classification to be designated
a beta/C-type sunspot group. C-class activity is possible over the
following 24 hour period.
The position of NOAA 12282 on 16-Feb-2015 at 12:30 UT is:
N11W31, ( 491”, 283” )

Dear RHESSI Collaborators,
The level of solar activity is at a very low level. NOAA 12282
remains the largest and most complex region on the visible disk.
This region has maintained spot area over the past 24 hours, but
has continued to show signs of decay by increasing in number of
spots. 12282 has maintained classification as a beta-gamma/C-type
sunspot group, but has only produced a single B-class flare since
yesterday’s message (a B6.2 on 15-Feb-2015 at 09:02 UT). C-class
flares are possible over the next 24 hour period.
The position of NOAA 12282 on 15-Feb-2015 at 18:00 UT is:
N11W19, ( 311”, 293” )

Dear RHESSI Collaborators,
Solar activity continues to be at a very low level. NOAA 12282
has emerged a minor amount of magnetic flux but has also shown
signs of decay in the previous 24 hour period. This region is
now classified as a beta-gamma/C-type sunspot group. C-class
flares are possible over the following 24 hours, with a small
chance for an isolated low M-class flare if NOAA 12282 emerges
more magnetic flux.
The position of NOAA 12282 on 14-Feb-2015 at 16:30 UT is:
N10W05, ( 86”, 281” )
