MM#009 Default HESSI Target
by Max Millennium Chief Observer 09 Jul '17

09 Jul '17

Dear RHESSI Collaborators, Solar activity is at a moderate level. NOAA 12665 underwent further flux emergence since the last message, increasing in spot area and number of spots. 12665 continues to be classified as a beta/E-type sunspot group while increasing in flare productivity by being the source of 5 C-class events and an M1.3 on 9-Jul-2017 at 03:09 UT, the largest flare since the last message. Further C-class activity is expected in the next 24 hours, with a chance for an additional low M-class flare. The position of NOAA 12665 on 9-Jul-2017 at 18:00 UT is: S06E28, ( -442", -154" ) 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 low. The target region NOAA 12665 has continued to grow in area and number of spots since the last message. 12665 is now classified as a beta/E-type sunspot group and continues to produce B-class flares, including the largest event since the last message (a B6.8 flare on 8-Jul-2017 at 05:38 UT). More B-class flares are expected in the following 24-hour period. The position of NOAA 12665 on 8-Jul-2017 at 12:00 UT is: S06E45, ( -669", -141" ) 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 12665 remains the only spotted region on the solar disk, and is classified as a beta/D-type sunspot group. This region has undergone significant flux emergence and spot formation since the last message, and shows some signatures of mixed magnetic polarities in its intermediate portion (i.e. gamma Mt Wilson class). NOAA 12665 has continued to produce B-class activity and the largest flare of the period - a C1.0 flare on 7-Jul-2017 at 13:37 UT. Further B-class flares are expected over the next 24 hours, with a chance for low C-class flares. The position of NOAA 12665 on 7-Jul-2017 at 18:30 UT is: S06E54, ( -758", -134" ) 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. The target region has now been numbered as NOAA 12665 and was the source of several B-class flares since the last message. This region was first designated as an alpha/H-type sunspot group but recent images show a beta/D-type configuration. More B-class activity is expected in the following 24-hour period. The position of NOAA 12665 on 6-Jul-2017 at 19:30 UT is: S05E67, ( -868", -104" ) 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 is currently rotating over the South East limb, clearly displaying a mature leading spot and a smaller spot in very close proximity. It is not possible to identify an accurate magnetic classification due to its location close to the limb. B-class flares are likely in the next 24 hours, with a chance for C-class if the region is confirmed as being magnetically complex. The approximate position of this region on 5-Jul-2017 at 18:30 UT is: S05E90, ( -940", -82" ) 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 low. The high-lying loops of NOAA 12664 have now completely disappeared from view over the North West limb and flaring activity has dropped to the low B-class level. STEREO-B images show that a new region with bright EUV coronal loops should soon rotate over the South East limb, with some signatures already visible by AIA. B-class activity is possible in the following 24-hour period. The approximate position of this region on 4-Jul-2017 at 18:00 UT is: S10E90, ( -929", -164" ) 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, Yesterday's target region NOAA 12664 has now fully rotated over the North West limb. Despite this, 12664 was the source of an occulted M1.3 flare on 3-Jul-2017 at 15:37 UT. Although additional occulted major flares are highly unlikely as 12664 is located further around the limb, this region will remain the target for a final 24 hours. B-class flares are expected over the next 24 hours, with a small chance of a high-C-/low-M-class flare. The approximate position of this region on 3-Jul-2017 at 21:30 UT is: N18W90, ( 897", 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, NOAA 12664 was the source of an impulsive ~B3 flare at around 12:30 UT today. The region is now on the western limb and likely retains its alpha configuration. It shall remain the target region for a further 24 hours with chance of an additional isolated low-level event before west limb passage. The position of NOAA 12664 on 2-Jul-2017 at 13:30 UT is: N18W79, ( 881", 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.

Dear RHESSI Collaborators, Solar activity continues at very low levels. NOAA 12664 retains its alpha configuration as it approaches the western limb. It shall remain the target region although no increase in activity is expected over the next 24 hours. The position of NOAA 12664 on 1-Jul-2017 at 15:30 UT is: N17W67, ( 831", 257" ) 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.
