MM#009 Default HESSI Target Dear RHESSI Collaborators, New flux with minor mixed polarities is emerging within the intermediate portion of target region NOAA 2712. 2712 was the source of several B-class events since the last message. The largest was a B5.0 at 05/31/01:08 UT. B-class activity probable with a C-class event possible in the next 24 hour period. The position of NOAA 2712 on May 31 at 13:30 UT is: N16W17 (Solar X = 266", Solar Y = 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.

MM#009 Default HESSI Target Dear RHESSI Collaborators, The B-type/beta sunspot group in NOAA 2712 is currently in decay phase losing sunspot count and sunspot area. The weak mixed polarities and weak magnetic shear located within the region's intermediate and trailing plage has simplified since the C2.7 event on May 28. B-class activity is still possible with the chance of another C-class event less likely in the next 24 hour period. . The position of NOAA 2712 on May 30 at 16:10 UT is: N16W05 (Solar X = 079", Solar Y = 275") 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, Target region NOAA 2712 displayed significant and rapid emerging flux soon after yesterday's message was issued. 2712 added to its sunspot area and sunspot count especially within its intermediate and trailing portions. 2712 was the source of numerous B-class events and an isolated C2.7 event at 05/28/17:10 UT. B-class events probable with the chance of another isolated C-class event in the next 24 hour period. The position of NOAA 2712 on May 29 at 07:00 UT is: N15E14 (Solar X = -222", 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 Dear RHESSI Collaborators, Solar flare activity continues at a very low level. Target region NOAA 2712 (B-type/beta) has decayed within its leading portion but has developed slightly within its trailing portion. B-class events possible with only a very slight chance of an isolated C-class event in the next 24 hours. The position of NOAA 2712 on May 28 at 07:00 UT is: N15E24 (Solar X = -373", Solar Y = 262") 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 a very low level. No flares (>B1.0) have occurred since the last message. The target region NOAA 12712 only shows some small EUV jets in its middle portion. Only Low-level events are possible in the next 24 hour period. The position of NOAA 12712 on May 27 at 16:10 UT is: N15E33 (-499", 262") 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 very low levels. The largest event since the last message was a B1.1 at 1:00 UT on May 27 produced by the target region NOAA 12712. 12712 is mostly unchanged preserving a beta/C-type classification. It seems to show some mixed polarities in its intermediate portion. Only low-level events are expected in the following 24 hours. The position of NOAA 12712 on May 27 at 03:10 UT is: N15E41 (-601", 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.

Dear RHESSI Collaborators, The largest event since the last message was a B3.7 at 20:01 UT on May 25 produced by NOAA 12711 (N06W57). The target region NOAA 12712 was the source of three low B-class events. 12712 remains its C-type/beta magnetic classification but increasing in number of spots. It continues to show flux emergence in its trailing portion. Further B-class activities are expected with a chance of an isolated low C-class flare in the next 24 hours. The position of the target region on May 26 at 03:10 UT is: N14E54 (-745", 242") 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 largest event since the last message was a B9.8 at 5/24/12:22 UT produced by NOAA 12710 (N17E23). Our target region, now designated as NOAA 12712, was the source of 5 low B-class flares. 12712 has a beta/C-type classification. It shows some dynamic surges in H-alpha images as well as flux emergence. Additional B-class activities are expected with a chance of C-class events over the following 24 hours. The position of the target region on May 25 at 03:10 UT is: N13E73 (-883", 220") 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 largest event since the last message was a C2.0 at 18:03 UT on May 23 produced by the target limb region (unnumbered yet) which was also the source of numerous B-class events. This target region is rotating onto the visible disk. Two another regions with sunspots (NOAA 12710 and 12711) were also producing some very minor events, in particular, the rapidly emerged region 12711 produced a low B-class flare. Further B-class activities are expected with a chance of C-class events in the next 24 hours. The approximate position of the target region on May 24 at 03:10 UT is: N14E78 (-850", 240") 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 in the past 24 hours. Two B-class flares (a B2.8 at 5/22/04:29 UT and a B8.9 at 5/22/14:47 UT) and also several A-class events were produced by a region beyond the east limb. Today we will watch this limb region with some overlying loops visible. If possible, please also include yesterday's target region (now designated as NOAA 12710, N16E54) in your field of view. Further B-class events are expected with a chance of C-class activities in the next 24 hours. The approximate position of the target region on May 22 at 16:10 UT is: N12E89 (-900", 210") 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.
