Dear RHESSI Collaborators,
Solar activity is at low-to-moderate levels. A new region that is currently rotating over the South East limb produced 2 low M-class flares over the past 24 hours (an M1.1 on 17-Oct-2015 at 20:09 UT and an M1.5 on 17-Oct-2015 at 20:35 UT), but remains too close to the limb to determine an accurate magnetic complexity. In the same period NOAA 12434 initially grew in spot area and developed into a beta-gamma-delta/D-type sunspot group classification. However, the opposite polarity umbrae that made up the delta-spot have appeared to drift apart and no longer have connected penumbrae. NOAA 12434 has continued to produce C-class activity since the last message, the largest being a C4.5 on 17-Oct-2015 at 12:31 UT. More C-class flares are expected over the next 24-hour period, with a chance for low M-class events.
The position of NOAA 12434 on 18-Oct-2015 at 18:30 UT is:
S10E10, ( -162", -259" )
