MM#009 Default HESSI Target
by Max Millennium Chief Observer 30 Apr '15

30 Apr '15

Dear RHESSI Collaborators, Solar activity continues at very low levels. The largest X-ray event since the last message was a C1.0 at 16:20 UT yesterday from the limb region NOAA 12327 (S08W90). The visible solar disk is basically spotless. We continue to watch the unnumbered region, but close to its left filament. The right filament has been oscillating and may disappear. No significant activity is expected. The position of the target on April 30 at 11:35 UT is: S23E21 (Solar X = -300”, Solar Y = -320”) See http://www.SolarMonitor.org for images and http://solar.physics.montana.edu/max_millennium/ops/observing.shtml for a description of the current Max Millennium Observing Plan.

Dear RHESSI Collaborators, Solar activity is at very low levels with GOES X-ray flux flat at B3 level. Yesterday's target region NOAA 12331 is rotating over the west limb, so is NOAA 12327. Another active region NOAA 12333 is visible on the solar disk, but shows a simple alpha configuration. There is an unnumbered small region in the southeast quadrant, which seems to connect two large filaments. Today we switch the target to this unnumbered region. There is a chance of filament eruption in the next few days. The position of target region on April 29 at 11:35 UT is: S19E32 (Solar X = -500”, Solar Y = -280”) See http://www.SolarMonitor.org for images and http://solar.physics.montana.edu/max_millennium/ops/observing.shtml for a description of the current Max Millennium Observing Plan.

Dear RHESSI Collaborators, Solar activity continues at very low levels. The largest event since the last message was a C1.9 at 05:13 UT today produced by the target region NOAA 12331. The large filament at the northeast limb was erupted at ~14:00 UT today, which was associated with a two-ribbon flare and a CME. NOAA 12331 has been downgraded to a beta region. It will be the primary target for one more day, with low-level activity possible in the next 24 hours. NOAA 12333 (N20W09) shows some signs of growth, with a chance of low-level activity. The position of NOAA 12331 on April 28 at 15:35 UT is: S09W82 (Solar X = 932", Solar Y = -138") See http://www.SolarMonitor.org for images and http://solar.physics.montana.edu/max_millennium/ops/observing.shtml for a description of the current Max Millennium Observing Plan.

Dear RHESSI Collaborators, Solar activity is at very low levels. The largest X-ray event since the last message was a C1.4 at 20:51 UT yesterday produced by NOAA 12327. There is a large filament currently visible near the northeast limb. The target region NOAA 12331 produced a small filament eruption at 21:42 UT yesterday, which was associated with a small CME toward the south- west direction. 12331 retains its D-type/beta-gamma configuration with increasing in spot area. It continues to be today's target region. If possible, also include 12327 (S08W58) within your field of view. Very low-level activity is expected over the next 24 hours. The position of NOAA 12331 on April 27 at 15:35 UT is: S10W68 (Solar X = 871", Solar Y = -137") See http://www.SolarMonitor.org for images and http://solar.physics.montana.edu/max_millennium/ops/observing.shtml for a description of the current Max Millennium Observing Plan.

Dear RHESSI Collaborators, Solar activity continues at low levels. The largest event since the last message was a C1.9 at 18:03 UT yesterday from the northwest limb. The target region NOAA 12331 was the source of two C1 events today. 12331 maintains its D-type/beta-gamma magnetic configuration. It shows some flux emergence in its trailing portion. Low-level activity is likely in the next 24 hours. The position of NOAA 12331 on April 26 at 11:35 UT is: S09W54 (Solar X = 763", Solar Y = -103") See http://www.SolarMonitor.org for images and http://solar.physics.montana.edu/max_millennium/ops/observing.shtml for a description of the current Max Millennium Observing Plan.

Dear RHESSI Collaborators, Solar activity is at low levels. The target region NOAA 12331 was the source of three C1 events since the last message. 12331 has developed a D-type/beta-gamma magnetic classification. Low-level activity is expected over the next 24 hour period. The position of NOAA 12331 on April 25 at 15:35 UT is: S10W42 (Solar X = 630", Solar Y = -107") See http://www.SolarMonitor.org for images and http://solar.physics.montana.edu/max_millennium/ops/observing.shtml for a description of the current Max Millennium Observing Plan.

Dear RHESSI Collaborators, Solar activity has been at low levels, with numerous C1 events emanating from the solar disk since the last message. Yesterday's target region NOAA 12326 has rotated over the west limb. NOAA 12331 has a complex D-type/beta magnetic configuration, showing some flux emergence in both the leading and trailing portions. It will be today's target region. Low activity is possible in the next 24 hours. The position of NOAA 12331 on April 24 at 11:35 UT is: S09W26 (Solar X = 414", Solar Y = -77") See http://www.SolarMonitor.org for images and http://solar.physics.montana.edu/max_millennium/ops/observing.shtml for a description of the current Max Millennium Observing Plan.

Dear RHESSI Collaborators, Solar activity has been at low-to-intermediate levels since the last message. The largest event was a long duration M1.1 event at 09:18 UT today from the northwest limb (N07W80). NOAA 12326 was the source of a few low C-class events as well as a C7.3 at 11:58 UT today. 12326 has developed rapidly over the past 24 hours. It will be today's target region. Further low-level activity is likely in the next 24 hours. The position of NOAA 12326 on April 23 at 11:35 UT is: N15W76 (Solar X = 894", Solar Y = 265") See http://www.SolarMonitor.org for images and http://solar.physics.montana.edu/max_millennium/ops/observing.shtml for a description of the current Max Millennium Observing Plan.

Dear RHESSI Collaborators, Solar activity has been at moderate-to-low levels over the past 24 hours. The target region NOAA 12322 was the source of 5 low M- class and several C-class events since the last message, the largest one being an M4.0 at 15:24 UT yesterday. 12322 will be the target region for one more day, with a chance of further occulted activity. NOAA 12324 (N19W42) also has the potential to produce low-level activity, with some positive flux emerging from its negative leading spot. The position of NOAA 12322 on April 22 at 15:35 UT is: N11W91 (Solar X = 936", Solar Y = 179") See http://www.SolarMonitor.org for images and http://solar.physics.montana.edu/max_millennium/ops/observing.shtml for a description of the current Max Millennium Observing Plan.

Dear RHESSI Collaborators, Solar activity has increased significantly in the last a few hours. Three low M-class events emanated from the solar disk, an M2.2 at 10:17 UT from the northeast limb (N16E80), and two occulted events (an M1.0 at 07:08 UT and an M2.2 at 11:49 UT) from NOAA 12322. NOAA 12322 has developed rapidly over the last 24 hours, though with a C-type/beta configuration and small spot area and count. Because of its activity history, we switch the target region to 12322 today. Additional occulted activity is likely in the next 24 hours. The position of NOAA 12322 on April 21 at 11:35 UT is: N11W78 (Solar X = 917", Solar Y = 198") See http://www.SolarMonitor.org for images and http://solar.physics.montana.edu/max_millennium/ops/observing.shtml for a description of the current Max Millennium Observing Plan.
