Dear RHESSI Collaborators,

Solar activity is at a low level. NOAA region 11818 has maintained
spot area and decreased in number of spots as it rotates towards the
West limb, producing 2 C-class events since yesterday's message (the
largest being a C1.6 flare on 20-Aug-2013 at 09:57 UT). This region
is now classified by NOAA as an alpha/H-type sunspot group, but may
still contain the remnants of the delta spot on the northern edge of
the leading spot. NOAA region 11820 has undergone a period of rapid
flux emergence over the past 24 hours, growing significantly in both
spot area and number of spots, as well as developing a mixed polarity
intermediate spot region. C-class events are likely in the following
24 hours, particularly if 11820 continues to emerge new flux.

The position of NOAA 11820 on 20-Aug-2013 at 13:00 UT is:

S12W26, ( 411", -297" )
