MM#009 Default HESSI Target Dear RHESSI Collaborators, Target region NOAA 1778, S17W22, has decayed significantly since the last message. It is now nearly spotless. 1778 did manage to produce a C1.5 event at 06/30/09:18 UT. Recently emerged NOAA 1781 slowly developed a D-type/beta-gamma sunspot group yesterday and will become today's default target. 1781 was the source of a minor C1.1 event at 06/29/16:09 UT. Another C-class event is possible in the next 24 hours. The position of NOAA 1781 on June 30 at 13:00 UT is: N22W26 (Solar X = 384", Solar Y = 315") 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 1778 developed a negative polarity sunspot just north and slightly east of the original positive polarity leader. The region has decayed somewhat in its trailing area. 1778 remains classified as an E-type/beta region. 1778 was the source of a C1.6 event at 06/28/17:05 UT. The brightest region on the visible disk is recently emerged NOAA 1781 located at N22W12. It is currently classified as a D-type/beta region. The target will continue to be NOAA 1778. A C-class event is possible from 1778 and/or 1781 in the next 24 hours. The position of NOAA 1778 on June 29 at 13:00 UT is: S17W07 (Solar X = 110", Solar Y = -319") 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 1768 was the source of a C7.3 event at 06/28/03:37 UT. 1778 has decayed since the last message losing its beta-gamma magnetic configuration. Another C-class event is possible in the next 24 hour period. The position of NOAA 1778 on June 28 at 12:00 UT is: S17E06 (Solar X = -095", Solar Y = -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.

MM#009 Default HESSI Target Dear RHESSI Collaborators, Solar flare activity remains at a very low level. The target region (NOAA 1775, S26W78) continues to decay. NOAA 1778 has minor emerging flux within its trailing plage area which is adding to its magnetic complexity resulting in an E-type/beta-gamma classification. The target region will switch from 1775 to 1778 today. 1778 was the source of a minor C1.2 event at 06/27/08:14 UT. Another C-class event is possible in the next 24 hours. The position of NOAA 1778 on June 27 at 13:00 UT is: S17E19 (Solar X = -295", Solar Y = -314") 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. All regions on the visible disk are currently in advanced decay phase. Target region NOAA 1775 was able to produce minor events since the last message. The largest was a C1.0 at 06/25/23:57 UT. No significant change in the level of solar flare activity expected anytime soon. The position of NOAA 1775 on June 26 at 13:00 UT is: S26W65 (Solar Y = 769", Solar X = -428") 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 has returned to a very low level. All regions on the visible solar disk are decaying. NOAA 1778 has significantly decayed after it produced the M2.9 and C9.9 events. The most active region in the past 24 hours was NOAA 1775. 1775 is currently classified as a C-type/beta-gamma region. It was the source of two minor C-class events. We will switch from 1778 to 1775 today. Another C-class event is possible. The position of NOAA 1775 on June 25 at 13:00 UT is: S26W53 (Solar X = 678", Solar Y = -434") 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, Southeastern NOAA region 1778 was the source of an isolated M2.9 event at 06/23/20:56 UT. It also produced a C9.9 event at 06/24/11:32 UT. NOAA 1778 is currently classified as a D-type/beta- gamma region with a possible small delta configuration emerging in the southern portion of the leader sunspot. Another M-class event is possible in the next 24 - 48 hours. The position of NOAA 1778 on June 24 at 13:00 UT is: S16E53 (Solar X = -726", Solar Y = -281") 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 remains low. Most of the NOAA numbered regions on the solar disk showed marginal growth in spot area over the previous 24 hours, but little sign of evolution. NOAA 11775 is now classified by NOAA as a beta-gamma/D-type sunspot group, after previously being a beta-delta/D-type sunspot group. The only flare since yesterday's message was a C1.5 (on 22-Jun-2013 at 17:31 UT) originating from NOAA region 11773. The target region will remain the same as yesterday, although it is yet to rotate over the South East limb. C-class activity is possible in the next 24 hours. The approximate position of this region on 23-Jun-2013 at 13:00 UT is: S27E90, ( -841", -428" ) 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 low level. Yesterday's target region NOAA 11777 has increased in spot area, is now classified as a beta/C-type sunspot group, but has been quiet since producing the M2.9 flare on 21-Jun-2013 at 02:30 UT. A new region is located just over the South East limb and was the source of a C2.1 flare on 21-Jun-2013 at 21:00 UT. This region is the return of that previously numbered as NOAA 11762, which produced several M-class events and achieved a maximum magnetic complexity of beta-gamma-delta on its last disk passage. Further C-class events are probable in the next 24 hours, with a small chance for an isolated low M-class event. The approximate position of this region on 22-Jun-2013 at 13:00 UT is: S27E90, ( -841", -428" ) 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 low-to-moderate level. Yesterday's target region has now been designated as NOAA 11777 with an alpha/H-type sunspot group classification. This region appears to have a dominant negative-polarity leading spot with one or two negative-polarity intermediate spots, and a positive-polarity trailing plage (i.e., a reversed magnetic polarity for the southern hemisphere). NOAA 11777 was the source of an M2.9 flare on 21-Jun-2013 at 02:30 UT. C-class activity is expected over the following 24 hours, with a chance for another low M-class event. The position of NOAA 11777 on 21-Jun-2013 at 12:30 UT is: S16E59, ( -780", -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.
