Dear RHESSI Collaborators,

The level of solar activity is low. The largest flare since the previous
message was
a C3.2 flare on 28-Jul-2013 at 12:21 UT released from the area between NOAA
11805 and 11800. Since yesterday this localised complex of sunspot groups
(including NOAA 11805, 11800 and decayed regions 11803, 11798, and 11799)
has
been resposible for multiple C-class flares. There is currently a ~C3 flare
in
progress from the region. Although there are also two currently emerging
bipole
regions on disk (near N30W10 and N15E60), the target region is still
designated as
11800, as it is clearly still unstable. But, if the observer's field of
view is large
enough, it should also include NOAA 11805, which appears to be strongly
magnetically connected. Tomorrow the target will likely switch to one of
the newly
emerging bipole regions. Further high B-class activity is expected with a
chance for
a further C-class event.

The position of NOAA 11800 on 29-Jul-2013 at 17:00 UT is:
S08W83, ( 930", -141" )
