RHESSI Major Events

2007

• November 5, around 06:00 UT - We have started to anneal the RHESSI germanium detectors, a process that will keep them offline for between 2 and 3 weeks. Stay tuned for updates.

2006

• August 28, 18:07:47 UT - The analog lower-level threshold on detector G8 was raised to around 6 keV to eliminate excessive low-energy noise. After this date, do not use this detector for imaging or spectroscopy below 10 keV.

• June 9, 05:00 through June 24, 22:00 - During this period RHESSI was pointing off the Sun for Crab Nebula observations. This includes the re-pointing periods on either end. If you are interested in analyzing Crab or solar data in this interval, please contact the instrument team.
