Dear RHESSI Collaborators,

The level of solar activity is low. Yesterday's target region 11805 has rotated to the West limb and has significantly decreased in activity. On the other hand, a new region, NOAA 11809, has rotated onto the East limb. Meanwhile, a new bipole is currently emerging at around N05E45, which may act to destabilise both NOAA 11809 and nearby NOAA 11808. NOAA 11809 appears to have the strongest and most complex sunspot configuration, although it is difficult to determine the precise surface magnetic field morphology, currently. Considering soft X-ray images, NOAA 11809 is the most active and was responsible for at least one C-class event (a C1.5 on 31-Jul-2013 at 05:18 UT) since the last message. Further low C-class activity is expected, with a chance for an isolated high C-class event.

The position of NOAA 11809 on 31-Jul-2013 at 17:30 UT is: N14E69, ( -859", 195" )
