Started work on MAR1901. Has LETG's and later in week, HETGs. S/C: Expecting OTG patch today; still planning for Monday start of ASVT testing. We lost another thermal sensor on Liquid Apogee Engine #2; no impact on mission. A new SOH was approved at fdb yesterday. From now on the OCC will check that the SIM is at HRC-S position (-99612) whenever altitude is < 60,000 km. Also at fdb, the CPE warm start count issue was closed out. It happens 15 out of 600 tries, randomly. We will no longer run the CAP to check it. New team member is Harold Rice, not Wright as previously reported. Today's eclipse, the 11th and last of the season, will happen at ~1800 GMT. GOT: - SOT: Radiation is very low.
