MM#009 Default HESSI Target

MM#009 Default HESSI Target Dear RHESSI Collaborators, NOAA 2665 has rotated well beyond the southwestern limb. 2665 was the source of limb occulted minor C-class events in the past 24 hours. The largest was a C2.8 at 07/19/00:07 UT. It is still possible that 2665 could produce another interesting limb event in the next 24 hour period. The current visible solar disk is spotless with only a few decaying plage remnants. The position of NOAA 2665 on July 19 at 15:30 UT is: S06W90 (Solar X = 939", Solar Y = -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.

MM#009 Default HESSI Target Dear RHESSI Collaborators, NOAA 2665 produced several C-class events in the past 24 hours. The largest was a C2.1 at 07/18/00:40 UT. 2665 is now located almost completely beyond the southwestern limb but there is a chance of another minor limb occulted event in the next 24 hour period. The position of NOAA 2665 on July 18 at 15:30 UT is: S06W91 (Solar X = 938", Solar Y = -096") 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, NOAA 2665 has continued in decay phase losing almost all of its trailing sunspots. 2665 was the source of numerous B-class events and two C-class events since the last message. The largest C-class event was a C2.3 at 07/17/03:28 UT. B-class activity probable with the chance of another C-class event before 2665 completes west limb passage. The position of NOAA 2665 on July 17 at 15:30 UT is: S06W79 (Solar X = 921", Solar Y = -112") 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. NOAA 12665 has continued in decay phase, decreasing in spot area and number of spots to be designated a beta/D-type sunspot group. 12665 continues to produce C-class flares, including the largest event of the period (a C5.8 on 15-Jul-2017 at 19:26 UT). More C-class activity is expected over the next 24 hours. The position of NOAA 12665 on 16-Jul-2017 at 16:30 UT is: S05W66, ( 861", -112" ) 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 has slowed in decay by maintaining spot area while decreasing in number of spots. 12665 has remained designated as a beta/E-type sunspot group and continued to produce C-class activity, including the largest event since the last message (a C1.7 on 15-Jul-2017 at 00:20 UT). Further C-class flares are probable over the following 24-hour period, with a small chance for a low M-class flare. The position of NOAA 12665 on 15-Jul-2017 at 11:00 UT is: S06W49, ( 711", -146" ) 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 moderate. NOAA 12665 has shown further signs of decay with increased number of spots and continued decrease in area. The target region has remained designated as a beta/E-type sunspot group by NOAA and produced a long-duration M2.4 flare with a CME on 14-Jul-2017 at 01:07 UT. C-class flares are expected over the next 24 hours, with a chance for another low M-class flare. The position of NOAA 12665 on 14-Jul-2017 at 12:00 UT is: S07W37, ( 561", -171" ) 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. Two newly spotted regions have emerged in the Northern hemisphere, with only one being numbered by NOAA as region 12666. This region has remained inactive while the smaller new, unnumbered spot group (at approximately N13W68) produced a C8.4 flare on 13-Jul-2017 at 20:01 UT. NOAA 12665 has again decreased in spot area and magnetic complexity, now being designated as a beta/E-type sunspot group. NOAA 12665 continued producing B-class flares and remains the target region. B-class flares are expected in the following 24-hour period, with a good chance for additional C-class flares. The position of NOAA 12665 on 13-Jul-2017 at 21:30 UT is: S06W29, ( 456", -159" ) 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 12665 has decreased marginally in spot area and number of spots in the past 24 hours. This region has remained classified as a beta-gamma/E-type sunspot group but appears to be reducing in magnetic polarity mixing. NOAA 12665 has reduced in flare productivity, but was still the source of the only flare since the last message, a C1.2 on 11-Jul-2017 at 20:18 UT. B-class flares are expected in the next 24 hours, with a good chance for additional C-class flares. The position of NOAA 12665 on 12-Jul-2017 at 17:30 UT is: S06W13, ( 207", -165" ) 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 12665 has stabilised in terms of spot area and number of spots over the past 24 hours. This region remains classified as a beta-gamma/E-type sunspot group, but appears to have reduced its magnetic polarity mixing to beta class. NOAA 12665 has produced 5 B-class flares since yesterday's message, including the largest of the period (a B8.5 flare on 11-Jul-2017 at 12:57 UT). Further B-class activity is expected in the following 24 hours, with a good chance for C-class flares. The position of NOAA 12665 on 11-Jul-2017 at 18:00 UT is: S06E01, ( -17", -165" ) 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. NOAA 12665 has continued to emerge new magnetic flux over the previous 24 hours, increasing in spot area, number of spots and magnetic classification to be designated as a beta-gamma/E-type sunspot group. 12665 has also continued to produce B-class flares and the largest event since the last message, a C1.5 on 10-Jul-2017 at 00:00 UT. Additional C-class flares are expected in the next 24 hours. The position of NOAA 12665 on 10-Jul-2017 at 18:30 UT is: S06E14, ( -224", -161" ) 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.
