MM#009 Default HESSI Target
by Max Millennium Chief Observer 31 Oct '14

31 Oct '14

Dear RHESSI Collaborators, Solar activity is at a moderate to low level. The largest event, a limb-occulted C8.2 flare was released by NOAA 12192 on 31-Oct-2014 at 01:01 UT. The region has now completely rotated over the limb. The new region, mentioned yesterday, has been designated as NOAA 2201 and shows some signs of flux emergence. The region was responsible for low C-class activity. Further low C-class events are expected with the chance for a high C-class flare. The position of NOAA 12201 on 31-Oct-2014 at 20:10 UT is: S05E54, ( -779", -128" ) 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

Dear RHESSI Collaborators, Solar activity is at a moderate to high level. NOAA 12192 was responsible for high C-class activity and three M-class events, the largest a M3.5 flare on 30-Oct-2014 at 01:35 UT. The region has since rotated over the limb, but further partially limb-occulted flares are expected. The most active on-disk region is a new AR located at S15E55 (responsible for a C3 flare at 17:52 UT). Given the lack of substantial activity on disk, NOAA 12192 will remain the target region. The MFW is ended at this time. Further high C-class activity is expected with the chance for another low M-class event. The position of NOAA 12192 on 30-Oct-2014 at 17:30 UT is: S12W91, ( 944", -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.

MM#003 Major Flare Watch
by Max Millennium Chief Observer 28 Oct '14

28 Oct '14

Dear RHESSI Collaborators, Solar activity is at a moderate to high level. Strong shearing flows continue to bisect the main delta-spot in NOAA region 12192, which maintains its beta-gamma-delta/F-type sunspot group designation. The region was responsible for two M-class events, the largest a M6.6 flare on 28-Oct-2014 at 03:32 UT, since the previous message. The current MM#003 Major Flare Watch will continue for at least the next 24-48 hours as NOAA 12192 retains a strong potential for continued flaring above the M5 level. The position of NOAA 12192 on 28-Oct-2014 at 18:10 UT is: S12W69, ( 883", -228" ) 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 remains at a high level. Further flux emergence within NOAA region 12192 is not readily apparent, but shearing motions can be seen within the main delta-spot, which maintains its beta-gamma-delta/F-type sunspot group designation. The region was responsible for two high M-class and another X-class event (a X2.0 flare on 27-Oct-2014 at 14:47 UT), since the previous message. The current MM#003 Major Flare Watch will continue for the next 24-48 hours as NOAA 12192 retains a strong potential for continued flaring above the M5 level. The position of NOAA 12192 on 27-Oct-2014 at 19:00 UT is: S12W56, ( 789", -244" ) 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.

26 Oct '14

Dear RHESSI Collaborators, Solar activity remains at a high level. NOAA region 12192 emerged some new magnetic flux during the past 24 hours and still retains a beta-gamma-delta/F-type sunspot group designation. This region produced several more high C-class events since yesterday's email as well as an X2.0 flare on 26-Oct-2014 at 10:04 UT. The current MM#003 Major Flare Watch has been in operation now for a week and will continue for the next 24-48 hours because NOAA 12192 retains a strong potential for continued flaring above the M5 level. The position of NOAA 12192 on 26-Oct-2014 at 16:30 UT is: S12W43, ( 647", -260" ) 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.

25 Oct '14

Dear RHESSI Collaborators, The level of solar activity is high. Over the past 24 hours NOAA 12192 initially showed signs of decay before emerging new magnetic flux and strengthening its delta spot. This active region continues to display a beta-gamma-delta/F-type sunspot group classification. 12192 produced several high C-class events since yesterday's message and two X-class events (an X3.1 flare on 24-Oct-2014 at 21:07 UT and an X1.0 flare on 25-Oct-2014 at 16:55 UT that is currently decaying). The MM#003 Major Flare Watch will continue for the next 24-48 hours as NOAA 12192 still retains a strong potential for a further flaring above the M5 level. The position of NOAA 12192 on 25-Oct-2014 at 18:00 UT is: S12W31, ( 487", -271" ) 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.

24 Oct '14

Dear RHESSI Collaborators, Solar activity is at a moderate level. NOAA 12192 is still the largest, most complex and flare-productive active region on the visible disk. This region maintained a beta-gamma-delta/F-type sunspot group classification and grew slightly in sunspot area over the past 24 hours to 2740 uh. NOAA 12192 has decreased in flare frequency somewhat, but still produced 3 C-class events and an M4.0 flare on 24-Oct-2014 at 07:37 UT. The MM#003 Major Flare Watch will remain in effect for another 24 hours as NOAA 12192 retains the potential for a flare above the M5 level. The position of NOAA 12192 on 24-Oct-2014 at 18:30 UT is: S14W16, ( 262", -313" ) 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

23 Oct '14

Dear RHESSI Collaborators, The level of solar activity is moderate-to-high. Activity continues to be dominated by NOAA region 12192 that has grown in sunspot area to 2700 uh - the largest spot area recorded since NOAA 10486 during the Halloween storms of 2003. This active region has maintained a beta-gamma-delta/F-type sunspot group classification and continues to emerge new magnetic flux. NOAA 12192 has produced several C-class flares since the last message and an M1.1 on 23-Oct-2014 at 09:44 UT. The current MM#003 Major Flare Watch will remain in effect for the next 24 hours as NOAA 12192 retains the potential for more flaring above the M5 level. The position of NOAA 12192 on 23-Oct-2014 at 18:30 UT is: S12W04, ( 70", -286" ) 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 a high level. NOAA 12192 dominates the visible disk and has now grown in sunspot area to greater than 2400 uh. This active region has retained a beta-gamma-delta/F-type sunspot group classification even though the primary leading and primary trailing spots have separated in the past 24 hours. Since the last message, NOAA 12192 has produced two M-class flares (an M8.7 on 22-Oct-2014 at 01:16 UT and an M2.7 on 22-Oct-2014 at 05:11 UT) as well as an X1.6 (on 22-Oct-2014 at 14:02 UT). The existing MM#003 Major Flare Watch will remain active for the next 24-48 hours since NOAA 12192 continues to emerge new magnetic flux and retains the potential for further flaring above the M5 level. The position of NOAA 12192 on 22-Oct-2014 at 16:00 UT is: S14E10, ( -166", -318" ) 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, The level of solar activity is moderate. NOAA 12192 remains the most flare-productive region on disk, having grown to a sunspot area greater than 2000 uh and retaining a beta-gamma-delta/F-type sunspot group designation. The primary leading and trailing spots of NOAA 12192 appear to be separating, but this region continues to emerge new flux. NOAA 12192 has produced C-class activity and three M-class events since yesterday's message, the largest being an M1.7 flare on 20-Oct-2014 at 19:53 UT. The MM#003 Major Flare Watch will remain in effect for at least the next 24 hours because NOAA 12192 retains the potential for flaring above the M5 level. The position of NOAA 12192 on 21-Oct-2014 at 22:00 UT is: S13E18, ( -289", -300" ) 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.
