Dear RHESSI Collaborators,
The level of solar activity is very low. Target region NOAA 12680 has grown very slightly in sunspot area, but remains classified as an alpha/H-type sunspot group. This region again produced the largest flare of the period - a C1.5 on 12-Sep-2017 at 19:03 UT. More low C-class activity is possible in the next 24 hours.
The position of NOAA 12680 on 13-Sep-2017 at 13:30 UT is:
N09E31, ( -486", 46" )
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.
