Dear RHESSI Collaborators,
Solar activity is at a low level. NOAA region 12488 has grown in
spot area and number of spots in the past 24 hours and maintained
a beta/D-type sunspot group. 12488 was the source of the largest
flare since the last message, a C1.4 on 24-Jan-2016 at 04:07 UT.
More low-to-mid C-class flares are possible over the following 24
hours.
The position of NOAA 12488 on 24-Jan-2016 at 14:00 UT is:
N03E04, ( -72", 142" )

Dear RHESSI Collaborators,
The level of solar activity is very low. NOAA region 12487 has decayed
over the previous 24 hours, losing area, number of spots and penumbral
coverage. NOAA 12488 has remained stable and produced the largest event
since the last message (a B7.1 flare on 22-Jan-2016 at 23:47 UT). More
B-class flares are expected over the next 24 hours.
The position of NOAA 12488 on 23-Jan-2016 at 21:30 UT is:
N04E15, ( -254", 155" )

Dear RHESSI Collaborators,
Solar activity remains at a low level. NOAA region 12487 has grown
marginally in spot area and number of spots over the past 24 hours
and remains classified as a beta/D-type sunspot group. This region
has lost some of its penumbral coverage and has produced no flares
since the last message. More C-class activity is possible over the
next 24 hours.
The position of NOAA 12487 on 22-Jan-2016 at 17:00 UT is:
S13E13, ( -209", -135" )

Dear RHESSI Collaborators,
The level of solar activity is low. NOAA region 12487 has continued
to grow in spot area and number of spots over the past 24 hours and
has been classified as a beta/D-type sunspot group. This region has
flared the most since the last message, producing two C-class events
that included the largest magnitude flare (a C2.9 on 21-Jan-2016 at
01:17 UT). Further C-class activity is expected over the following
24 hours as NOAA 12487 continues to show signs of flux emergence.
The position of NOAA 12487 on 21-Jan-2016 at 17:00 UT is:
S13E27, ( -427", -143" )

Dear RHESSI Collaborators,
Solar activity is at a low level. NOAA region 12486 has remained stable
over the previous 24 hours and the spotted region to its North has been
designated as NOAA 12487. This region has a beta/C-type sunspot group
classification and was the source of the joint-largest flare since the
last message (a C1.3 on 20-Jan-2016 at 14:25 UT, with NOAA 12484 being
the source of a C1.3 on 20-Jan-2016 at 07:30 UT). More C-class activity
is probable over the next 24 hours as 12487 continues to show signs of
flux emergence and spot growth.
The position of NOAA 12487 on 20-Jan-2016 at 17:00 UT is:
S13E40, ( -608", -155" )

Dear RHESSI Collaborators,
The level of solar activity remains extremely low. NOAA 12480 has now
rotated over the North West limb. NOAA 12486 has remained stable over
the past 24 hours, but a small set of bipolar spots has developed to
the North of 12486. Quiet-Sun conditions are expected to continue in
the next 24 hours.
The position of NOAA 12486 on 19-Jan-2016 at 11:30 UT is:
S20E47, ( -669", -279" )

Dear RHESSI Collaborators,
Solar activity continues at a very low level. NOAA region 12480 has now
rotated up to the North West limb and will remain the target region until
its high-lying loops have rotated out of view. None of the other regions
on the solar disk have shown any notable signs of spot growth or activity.
Quiet-Sun conditions are expected to continue over the next 24 hours.
The position of NOAA 12480 on 18-Jan-2016 at 17:30 UT is:
N03W89, ( 973", 53" )

Dear RHESSI Collaborators,
Quiet-Sun conditions resume as NOAA 12480 nears the western limb. The
region has been quiescent and unchanged since the last message. It
shall remain the target region for a further 24 hours although no
significant increase in activity is expected.
The position of NOAA 12480 on 17-Jan-2016 at 15:35 UT is:
N03W75, ( 941", 71" )

Dear RHESSI Collaborators,
The target region NOAA 12480 has continued to produce B- and low
C-class flares since the last message. The region is now classified as
an alpha spot and continues to decay to decay as it approaches the
western limb. Further low-level activity possible over the next 24
hours.
The position of NOAA 12480 on 16-Jan-2016 at 15:35 UT is:
N04W61, ( 852", 106" )

Dear RHESSI Collaborators,
There has been a resurgence of activity from the target region NOAA
12480. The region has produced some low C-class flares since the last
message, including a C2.0 flare around 02:00 UT today. The region
continues to decay as it approaches the western limb but may produce
additional isolated low-level events over the next 24 hours.
The position of NOAA 12480 on 15-Jan-2016 at 18:30 UT is:
N03W50, ( 748", 100" )
