16:16 - Topup has been temporarily suspended. Vadim Sajaev opened RT feedback loops, collected SR data for ~15 seconds, and closed RT feedback loops. This was done as a part of investigation into 100Hz RMS beam motion in the vertical plane reported at 4-ID. Topup has been restarted. There was excessive RMS beam motion from 16:15 to 16:16.
