MM#009 Default HESSI Target
Dear RHESSI Collaborators,
The current level of solar flare activity remains very low.
No significant activity expected in the next 24 hours.
NOAA 2026 is decaying but will be the target for today.
There is an active region a few days from east limb passage
located approximately S14 which is near the location of old
NOAA 2010. This region is likely the next target.
The position of NOAA 2026 on April 09 at 13:00 UT is:
S12W51 (Solar X = 729", Solar Y = -136")

MM#009 Default HESSI Target
Dear RHESSI Collaborators,
Solar flare activity continues at a very low level.
NOAA 2026 was the source of only minor C-class events.
2026 has stabilized and is no longer in growth phase.
It is maintaining an E-type sunspot group with a weak
beta-gamma magnetic configuration. No significant
flare activity expected in the next 24 hour period.
The position of NOAA 2026 on April 08 at 17:00 UT is:
S12W41 (Solar X = 616", Solar Y = -123")

MM#009 Default HESSI Target
Dear RHESSI Collaborators,
Solar flare activity is currently at a low level. The largest
event in the past 24 hours was a C4.0 event at 04/07/06:31 UT.
Its source region was NOAA 2026. New flux is emerging
in the leading portion of the region. Another C-class event
is probable in the next 24 hours.
The position of NOAA 2026 on April 07 at 13:00 UT is:
S10W25 (Solar X = 400", Solar Y = -073")

MM#009 Default HESSI Target
Dear RHESSI Collaborators,
Solar flare continues at a very low level. The target region
(NOAA 2021) was the source of very minor C- and B-class
events. NOAA 2030, N11E09, has flux emergence within its
trailing sunspot but it currently doesn't appear to be significant
enough to change from 2021 to it. C- and B-class activity
possible in the next 24 hours.
The position of NOAA 2021 on April 06 at 15:30 UT is:
S13W65 (Solar X = 847", Solar Y = -171")

MM#009 Default HESSI Target
Dear RHESSI Collaborators,
Solar flare activity is currently at a low level. Target region
NOAA 2021 has decayed somewhat in the past 24 hours
but is maintaining a D-type sunspot group with mixed polarities
and bright plage. A C-class event is probable with a slight
chance of an isolated M-class event in the next 24 hours.
The position of NOAA 2021 on April 05 at 13:00 UT is:
S13W52 (Solar X = 738", Solar Y = -151")

Dear RHESSI Collaborators,
The current level of solar activity is low-moderate. Since
the previous message, yesterday's target (NOAA 12030)
was responsible for low C-class activity and its flux
emergence appears to have subsided. The largest event,
a C8.3 flare on 4-Apr-2014 at 13:48 UT, was released by
NOAA 12027, a small beta region that is likely being
destabilised by NOAA 12030 and is not expected to
produce further significant activity. NOAA 12026 shows
strong flux emergence and a small sheared mixed polarity
spot with weak umbrae, but was only responsible for low
C-class activity. On the other hand, NOAA 12021 shows
strong rapid flux emergence and a large mixed polarity spot.
So far, the region has released a C6.2 flare on 4-Apr-2014 at
14:54 UT. Further high C-class activity is expected with a
chance for an M-class event.
The position of NOAA 12021 on 4-Apr-2014 at 15:00 UT is:
S13W40, ( 602", -136" )

Dear RHESSI Collaborators,
The level of solar activity is low. Yesterday's target NOAA region
12027 has shown little evolution since producing the M6.5 flare on
2-Apr-2014 at 13:18 UT. In contrast, the nearby and newly numbered
NOAA 12030 has produced three C-class events, the largest being a
C5.5 on 3-Apr-2014 at 04:04 UT. This region has been classified as
a beta/C-type sunspot group, and has continued to emerge new flux
over the past 24 hours (including the formation of spots with more
mature penumbrae). More C-class activity is expected over the next
24 hours.
The position of NOAA 12030 on 3-Apr-2014 at 17:30 UT is:
N10E47, ( -696", 238" )

Dear RHESSI Collaborators,
The level of solar activity is moderate-to-high. Yesterday's target
NOAA region 12026 continued to increase in number of spots despite
showing no increase in spot area. This region was reclassified as a
beta-gamma/D-type sunspot group and was the source of 4 low C-class
flares in the past 24 hours. NOAA 12027 has also produced 5 C-class
flares as well as the largest flare event since yesterday's message,
an M6.5 flare on 2-Apr-2014 at 13:18 UT. This region is classified
as an alpha/H-type sunspot group, with extended following-polarity
plage. Note that at this time we are *not* initiating a Major Flare
Watch, because of the simplicity of this region's structure. More
C-class activity is expected over the next 24 hours, with a chance
for a low M-class flare.
The position of NOAA 12027 on 2-Apr-2014 at 16:00 UT is:
N13E46, ( -676", 288" )

Dear RHESSI Collaborators,
Solar activity is at a low level. NOAA region 12021 has grown over
the past 24 hours, increasing in spot area and forming leading and
trailing spots with more mature penumbrae. Yesterday's target NOAA
12026 has also grown in spot area as well as number of spots, but
some of that is most likely due to rotation further onto the disk.
This region is classed as a beta/D-type sunspot group and displays
a highly fragmented set of leading polarity spots, with possible
signs of polarity mixing having developed in its intermediate spot
region. Further C-class activity is likely, with a chance for an
isolated low M-class flare.
The position of NOAA 12026 on 1-Apr-2014 at 16:00 UT is:
S11E55, ( -775", -121" )

Dear RHESSI Collaborators,
The current level of solar activity is low-moderate. Since the
previous message, yesterday's target (NOAA 12017) was
responsible for an C7.6 flare on 30-Mar-2014 at 21:15 UT, but
is significantly decayed. NOAA 12014 was responsible for the
largest event since the previous message, a M1.4 flare on
30-Mar-2014 at 08:07 UT, but is now rotating over the limb.
NOAA 12021 is currently emerging flux, but has not produced
significant activity. On the other hand, NOAA 12026 has recently
rotated over the East limb and has released at least 6
low-moderate C-class flares. But due to the region's proximity to
the limb, its magnetic configuration cannot be reliably determined.
The Major Flare Watch is ended at this time. Further moderate
C-class activity is expected with a chance for a high C-class flare.
The position of NOAA 12026 on 31-Mar-2014 at 15:00 UT is:
S11E68, ( -873", -141" )
