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

31 Mar '14

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" ) 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 30 Mar '14

30 Mar '14

Dear RHESSI Collaborators, The current level of solar activity is high. Since the previous message, yesterday's target (NOAA 12017) was responsible for an X1.0 flare on 29-Mar-2014 at 17:48 UT, followed by a moderate M-class flare (during GOES eclipse) on 30-Mar-2014 at 11:55 UT. The region has decayed partially since yesterday, but still shows a mixed polarity spot, just East of the main leading spot. Due to the enhanced probability of a >M5 event, the Major Flare Watch will continue for at least one more day. Further low M-class activity is likely, with a chance for a moderate M-class event. The position of NOAA 12017 on 30-Mar-2014 at 16:20 UT is: N10W43, ( 647", 246" ) 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 29 Mar '14

29 Mar '14

Dear RHESSI Collaborators, The current level of solar activity is moderate. In addition to a series of C-class events, yesterday's target (NOAA 12017) was responsible for the largest events since the previous message, a M2.0 on 28-Mar-2014 at 19:18 UT and a M2.6 on 28-Mar-2014 at 23:51 UT. The region now shows evidence for both further flux emergence and strong shearing within its main delta-spot, within the North-West portion of the AR. Due to the enhanced probability for a M5.0 or greater event, a Major Flare Watch is now in effect. Further C-class activity is expected with a chance for a moderate to high M-class flare. The position of NOAA 12017 on 29-Mar-2014 at 15:00 UT is: N10W28, ( 450", 264" ) 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 28 Mar '14

28 Mar '14

Dear RHESSI Collaborators, The current level of solar activity is low-moderate. Yesterday's target (NOAA 12010) was responsible for the largest event since the previous message, a C4.8 flare on 27-Mar-2014 at 20:29 UT. The region has remained quiescent since, has continued to decay, and is now progressing over the limb. NOAA 2014 is showing some flux emergence within its intermediate portion, but it does not appear to be increasing the complexity of the region, which is a weak gamma. On the other hand, a new bipole has emerged at the Northern edge of the leading spot within NOAA 12017, resulting in the formation of a delta-spot. So far the region has produced low C-class activity. Further C-class activity is expected with a chance for a low M-class flare. The position of NOAA 12017 on 28-Mar-2014 at 15:45 UT is: N10W16, ( 257", 273" ) 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 current level of solar activity is low. The magnetic configuration of NOAA 12014 has decayed and simplified. Since the previous message, yesterday's target (NOAA 12010) has further decayed, but was responsible for low C-class activity. A small bipole has emerged to the North- West of the region, possibly leading to the destabilisation. Further low C-class activity is expected. The position of NOAA 12010 on 27-Mar-2014 at 16:00 UT is: S14W63, ( 831", -181" ) 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 current level of solar activity is low. Since the previous message, yesterday's target (NOAA 12010) has further decayed, but still maintains a gamma magnetic configuration. The region was responsible for C-class activity since the previous message. Further low C-class activity is expected with a chance for a moderate C-class event. The position of NOAA 12010 on 26-Mar-2014 at 17:00 UT is: S14W49, ( 710", -159" ) 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 current level of solar activity is low. Since the previous message, yesterday's target (NOAA 12014) has decayed significantly, while NOAA 12010 was responsible for C-class activity. NOAA 12010 is also in the decay stages, but still shows strong polarity separation line segments of limited extent. Low C-class activity is possible with a chance for a moderate C-class event. The position of NOAA 12010 on 25-Mar-2014 at 15:00 UT is: S14W35, ( 541", -141" ) 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 current level of solar activity is low-moderate. Since the previous message, NOAA 12010 emerged flux within its following portion and released several C-class events. Small mixed polarity spots are visible within the intermediate portion. On the other hand, yesterday's target, NOAA 12014, is also undergoing continued flux emergence within its intermediate portion. 12014 was responsible for the largest event since the previous message, a C4.5 flare on 24-Mar-2014 at 00:10 UT. 12014 exhibits a more highly mixed polarity configuration and also exhibits a mixed polarity spot within its intermediate portion. Further C-class activity is expected, with a chance for a high C-class flare. The position of NOAA 12014 on 22-Mar-2014 at 21:45 UT is: S14E14, ( -232", -123" ) 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 current level of solar activity is low-moderate. Since the previous message, yesterday's target (NOAA 12010) was responsible for low C-class activity. Flux emergence is evident in the North-West portion. However, NOAA 12014 exhibits continual rapid flux emergence in its intermediate portion, resulting in a more complex configuration. The region was responsible for a series of C-class events, including the largest since the previous message, a C5.1 flare on 23-Mar-2014 at 03:48 UT. Further C-class activity is expected with the chance for a high C-class event. The position of NOAA 12014 on 23-Mar-2014 at 17:00 UT is: S14E26, ( -406", -130" ) 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 current level of solar activity is low. Since the previous message, yesterday's target (NOAA 12008) was responsible for low C-class activity. The flux emergence within the region appears to have subsided, but it appears that the two main spots in the following portion may merge to form a delta spot. On the other hand, flux has emerged in the intermediate portion of NOAA 12010, resulting in a strong East-West oriented polarity separation line (PSL), and several small mixed polarity spots. Furthermore, the filament traversing the PSL has undergone brightenings, but has not yet erupted. Further C-class activity is expected with the chance for a high C-class event. The position of NOAA 12010 on 22-Mar-2014 at 21:45 UT is: S15E01, ( -17", -135" ) 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.
