Dear RHESSI Collaborators,
The level of solar activity is low. Since yesterday's message, NOAA 11809 was responsible for three C-class events, including the largest flare of the previous 24 hours (a C2.8 flare on 13-Aug-2013 at 11:46 UT). However, yesterday's target region, NOAA 11817, still maintains the largest spot area on disk. The delta spot at its center has separated, but the region still exhibits some evidence for a gamma configuration and the continues to emerge flux within its leading portion. Additionally, nearby NOAA 11819 appears to be strongly magnetically connected and may further destabilise NOAA 11817. C-class activity is likely, with a chance for an isolated low M-class event.
The position of NOAA 11817 on 13-Aug-2013 at 17:00 UT is: S23W02, ( 33", -469" )
