HRC total rates about 165 per sec, good rates ~75 per sec. 14:59 LOS Status essentially unchanged. Descending through 113932 km. ACIS focal plane temperature -119.7. NOTES/ISSUES/PROBLEMS As reported yesterday in SOT shift report M605, CAP 709 was run and successfully inserted the LETG. From the 9am status meeting: 8 supports over the weekend, all data current. On-board command loads good through 082:02:00. Two more segments to be uploaded to complete the MAR1901c loads. A VCDU rollover is expected around 081:03:21. Mission planning products for MAR2601 expected out today for first load review tomorrow. An LETG calibration observation slipped from the MAR1901 loads can't go in the MAR2601 load, so is being scheduled for the APR0201 week. Despite the grating software patch tests and the original blackout of grating operations that week, it is thought the LETG observation can be fit. ASVT testing of the grating patches resumes today at 11:30am, for most of the rest of the day.
