MM#009 Default HESSI Target
by Max Millennium Chief Observer 28 Feb '15

28 Feb '15

Dear RHESSI Collaborators, Solar activity has increased to C-level since the last message. A newly emerged region in the southeast quadrant NOAA 12294 was the source of C5.6 flare at 08:58 UT today although the region appears to have decayed since then. The target region NOAA 12293 has developed a delta configuration in its leader spot and may also produce increased activity over the next 24 hours. The position of NOAA 12293 on 28-Feb-2015 16:35 at UT UT is: N06E19, ( -314", 215" ) 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, Quiet-Sun conditions prevail with NOAA 12290 continuing to decay. Some low B-level events have emanated from NOAA 12293, a newly emerged beta region in the northeast quadrant. This shall be the new target region with further low level events possible if the region continues to develop. The position of NOAA 12293 on 27-Feb-2015 at 12:35 UT is: N06E35, ( -554", 199" ) 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 X-ray flux remains at background levels. NOAA 12290 continues to show signs of decay and has been inactive since the last message. It shall remain the target region although no significant increase in activity is expected over the next 24 hours. The position of NOAA 12290 on 26-Feb-2015 at 10:04 UT is: N19W28, ( 431", 415" ) 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 continued at very low levels since the C1.4 flare yesterday. The target region NOAA 12290 has remained quiescent and has begun to show signs of decay in its trailing portion. No significant activity is expected over the next 24 hours. The position of NOAA 12290 on 25-Feb-2015 at 10:04 UT is: N20W14, ( 221", 440" ) 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. The target region NOAA 12290 remains quiescent and unchanged as it crosses the central meridian. The C1.4 flare that occurred at ~10:00 UT today is likely to be associated with the CME eruption off the southeast limb. Possibility of minor events from the target region over the next 24 hours. The position of NOAA 12290 on 24-Feb-2015 at 10:04 UT is: N20W01, ( 15", 443" ) 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 largest event since the last message was a C1.1 flare at 00:10 UT from NOAA 12288, which is now beyond the western limb. The target region NOAA 12290 continues to develop in size but retains its beta/D-type configuration. Further B-level flares expected with chance for some low C-level activity. The position of NOAA 12290 on 23-Feb-2015 at 10:04 UT is: N20E12, ( -190", 440" ) 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 region 12287 produced no activity in the past 24 hours while maintaining spot area and number of spots. This region has been reclassified as a beta/D-type sunspot group. NOAA 12209 has grown marginally in spot area over the previous 24 hours and is also classified as a beta/D-type sunspot group. The largest magnitude flare of the past 24 hours (a B7.1 on 21-Feb-2015 at 18:20 UT) was produced from a location slightly westward of this region. Further B-class activity is expected over the next 24 hours. The position of NOAA 12290 on 22-Feb-2015 at 16:30 UT is: N19E22, ( -345”, 420” ) 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 region 12286 produced more C-class activity in the past 24 hours as it rotated over the South West limb. NOAA 12287 has decreased marginally in both spot area and number of spots, being reclassified as a beta/C-type sunspot group. B-class flares are expected over the next 24 hours. The position of NOAA 12287 on 21-Feb-2015 at 14:00 UT is: N14W12, ( 192”, 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, Solar activity remains at a low level. NOAA region 12286 displayed the greatest flare activity in the past 24 hours, producing C-class events (a C1.1 on 19-Feb-2015 at 17:42 UT and a C1.5 on 20-Feb-2015 at 10:01 UT). However, this region has now rotated up to the South West limb. Yesterday’s target, NOAA 12287, has maintained spot area and increased marginally in number of spots, remaining classified as a beta/D-type sunspot group. This region also displayed activity since yesterday’s message, producing a B6.1 flare on 20-Feb-2015 at 01:06 UT. Further B-class flares are expected over the next 24 hour period, with a reasonable chance for further low C-class activity. The position of NOAA 12287 on 20-Feb-2015 at 13:00 UT is: N14E01, ( -14”, 349” ) 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 12282 has again decreased marginally in spot area and number of spots as it rotates further towards the North West limb. This region remains classified as a beta/C-type sunspot group and produced the largest magnitude event in the previous 24 hours (a C3.5 flare on 18-Feb-2015 at 21:53 UT). Yesterday’s target region is now designated as NOAA 12287 and has formed several more small spots since yesterday’s message. B-class flares are expected over the next 24 hours, with a chance for more C-class activity. The position of NOAA 12287 on 19-Feb-2015 at 14:00 UT is: N14E13, ( -217”, 346” ) 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.
