MM#009 Default HESSI Target
by Max Millennium Chief Observer 31 Jul '17

31 Jul '17

Dear RHESSI Collaborators, NOAA 12669 has remained quiescent since the last message, and has since been downgraded to an alpha configuration region. A new active region approaching the eastern limb has produced several B-class flares over the past 24 hours, including a B9.2 event at 09:02 UT today. This shall be the new target region. Further B-level activity expected, and C-level activity possible, as the region rotates onto the visible hemisphere. The approximate position of the target region on 31-Jul-2017 at 19:30 UT is: S06E83 = (-933", -110") 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 visible solar disk remains spotless. The target plage region produced a B1.5 at 21:07 UT on July 27, the only flare event of the period. A non-Earth-directed CME was launched around 05:30 UT on July 28 probably from a region at the farside. The target region appears to be stable. Only very low activity is expected over the next 24 hours. The approximate position of the target on July 28 at 15:30 UT is: N07E20 (-400", 80") 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 an extremely low level. The GOES soft X-ray flux has been flat at ~A4 since the last message. The visible solar disk remains spotless. The target plage region is mostly unchanged. No noteworthy activity is likely over the following 24 hours. The approximate position of the target on July 27 at 13:30 UT is: N04E36 (-580", 90") 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 extremely low with the soft X-ray flux flat at a background level. Currently the visible solar disk appears to be spotless, though there was a new sunspot region designated as NOAA 12668 (N03W36) at the start of the UT day. The target plage region was somewhat stable and did not produce any flares. No notable activity is expected in the next 24 hour period. The approximate position of the target on July 26 at 13:30 UT is: N04E47 (-700", 10") 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 an extremely low level with the GOES soft X-ray flux flat at ~A5.4. The visible solar disk remains spotless. The target plage region has been flare quiet and mostly unchanged since the last message. Only very minor activity is possible in the following 24 hours. The approximate position of the target on July 25 at 15:30 UT is: N04E60 (-780", 30") 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. The largest event since the last message was an occulted B1.3 at 22:31 UT on July 23 produced by the target region. The target region is still beyond the northeastern limb. Low level activities are likely in the next 24 hours. The approximate position of the target on July 24 at 15:30 UT is: N04E75 (-890", 50") 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 very low. The current visible solar disk is spotless. A small portion of the target filament disappeared in the past 24 hours. The target will switch to a region located mostly beyond the northeastern limb. This region was the source of a limb occulted minor B1.5 event at 07/23/07:35 UT. Additional B-class activity is possible in the next 24 hour period. The approximate position of the target on July 23 at 14:45 UT is: N05E90 (Solar X = -941", Solar Y = 082") 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 an extremely low level. The visible solar disk is spotless. The target filament has lost almost all of its southern portion and the northern portion is currently quiescent. No significant solar flare activity expected in the next 24 hour period. The position of the filament target on July 22 at 06:30 UT is: N30E22 (Solar X = -308", Solar Y = 406") 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 to be very low. The single event since the last message was a B1.7 at 07/20/23:15 UT produced by NOAA 2665 located about 3 days beyond the southwestern limb. The current background x-ray flux is flat at the A4 level. The visible solar disk is spotless. The target filament continues in an active phase. No significant solar flare activity expected anytime soon. The position of the target filament on July 21 at 06:30 UT is: N28 E39 (Solar X = -526", Solar Y =388") 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 2665 located well beyond the southwestern limb produced a limb occulted C1.3 event at 07/19/00:01 UT. The current visible disk is spotless and 2665 is too far beyond the west limb to continue to be the target. The target will switch to an active filament located along the magnetic inversion line of the reversed polarity weak magnetic field of old NOAA 2664. Solar flare activity is expected to be very low in the next 24 hour period. The position of the filament target on July 20 at 05:15 UT is: N27E53 (Solar X = -674", Solar Y = 386") 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.
