MM#003 Major Flare Watch
by Max Millennium Chief Observer 25 Feb '11

25 Feb '11

MM#003 Major Flare Watch Dear RHESSI Collaborators, A large leader sunspot is visible on the NE limb. This new region was the likely source of the M3.5 event yesterday at 07:31 UT. This region is located northeast of newly numbered NOAA 1163. If possible, include 1163 within your F-O-V. An event equal to M5 or larger is possible in the next few days. The approximate position of the target on February 25 at 11:00 UT is: N20E85 (Solar X = -908", Solar Y = 339") 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.

MM#003 Major Flare Watch Dear RHESSI Collaborators, At this time we are implementing Max Millennium Coordinated Observing Plan #003 (Region Likely To Produce Major Flares). An active region located just behind the NE limb was the source of an M3.5 event at 02/24/07:31 UT. The region is too close to the east limb to ascertain its magnetic configuration. A major flare (M5 class event or greater) is possible. The position of the target on February 24 at 07:30 UT is: N14E87 (Solar X = -940", Solar Y = 239") 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.

MM#009 Default HESSI Target
by Max Millennium Chief Observer 23 Feb '11

23 Feb '11

MM#009 Default HESSI Target Dear RHESSI Collaborators, Both NOAA regions 1161 and 1162 continue in slow decay phase. 1161 produced a C1.2 event at 02/23/12:23 UT. Another C-class event is possible today. The position of NOAA 1161 on February 23 at 12:30 UT is: N11W63 (Solar X = 849", Solar Y = 237") 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.

MM#009 Default HESSI Target
by Max Millennium Chief Observer 22 Feb '11

22 Feb '11

MM#009 Default HESSI Target Dear RHESSI Collaborators, NOAA 1158, located beyond the west limb, produced another C-class event since the last message. The target will switch to NOAA 1161. 1161 and 1162 are slowly decaying with simple magnetic configurations but an isolated C-class event is still possible. The position of NOAA 1161 on February 22 at 12:30 UT is: N11W49 (Solar X 720", Solar Y = 261") 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.

MM#009 Default HESSI Target

21 Feb '11

MM#009 Default HESSI Target Dear RHESSI Collaborators, Target region, NOAA 1158, produced a few C-class events in the past 24 hours. The largest was a C7.8 at 02/21/10:12 UT. The trailing portion of this large region is on the west limb. We'll watch1158 again today. Further interesting limb events possible. The likely target tomorrow will be NOAA regions 1161/1162. 1161/1162 have been the source of low-level C-class activity. The position of NOAA 1158 on February 21 at 12:30 UT is: S21W91 (Solar X = 905", Solar Y = -346") 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.

MM#009 Default HESSI Target

MM#009 Default HESSI Target Dear RHESSI Collaborators, No M-class events since the last message but NOAA region 1158 and dual regions 1161/1162 have the potential to produce an isolated M-class event. Target region 1158 is now rotating over the west limb. C-class activity possible with the chance of an isolated M-class event in the next 24 hours. The position of NOAA 1158 on February 20 at 12:30 UT is: S19W85 (Solar X = 914", Solar Y = -303") 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.

MM#003 Major Flare Watch Dear RHESSI Collaborators, Based on newly found data, it seems that the major M6.6 event at 02/18/10:11 UT had Major Flare Watch region NOAA 1158 as its source region not NOAA 1162 as it was reported yesterday. The M6.6 location is confirmed by the full-disk SDO/EVE Soft X-ray image obtained at the time of the flare. The target will switch back to NOAA 1158. Another event equal to or greater than M5 is possible before west limb passage. NOAA 1162 produced numerous C-class events and a few lower-level M-class yesterday and remains capable to produce C-class events with a slight chance of another M-class event. The position of NOAA 1158 on February 19 at 12:30 UT is: S19W71 (Solar X = 868", Solar Y = -277") 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.

MM#003 Major Flare Watch

MM#003 Major Flare Watch Dear RHESSI Collaborators, A strong EFR located between NOAA 1160 and 1161 was the source of an M6.6 event at 02/18/10:11 UT. This region has a beta-gamma-delta magnetic configuration and continues in strong growth phase. NOAA 1158 continues to slowly decay. It produced numerous C-class events yesterday. We'll continue a Major Flare Watch but switch from 1158 to the new EFR in the NE. Another M5 or stronger event is possible from the new region. Another M-class event is also possible from 1158. The position of the target EFR on February 18 at 8:30 UT is: N18E04 (Solar X = -064", Solar Y = 411") 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.

MM#003 Major Flare Watch Dear RHESSI Collaborators, NOAA 1158 has lost some of its magnetic complexity since the last message. It was the source of numerous C-class events. Even though it is now in decay phase, it could still produce another mid to high level M-class event in the next few days. The position of NOAA 1158 on February 17 at 12:30 UT is: S21W46 (Solar X = 653", Solar Y = -270") 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.
