Dear RHESSI Collaborators,

Solar activity has increased dramatically. NOAA 12644 has produced two mid M-class flares in the past 24 hours, with an M5.4 currently in progress (07:50 UT). At this time we are issuing a Major Flare Watch with NOAA 12644 as the target region. The region is approaching the western limb and appears to be increasing in magnetic complexity. Further intermediate level activity expected (from NOAA 12645 as well), with chance for additional M-level activity in the next 24 hours.

The position of NOAA 12644 on 2-Apr-2017 at 07:30 UT is:

N12W56, ( 779", 257" )

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.
