MM#009 Default HESSI Target
by Max Millennium Chief Observer 20 Dec '17

20 Dec '17

Dear RHESSI Collaborators, The target region has been designated as NOAA 12692 with a C-type/beta magnetic configuration. 12692 was the source of four low B-class events, the largest one being a B3.0 at 18:14 UT yesterday. 12692 continues to show flux emergence especially in its leading portion. Further B-class activities are expected in the next 24 hours. The position of NOAA 12692 on December 21 at 02:30 UT is: N16E44 (-653", 289") 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 very low levels. The largest event since the last message was a B2.4 at 19:52 UT on December 19 produced by the target plage. The target region is displaying flux emergence. B-class activities are possible in the next 24 hour period. The approximate position of the target on December 20 at 02:30 UT is: N18E58 (-790", 300") 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 remains extremely low with the GOES soft X-ray flux at a background level. The visible solar disk is currently very clear without any spots. No noteworthy activities are expected in the next 24 hours. The approximate position of the target on December 19 at 02:30 UT is: N19E70 (-900", 320") 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 GOES soft X-ray flux has been flat at the ~A4 level. The target was quiescent in the past 24 hours. No noteworthy activities are likely in the next 24 hours. The approximate position of the target on December 18 at 02:30 UT is: N16E60 (-850", 250") 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 at a background level (~A4), and the visible solar disk remains spotless. No noteworthy activities are expected in the next 24 hour period. The approximate position of the target on December 17 at 02:30 UT is: N15E72 (-900", 250") 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 GOES soft X-ray flux has been flat at the ~A4 level since the last message. The target region is still beyond the east limb with some overlying loops visible. Only minor activities are possible in the following 24 hours. The approximate position of the target on December 16 at 04:30 UT is: N14E88 (-920", 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, Solar activity continues at very low levels. The largest events since the last message were two B1.2, one at 2017/12/14/05:10 UT from yesterday's target plage (S07E25) and the other at 2017/12/14/21:28 UT from the northeastern limb. Today we will switch the target to the limb region. Low level activities are likely in the next 24 hours. The approximate position of the target on December 15 at 04:30 UT is: N13E88 (-920", 200") 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 a very low level since the last message. The largest event of the period is a B1.2 at 21:41 UT on December 13 from a plage region (S08E43). Yesterday's target NOAA 12691 has decayed to a plage region, and the solar disk is spotless now. Today the target will switch to another plage region in the southeast quadrant. Only minor activities are likely in the following 24 hours. The approximate position of the target on December 14 at 04:30 UT is: S08E35 (-500", -100") 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 remains at very low levels with the GOES soft X-ray flux flat at ~A4. The target region NOAA 12691 is currently the only region with sunspots on the visible disk. 12691 has been classified as a beta/B-type configuration. Only very minor activities are possible in the next 24 hour period. The position of NOAA 12691 on December 13 at 00:30 UT is: S03E14 (-236", -40") 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 target region has been designated as NOAA 12691 with an alpha/A-type sunspot group. 12691 is showing some small surges in H-alpha images. Only very minor activities are possible in the next 24 hours. The position of NOAA 12691 on December 12 at 00:30 UT is: S03E27 (-443", -43") 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.
