Dear RHESSI Collaborators,
Target region NOAA 11511 has maintained spot area coverage and number
of spots, remaining a beta/C-type sunspot group classification. This
region seems to have finished emerging and is likely to decay in the
next few days. B-class activity is expected in the next 24 hours.
The position of NOAA 11511 on 24-Jun-2012 at 14:00 UT is:
N15W37, ( 546", 217" )

Dear RHESSI Collaborators,
Yesterday's target region is now designated as NOAA 11511. This region
remains fairly small with few spots and is classified as a beta/C-type
sunspot group. C-class activity is possible in the following 24 hours.
The position of NOAA 11511 on 23-Jun-2012 at 11:30 UT is:
N15W23, ( 362", 215" )

Dear RHESSI Collaborators,
Yesterday's target region NOAA 11504 has now rotated to the South West
limb,
while a region has emerged near the central meridian over the last 18
hours.
This region has spots but no penumbrae within the leading negative-polarity
field, while the trailing portion contains only pores. C-class activity may
be possible in the next 24 hours if the region continues to emerge.
The approximate position of this region on 22-Jun-2012 at 09:30 UT is:
N15W08, ( 125", 215" )

Dear RHESSI Collaborators,
NOAA region 11504 has maintained its number of spots, but again
decreased in spot area coverage as it rotates towards the South
West limb. This region has decreased in complexity with being
reclassified as a beta/D-type sunspot group, but this is partly
due to its proximity to the limb. C-class activity is probable
before 11504 rotates completely over the limb.
The position of NOAA 11504 on 21-Jun-2012 at 09:00 UT is:
S16W82, ( 899", -264" )

Dear RHESSI Collaborators,
Yesterday's target region NOAA 11504 continues to lose spot area coverage
and number of spots as it rotates towards the solar South West limb. This
region has maintained a beta/E-type sunspot group classification, and has
produced a couple of C-class events in the past 24 hours. Further C-class
activity is probable before NOAA 11504 rotates over the limb, with a very
small chance for an isolated low M-class event.
The position of NOAA 11504 on 20-Jun-2012 at 09:30 UT is:
S16W70, ( 855", -269" )

Dear RHESSI Collaborators,
NOAA region 11504 continues in decay phase, losing area coverage and
number of spots in the last 24 hours. Some of these changes might be
due to NOAA 11504 rotating towards the solar limb, but the Southern
trailing spot has significant fragmentation of its penumbra. Despite
this, 11504 has retained a beta/E-type sunspot group classification.
C-class activity is expected in the following 24 hours, with a small
chance for an isolated M-class event.
The position of NOAA 11504 on 19-Jun-2012 at 09:00 UT is:
S17W57, ( 758", -290" )

Dear RHESSI Collaborators,
Target region NOAA 11504 appears to be in decay phase with losing
a number of spots, while its reclassification to the less complex
beta/E-type sunspot group designation may be partly related to its
rotation towards the solar limb. This region has produced several
C-class events since yesterday's message, with the largest being a
C3.9 flare on 17-Jun-2012 at 17:36 UT. Further C-class activity is
expected in the next 24 hours, with a small chance for an isolated
M-class event.
The position of NOAA 11504 on 18-Jun-2012 at 10:30 UT is:
S17W45, ( 637", -293" )

Dear RHESSI Collaborators,
NOAA region 11504 has grown further in area coverage in the past 24
hours, maintaining a beta-gamma/E-type sunspot group classification.
This region has been the source of several C-class events. Continued
C-class activity is likely in the next 24 hours, while the potential
still remains for an M-class event.
The position of NOAA 11504 on 17-Jun-2012 at 11:00 UT is:
S17W33, ( 494", -295" )

Dear RHESSI Collaborators,
Target region NOAA 11504 has continued to evolve in the past 24 hours,
growing
in area coverage and decreasing in number of spots. This region has
apparently
decreased in complexity with being reclassified as a beta-gamma/E-type
sunspot
group, although it does still contain strong horizontal field gradients.
11504
has produced several C-class events since yesterday's email, the largest
being
a C3.4 flare on 15-Jun-2012 at 13:07 UT. Further C-class activity is
expected,
with a good chance for an M-class event if 11504 continues to grow in area.
The position of NOAA 11504 on 16-Jun-2012 at 09:00 UT is:
S16W17, ( 265", -280" )

Dear RHESSI Collaborators,
In the past 24 hours NOAA region 11504 has maintained spot area and
decreased in number of spots, primarily due to merging of existing
spots. This region remains classified as a beta-gamma-delta/E-type
sunspot group, producing several C-class events and a long-duration
M1.9 flare on 14-June-2012 at 12:52 UT. C-class activity is likely
in the following 24 hours, with a good chance for a low-to-moderate
magnitude M-class event.
The position of NOAA 11504 on 15-Jun-2012 at 09:00 UT is:
S16W04, ( 63", -279" )
