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

31 Jan '17

Dear RHESSI Collaborators, Solar activity continues at extremely low levels. Yesterday's target region NOAA 12629 has been flare quiet and downgraded to an alpha/H-type configuration. There are currently three numbered sunspot regions on the visible disk, but all of them are mostly quiescent. Today we will watch a newly emerged region (unnumbered yet) in the northern hemisphere crossing the central meridian. This new region is displaying continuous surges in H-alpha images. Low level activities are likely in the next 24 hours. The approximate position of the target on January 31 at 14:30 UT is: N16W02 (30", 340") 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 very low with the GOES soft X-ray flux flat at the ~A8 level since the last message. The target region NOAA 12629 was downgraded to a beta/C-type region, decreasing in the sunspot area and number of spots slightly. 12629 remains the most active region on the visible solar disk. Minor activities are possible in the next 24 hours. The position of NOAA 12629 on January 30 at 14:30 UT is: N15W19 (307", 343") 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 is very low. NOAA 12629 decayed slightly in spot area and number of spots over the previous 24 hours, but has maintained a beta/D-type sunspot group classification. No flares have occurred since the last message. B-class flares may be possible over the following 24-hour period. The position of NOAA 12629 on 29-Jan-2017 at 21:30 UT is: N15W07, ( 112", 348" ) 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. NOAA 12629 was stable in both spot area and number of spots over the past 24 hours, remaining classified as a beta/D-type sunspot group. The only flare since the last message was a C2.8 from NOAA 12627 on 28-Jan-2017 at 20:56 UT. However, NOAA 12629 will stay as the target region because NOAA 12627 is currently rotating over the West limb. B-class flares are probable in the next 24 hours. The position of NOAA 12629 on 28-Jan-2017 at 22:00 UT is: N15E06, ( -97", 347" ) 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 is very low. NOAA 12629 decayed slightly in the past 24 hours, but has remained classified as a beta/D-type sunspot group. This region again produced B-class activity since the last email, this time a single B2.3 flare on 27-Jan-2017 at 15:35 UT. More B-class flares are possible in the following 24-hour period. The position of NOAA 12629 on 27-Jan-2017 at 22:00 UT is: N15E19, ( -306", 341" ) 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 very low level. NOAA 12629 showed some signs of growth over the past 24 hours, and is now classified as a beta/D-type sunspot group. NOAA 12629 was the main source of flares since the last message, producing several B-class flares and the largest event of the period (a B4.1 on 26-Jan-2017 at 04:06 UT). Further B-class flares are likely over the next 24 hours. The position of NOAA 12629 on 26-Jan-2017 at 21:30 UT is: N15E32, ( -503", 330" ) 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 very low level. Yesterday's target region has been designated as NOAA 12629 and classified as a beta/C-type sunspot group. This region continued to show signs of growth and has been the source of 12 B-class flares since the last message, the largest being a B8.5 on 25-Jan-2017 at 21:22 UT. Further B-class activity is likely in the next 24-hour period. The position of NOAA 12629 on 25-Jan-2017 at 22:00 UT is: N15E47, ( -689", 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.

Dear RHESSI Collaborators, The level of solar activity is very low. NOAA 12628 grew in spot area, but increased in longitudinal extent due to separation of its primary leading and trailing spots. A new region has emerged in the North East quadrant over the past 24 hours and, although unclassified, it appears to display a beta/D-type sunspot configuration. This unnumbered region has already produced three B-class flares, the largest being a B5.2 on 24-Jan-2017 at 17:47 UT. Further B-class activity is possible over the following 24 hours. The approximate position of this region on 24-Jan-2017 at 21:00 UT is: N15E62, ( -834", 293" ) 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 very low level. NOAA 12628 remained generally stable since the last message and was classed as a beta-gamma/D-type sunspot group at the beginning of the UT day, although it appears to have now decayed in complexity to a beta/D-type class. No significant flares have been observed in the previous 24 hours. B-class activity is possible over the next 24-hour period. The position of NOAA 12628 on 23-Jan-2017 at 22:00 UT is: N12E09, ( -147", 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, The level of solar activity is very low. NOAA 12628 showed some growth in spot area and magnetic polarity mixing since the last message, and it is currently classified as a beta-gamma/D-type sunspot group. This region produced the only flare in the past 24 hours, a B2.4 on 22-Jan-2017 at 12:23 UT. B-class flares are expected over the following 24 hours, with a chance for C-class. The position of NOAA 12628 on 22-Jan-2017 at 19:30 UT is: N12E25, ( -408", 282" ) 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.
