This Week’s Scheduled MODIS Activities Not Completed:

None

Upcoming MODIS Events:

Calibrations for September will include biweekly SDSM and SRCA Full Spectral.

Maneuvers:

The next Terra MODIS Lunar Calibration Roll will be on DOY 2005/265 (September 22, 2005). The roll angle will be -12.4733 degrees. Data collect will be from 06:28:28 – 06:34:58.

MODIS Anomalies:

None

General Instrument Comments:

MODIS is in Science Mode, using all A-side components, but cross-strapped to Formatter B, with the blackbody maintained at 290K and the Solar Diffuser Door at the Screened position.

MODIS Telemetry Trends:

Nominal telemetry trending is ongoing.

Non-MODIS Significant Events:

On 2005/266 at 14:36:43, TMON 16 tripped causing the science formatting equipment (SFE) to turn off. The FOT successfully turned back on the Science formatter at 19:46:37. Direct Broadcast was also turned back on at 20:40:05. Operations are currently running nominally. There will be no science data between 2005/266/14:36:43 and 19:46:37.
