Since Oct-21, there are two hugh active regions (484 and 486) on the disc. Both have the capability of producing X-flares and, indeed, both did (4 X-class flares in one week!). By the end of the week, both are still very active. However, none of the X-flares were cought by RHESSI for various reasons. Oct-23, 08:40, X5.8, Eclipse, SAA Oct-23, 20:00, X1.1, Lost AGO passes, may be recovered Oct-26, 05:57, X1.2, CPU reset Oct-26, 18:19, X1.2, CPU reset 2. Decimation The decimation was changed from active/active to active/vigorous at Oct-22, 295:03:33:27. 3. Shutter Operations 1-3 at ?? 0-1-3 at ?? 4. Gaps The following known data gaps are due to occured CPU reset (see below) and two vc3 files from Santiago which has not been processed. Those two vc3 files will be fed into the data cue again and therefore the data gap on Oct-23 may be recovered (X1.1 flare).

CPU Reset For reasons we don't know yet, Oct-25 at about 10:30 the CPU on the S/C reset automatically. Caused by this reset the ACS and all ATS commanding didn't work anymore. ... 6.
