RHESSI Tohban report, 22-Nov-2007 to 28-Nov-2007 Albert Y. Shih, ayshih@ssl.berkeley.edu 1. Solar Activity The Sun was extremely quiet. Active regions 10975 became numbered on November 25. 2. Memory Management The SSR fill level has not been a problem. 3. Data Gaps N/A 4. Spacecraft Operations The detectors were progressively turned on starting November 27. Detector 2 exhibited continuous arcing once it was pushed to 500 V, and even decreasing the HV did not stop the arcing until 100 V. Eventually detector 2 was turned off and left that way in the hope that it will recover. All other detectors are now operating at higher voltages than before the anneal. Preliminary looks at the data are promising, and suggest that the detectors are at least as healthy as the 2005 era. 5. Next Tohban: Hugh Hudson
