MM#009 Default HESSI Target
by Max Millennium Chief Observer 21 May '15

21 May '15

MM#009 Default HESSI Target Dear RHESSI Collaborators, Solar flare activity continues to be very low. The current background x-ray flux is at the B2.2 level. Target region, NOAA 2351 has decayed significantly. The new target is an EFR located in the northeastern quadrant. No noteworthy solar flare activity is expected in the next 24 hours. The position of the target on May 21 at 14:45 UT is: N06E30 (Solar X = -473", Solar Y = 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 flare activity is at very low levels. The background x-ray flux is currently at the B2.7 level. The target region, now numbered NOAA 2351, was the source of two minor C-class events since the last message. No significant flare activity expected anytime soon. The position of NOAA 2351 on May 20 at 11:35 UT is: N22E42 (Solar X = -589", Solar Y = 379") 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 2339 has completed west limb passage. The new target is an unnumbered region located in the northeastern quadrant. The region was the source of the largest event since the last message (C2.3 at 05/19/11:59 UT). The region has a cluster of tiny spots with minor mixed polarities. Another C-class event is possible in the next 24 hour period. The position of the target on May 19 at 12:00 UT is: N22E55 (Solar X = -722", Solar Y 375") 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. The background x-ray flux is currently at the B4 level. The largest event since the last message was a C1.1 produced by NOAA 2339 at 05/18/08:21 UT. No significant flare activity is expected during the next 24 hours. The position of NOAA 2339 on May 18 at 11:35 UT is: N12W87 (Solar X = 926", 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.

MM#009 Default HESSI Target Dear RHESSI Collaborators, Solar flare activity is at a very low level. The background x-ray flux is currently flat at the B5 level. NOAA 2339 is mostly unchanged and is now rotating over the west limb. A C-class event is possible in the next 24 hours. An isolated M-class event is unlikely. The position of NOAA 2339 on May 17 at 11:35 UT is: N11W79 (Solar X = 914", Solar Y = 188") 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, NOAA 2339 is mostly unchanged and continues to produce minor C-class events. The largest was a C2.5 event at 05/15/23:29 UT. Additional C-class activity is expected again in the next 24 hours with only a slight chance of an isolated M-class event. The position of NOAA 2339 on May 16 at 11:35 UT is: N12W66 (Solar X = 849", Solar Y = 214") 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 2339, has lost magnetic complexity and is now classified as an F-type/beta region but it is displaying penumbral growth within its trailing polarity portion. 2339 was the source of several C-class events since the last message. The largest was a C4.8 at 05/14/17:53 UT. Additional C-class events probable with only a slight chance of an isolated M-class event in the next 24 hour period. The position of NOAA 2339 on May 15 at 15:35 UT is: N11W54 (Solar X = 755", Solar Y = 206") 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 most interesting solar activity since the last message was a filament eruption/two-ribbon flare with an associated C9.2 x-ray event at 05/13/18:18 UT. The filament was located just east of the trailing portion of NOAA 2339 at approximately N15W18. Target region 2339 continues to slowly decay but is maintaining its F-type/beta-gamma classification. C-class activity is probable with only a slight chance of an isolated M-class event in the next 24 hour period. The position of NOAA 2339 on May 14 at 11:35 UT is: N13W41 (Solar X = 608", Solar Y = 247") 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 2339 continues in decay phase but is maintaining an F-type sunspot group with a beta-gamma magnetic configuration. 2339 was the source of numerous low-level C-class events in the past 24 hours. The largest was a C3.2 at 05/13/11:11 UT. 2339 will produce C-class events along with the possibility of an isolated M-class event in the next 24 hour period. NOAA 2342, N18E13, has new flux emergence with mixed polarities and could become the next target region if development continues. The position of NOAA 2339 on May 13 at 15:35 UT is: N14W28 (Solar X = 434", Solar Y = 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.

MM#009 Default HESSI Target Dear RHESSI Collaborators, Target region NOAA 2339 has decayed somewhat especially within the trailing portion but is still a large F-type/beta-gamma region. 2339 was the source of C-class activity in the past 24 hours. C-class events expected with the chance of an isolated M-class event in the next 24 hours. The position of NOAA 2339 on May 12 at 11:30 UT is: N13W12 (Solar X = 193", 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.
