MM#009 Default HESSI Target
by Max Millennium Chief Observer 30 Sep '17

30 Sep '17

Dear RHESSI Collaborators, The GOES soft X-ray flux remains at a background level. Only two B2 events were produced by NOAA 12682 (S09E04) in the past 24 hours. The target region NOAA 12683 is mostly unchanged, retaining its alpha/H-type sunspot group. Quiet conditions should continue in the next 24 hour period. The position of NOAA 12683 on September 30 at 07:30 UT is: N14E17 (-272", 126") 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 largest event since the last message was a B2.9 at 14:09 UT on September 28 produced by NOAA 12681 (S11W30). The target region NOAA 12683 remains its alpha/H-type configuration, slightly increasing in sunspot area. Only very minor activities are likely in the following 24 hours. The position of NOAA 12683 on September 29 at 07:30 UT is: N14E22 (-349", 128") 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 with the soft X-ray flux flat at ~B1. The target region NOAA 12683 was flare quiet since the last message and has been downgraded to an alpha/H-type classification but increasing in sunspot area. Only very low level events are possible in the next 24 hour period. The position of NOAA 12683 on September 28 at 07:30 UT is: N13E39 (-589", 128") 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 largest event since the last message was a C1.8 at ~01:00 UT today produced by NOAA 12683. 12683 was also the source of several B-class events. Today we will switch the target to this region, which was classified as a beta/D-type sunspot group. B- and low C-class activities are likely in the following 24 hours. The position of NOAA 12683 on September 27 at 07:30 UT is: N12E56 (-777", 135") 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 a very low level. There are currently three active regions with sunspots on the visible disk, all of which produced some B-class events. The target region NOAA 12682 remains its alpha/H-type sunspot group, but increases in spot area. 12682 shows some mixed polarities in its intermediate portion as well as some small jets. B-class activities are expected and low C-class flares may be possible in the next 24 hours. The position of NOAA 12682 on September 26 at 07:30 UT is: S10E55 (-773", -230") 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 very low level. The largest event since the last message was a B5.7 at 02:14 UT today produced by NOAA 12681. The target region has been designated as NOAA 12682 with an alpha/H-type classification. 12682 shows some small jets/eruptions. Low activities are possible in the next 24 hours. The position of NOAA 12682 on September 25 at 07:30 UT is: S09E67 (-870", -193") 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. The region previously designated as NOAA 12673 has rotated over the South East limb and is expected to be numbered at the end of today as NOAA 12682. This region produced several low B-class flares in the past 24 hours, but is too close to the limb to accurately determine its magnetic complexity. C-class flares are possible in the following 24-hour period, with a small chance for an M-class flare. The approximate position of this region on 24-Sep-2017 at 16:00 UT is: S10E80, ( -928", -185" ) 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. Solar background soft X-ray flux has gradually increased over the last 48 hours from mid-A-class to low-B-class. This is due to the X-class producing region that was previously designated as NOAA 12673 rotating up to the East limb from the far side. C-class activity is possible in the next 24 hours, with a small chance for M-class if old NOAA region 12673 has retained its magnetic complexity. The approximate position of this region on 23-Sep-2017 at 18:30 UT is: S09E90, ( -944", -148" ) 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 12680 has rotated up to the North West limb, while NOAA 12681 is clearly visible on the disk. 12681 has remained stable in terms of spot area and number of spots, again being classified as an alpha/H-type sunspot group. No flares have occurred in the past 24 hours. Low B-class flares are possible in the following 24-hour period. The position of NOAA 12681 on 22-Sep-2017 at 13:30 UT is: S13E53, ( -745", -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, The level of solar activity is very low. Yesterday's target region has been designated as NOAA 12681 and classified as an alpha/H-type sunspot group. This region decreased in flare productivity, but was the source of a B1.0 flare on 20-Sep-2017 at 20:00 UT. More B-class activity is possible over the next 24 hours. The position of NOAA 12681 on 21-Sep-2017 at 13:30 UT is: S12E65, ( -848", -246" ) 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.
