ACE 2 hr fluence is 1.5e5 vs. threshold 3.6e8. CRM-based orbital fluence is 8.8e3 vs. threshold 1.0e9. Chandra is in the magnetosphere. 4) Quick Look data review (OK unless noted): There were no new quick look data in this shift. 5) The observations of Venus caused the aspect camera to not track some guide stars and fid lights. This is thought to be because of excessive light from Venus on the aspect camera focal plane, even though the star catalogs had been constructed to minimize such problems. Extra DSN comm time was scheduled to monitor Chandra and the ACA data during the Venus observations. Chandra moved to the HR 1099 field without problem following the Venus observations. For the final Venus observation starting on Jan 13 at 1220 UT, a new star catalog has been generated, and continuous DSN coverage has been requested.
