MM#009 Default Target Dear Collaborators, The visible solar disk is currently spotless. Solar flare activity is at an extremely low level and is expected to continue at an extremely low level for the next 24 hour period. Target region NOAA 2773 is a large decaying plage.2773 is mostly unchanged and hasn't produced any noteworthy flare events since the C1.1 at 09/26/00:38 UT. The position of NOAA 2773 on September 30 at 06:00 UT is: N27W23 (Solar X = 335", Solar Y = 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.

MM#009 Default Target Dear Collaborators, Solar flare activity is currently at an extremely low level. Target region NOAA 2773 is mostly unchanged. A few micropores are visible on hi-resolution W/L images. The small region located at S21W16 is also displaying some micropores. No significant solar flare events expected in the next 24 hour period. The position of NOAA 2773 on September 29 at 15:30 UT is: N27W14 (Solar X = 207", Solar Y = 336") 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 Target Dear Collaborators, Target region NOAA 2773 produced two minor A-class events since the last message. The largest was an A7.0 at 09/28/02:54 UT. 2773 is currently displaying at few pores. There is a tiny EFR with a two spot B-type/beta sunspot group located at S21W03. No significant solar flare events expected in the next 24 hour period. The position of NOAA 2773 on September 28 at 17:30 UT is: N27W02 (Solar X =030", Solar Y = 332") 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 Collaborators, The target region NOAA 12773 has lost its sunspots again and now the visible solar disk becomes spotless again. No flares have occurred since the last message. 12773 continues to decay with magnetic cancellation occurring in its intermediate portion. Only low-level activities are likely in the next 24 hours. The position of NOAA 12773 on September 27 at 11:30 UT is: N27E11 (-163", 332") 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 Collaborators, The target NOAA 12773 was the source of two B-class flares as well as a C1.1 flare (at 23:59 UT on September 25) during the period. At the beginning of the UT day, 12773 was designated as an Alpha/A-type region, i.e., regaining its sunspots, but now it appears to have lost them again. 12773 continues to decay with magnetic cancellation occurring in its intermediate portion. Additional B-class activities are likely with a slight chance of a low-level C-class flare in the next 24 hours. The position of the target on September 26 at 19:30 UT is: N27E21 (-306", 337") 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 Collaborators, NOAA 12773 has lost its sunspots and become a page region. Now the visible solar disk is spotless again. 12773 has produced several A- and B-class flares since the last message, with the largest one being a B3.4. This region has begun to decay. Only very low-level activities are expected in the next 24 hours. The approximate position of the target on September 25 at 15:30 UT is: N28E39 (-533", 367") 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 Collaborators, The target region has been designated as NOAA 12773, with a beta/B-type magnetic configuration. 12773 produced several A-class flares as well as a B1.3 in the past 24 hours. It continues to emerge positive magnetic fluxes. More A- and also B-class events are probable in the next 24 hours. The approximate position of the target on September 24 at 03:30 UT is: N28E60 (-732", 395") 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 Collaborators, The target region was the source of a few A-class flares in the past 24 hours. It continues to show EUV jets. As this region rotates onto the visible solar disk, its total unsigned magnetic flux and current helicity increase. Further A-class events are expected and some B-class flares are probable in the next 24 hours. The approximate position of the target on September 23 at 07:30 UT is: N27E70 (-750", 430") 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 Collaborators, The target limb region has produced a few A- and B-class X-ray events (the largest one being a B1.7 at 16:34 UT on September 21) since the last message. This region is still too close to the limb to ascertain its magnetic configuration. Further low-level (A- and B-class) activities are expected in the following 24 hours. The approximate position of the target on September 22 at 07:30 UT is: N27E82 (-780", 430") 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 Collaborators, Solar activity has increased since the last message. The target limb region was the source of numerous A-class events as well as a few B-class flares, with the largest one being a B4.3 at 12:24 UT today. This region continues rotating onto the visible solar disk. It is still hard to determine the magnetic configuration. Additional B-class flares are expected, with a chance of an isolated C-class flare in the next 24 hours. The approximate position of the target on September 21 at 12:00 UT is: N28E86 (-790", 430") 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.
