Dear Collaborators,
The largest event since the last message was a long duration B9.7 flare at 04/17/16:21 UT produced by a south-east limb region (S21E88). This limb region has been flare quiet since then. The target region NOAA 12816 was the source of five B-class flares (the largest one being a B4.1) during the period. 12816 retains its beta/C-type configuration but increases in current helicity significantly (based on the SHARP data). More B-class flares are expected with a chance of a C-class event in the next 24 hours.
The position of NOAA 12816 on April 18 at 11:30 UT is:
S24E39 (-550", -324")
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.
