MM#009 Default HESSI Target
by Max Millennium Chief Observer 30 Apr '17

30 Apr '17

Dear RHESSI Collaborators, The target region NOAA 12653 produced an isolated B3 flare at 00:12 UT on April 30, which was associated with a weak CME (seems to be not Earth-directed). 12653 retains its alpha/H-type sunspot group, and shows flux emergence in the leading spots. Further B-class activities are possible over the following 24 hours. The position of NOAA 12653 on April 30 at 13:30 UT is: S09W41 (618", -96") 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 the background level. There are three numbered sunspot regions on the visible disk currently, but none of them produced noteworthy events over the past 24 hours. The target region NOAA 12653 remains an alpha/H-type configuration. Low activities will continue in the next 24 hours. The position of NOAA 12653 on April 29 at 19:30 UT is: S09W32 (500", -89") 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 extremely low levels with the soft X-ray flux flat at the ~B1 background. Yesterday's target region NOAA 12652 has decayed to be spotless. Today the target will switch to NOAA 12653, which has an alpha/H-type sunspot group. No noteworthy activities are expected in the next 24 hours. The position of NOAA 12653 on April 28 at 13:30 UT is: S09W14 (228", -78") 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 an extremely low level. There were a few low B-class events emanating from NOAA 12653 (S09W00) and the target region NOAA 12652 in the past 24 hours. 12652 retains an alpha/A-type sunspot group. Low level activity should continue in the following 24 hours. The position of NOAA 12652 on April 27 at 13:30 UT is: N14W34 (518", 291") 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 extremely low levels. The largest event since the last message was a B7.2 at 20:14 UT on April 25 produced by NOAA 12652. Yesterday's target region NOAA 12651 has been flare quiet. Today we will watch NOAA 12652, which has an alpha/A-type configuration. 12652 shows bright dynamic H-alpha plage in H-alpha images. Only B-class level activities are expected in the next 24 hours. The position of NOAA 12652 on April 26 at 13:30 UT is: N13W21 (334", 284") 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 extremely low levels. The largest event of the period was a B2.6 at 22:15 UT on April 24 produced from NOAA 12652. The target region NOAA 12651 decayed significantly and was classified as an alpha/H-type magnetic configuration. We will watch 12651 for a further 24 hours. If possible, also include 12652 within your field of field. No noteworthy events are expected over the following 24 hours. The position of NOAA 12651 on April 25 at 13:30 UT is: N11W17 (274", 255") 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 at a background level. There are currently 3 numbered sunspot regions on the visible disk. The target region NOAA 12651 is mostly unchanged preserving a C-type/ beta magnetic configuration. Only B-class activities are likely in the next 24 hours. The position of NOAA 12651 on April 24 at 13:30 UT is: N12W04 (65",276") 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 of the period was a B3.7 at 03:02 UT on April 23 produced by the target region NOAA 12651. 12651 retains its beta/C-type sunspot group and continues showing flux emergence in its intermediate portion. Only B-class activities are possible over the next 24 hours. The position of NOAA 12651 on April 23 at 13:30 UT is: N12E09 (-146", 277") 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. The largest event since the last message was a B9.6 at 00:22 UT on April 22 produced by the target region NOAA 12651. 12651 has been downgraded to a C-type/beta region. It is still showing flux emergence in its intermediate portion. Some brightenings and surges are also visible in H-alpha images. Further B-class activities are expected with a slight chance of an isolated C-class flare. The position of NOAA 12651 on April 22 at 13:30 UT is: N12E22 (-350", 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.

Dear RHESSI Collaborators, Solar activity continues at low levels. The target region NOAA 12651 has produced a few B-class events (the largest being a B6.2) since the last message. 12651 retains its beta/D-type sunspot group, increasing in sunspot area and number of spots slightly. The coronal loops above this region appear to interact with a small filament at the edge of the region. Additional B-class activities are expected with a chance of an isolated C-class event in the following 24 hours. The position of NOAA 12651 on April 21 at 13:30 UT is: N12E36 (-550", 265") 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.
