Maneuvers:

Tue, June 20, 2000 – Drag Makeup Maneuver
Wed, June 21, 2000 – MODIS Roll #1 (2000/173/21:50:10 – 21:56:40), roll degree = -18.0044
Wed, June 21, 2000 – MODIS Roll #2 (2000/173/23:28:43 – 23:35:13), roll degree = -17.4518
Wed, June 21, 2000 – MODIS Roll #3 (2000/174/01:07:16 – 01:13:46), roll degree = -16.9070

MODIS Anomalies:

None.

General Instrument Comments:

MODIS is in Science Mode on the A-side with the SVD and NAD open.

MODIS Telemetry Trends:

Telemetry is nominal.

Non-MODIS Significant Events:

Science Data Losses 159/20:00 – 160/20:00: 46362 CADUs of MODIS (equivalent to 31 sec. Day Mode) lost at 160/16:32:33z due to FOT Ops. Error. FOT failed to implement workaround for very high MODIS Buffer amount (86% full). Lockup loss was overwritten before it could be played back.

Additional setbacks from the Ampex tape drive anomalies at White Sands have resulted in numerous data processing backlogs. The following days are still being processed (in the order listed): 147-150, 131-136
