Dear RHESSI Collaborators,

Solar activity continues at very low levels. The largest event since the last message was a C1.9 at 05:13 UT today produced by the target region NOAA 12331. The large filament at the northeast limb was erupted at ~14:00 UT today, which was associated with a two-ribbon flare and a CME. NOAA 12331 has been downgraded to a beta region. It will be the primary target for one more day, with low-level activity possible in the next 24 hours. NOAA 12333 (N20W09) shows some signs of growth, with a chance of low-level activity.

The position of NOAA 12331 on April 28 at 15:35 UT is:

S09W82 (Solar X = 932", Solar Y = -138")
