Dear RHESSI Collaborators,
Current target region NOAA 11504 has almost doubled in spot area coverage
in the past 24 hours and continues to evolve into a more complex magnetic
configuration, now classified as a beta-gamma-delta/E-type sunspot group.
This region has produced numerous C-class events since yesterday's email,
and the long-duration M1.2 flare that began on 13-June-2012 at 11:29 UT.
Continued C-class activity is expected in the next 24 hours, with a good
chance for another M-class event if the degree of polarity mixing in NOAA
11504 increases.
The position of NOAA 11504 on 14-Jun-2012 at 09:00 UT is:
S17E09, ( -143", -292" )

Dear RHESSI Collaborators,
NOAA region 11504 continues in growth phase, significantly increasing
in spot area coverage and number of spots. This region has maintained
a beta/E-type sunspot group class, but appears to have developed some
degree of polarity mixing in its intermediate portion since the NOAA
classifications were issued at 00:30 UT. Further C-class activity is
expected in the next 24 hours, with a chance for an M-class event if
new flux emerges within 11504.
The position of NOAA 11504 on 13-Jun-2012 at 09:30 UT is:
S17E23, ( -351", -290" )

Dear RHESSI Collaborators,
Yesterday's target region NOAA 11504 decreased in spot area, but increased
in number of spots and complexity in the past 24 hours. This region is now
classified as a beta/E-type sunspot group and has produced 2 C-class events
since the yesterday's message. Closely neighboring regions 11504 and 11505
both appear to be still in flux emergence phase, developing mature penumbra
around several spots. C-class activity is likely in the next 24 hours, with
a chance for a low M-class event if flux continues to emerge within 11504.
The position of NOAA 11504 on 12-Jun-2012 at 11:00 UT is:
S17E34, ( -506", -287" )

Dear RHESSI Collaborators,
Yesterday's target region NOAA 11504 has increased in both spot area
and number of spots and is classified as a beta/D-type sunspot group.
These increases appear to be to due to new flux emerging within the
region, rather than being due to rotation onto the solar disk. NOAA
11504 has continued to produce C-class events in the past 24 hours.
Further C-class activity is expected, with a good chance for another
M-class event if 11504 continues to experience flux emergence.
The position of NOAA 11504 on 11-Jun-2012 at 09:00 UT is:
S18E46, ( -649", -299" )

Dear RHESSI Collaborators,
Newly numbered region NOAA 11504 has rotated over the South East limb.
This region has a beta/C-type sunspot group classification, but is too
close to the limb to accurately determine its magnetic configuration.
NOAA 11504 has produced three M-class flares in the past 24 hours, the
largest being an M1.9 on 9-June-2012 at 11:20 UT. C-class activity is
expected in the next 24 hours, with a good chance for further M-class
events.
The position of NOAA 11504 on 10-Jun-2012 at 09:30 UT is:
S17E62, ( -798", -280" )

Dear RHESSI Collaborators,
NOAA region 11494 shows signs of decay with decreasing in complexity
over the last 24 hours, despite maintaining spot area and number of
spots. This region is now classified as a beta/C-type sunspot group,
but retains small negative polarity spots in close proximity to the
primary positive spot. C-class activity is probable in the next 24
hours.
The position of NOAA 11494 on 9-Jun-2012 at 11:00 UT is:
S18W39, ( 567", -298" )

Dear RHESSI Collaborators,
Yesterday's target region NOAA 11494 has decreased marginally in both
spot area and number of spots in the past 24 hours, but has increased
in complexity to a beta-gamma/D-type sunspot group class. This region
has continued to produce flares with the largest being a C7.7 event on
8-Jun-2012 at 02:51 UT. Further C-class activity is likely in the next
24 hours, with a small chance for a low M-class event if the degree of
polarity mixing increases.
The position of NOAA 11494 on 8-Jun-2012 at 14:30 UT is:
S18W27, ( 408", -297" )

Dear RHESSI Collaborators,
Yesterday's target NOAA 11493 has decreased in spot area while maintaining
number of spots and a beta-gamma/E-type sunspot group classification.
Today's
target will switch to NOAA 11494, a beta/C-type sunspot group with opposite
polarity spots in close proximity to the primary positive spot. This region
has produced several C-class events since the last message and an M2.1
flare
on 6-Jun-2012 at 19:54 UT. Further C-class activity is expected in the next
24 hours, with a small chance for another low M-class event.
The position of NOAA 11494 on 7-Jun-2012 at 11:00 UT is:
S18W12, ( 188", -295" )

Dear RHESSI Collaborators,
Yesterday's target region NOAA 11493 has generally maintained area and
number of spots, but has increased in complexity to a beta-gamma/E-type
sunspot group classification. C-class events are probable in the next
24 hours, with a small chance for a low M-class event if further mixing
develops close to the leading spot.
The position of NOAA 11493 on 6-Jun-2012 at 09:30 UT is:
N12W10, ( 165", 197" )

Dear RHESSI Collaborators,
NOAA region 11496 appears to be in decay, having decreased in spot
area coverage over the last two days. A newly numbered region lies
to the South between NOAA regions 11493 and 11496 and is designated
as 11501. The large trailing positive spot of 11493 will be the new
target given the proximity of the regions and their likelihood for
interaction. C-class events are expected in the next 24 hours.
The position of NOAA 11493 on 5-Jun-2012 at 17:00 UT is:
N13W01, ( 22", 215" )
