Dear RHESSI Collaborators,

The level of solar activity continues to be low. NOAA 12537 began to decay over the past 24 hours but remains classified as a beta/D-type sunspot group. Newly numbered region NOAA 12539 produced the largest flare since the last message, a C1.2 on 30-Apr-2016 at 10:40 UT. This region was initially classified as a beta/C-type sunspot group but it now appears to have some magnetic polarity mixing (i.e., a beta-gamma classification). C-class flares are probable over the next 24 hours.

The position of NOAA 12539 on 30-Apr-2016 at 20:30 UT is:

N17E40, ( -584", 329" )
