This Week's Scheduled MODIS Activities Not Completed:

None

Upcoming MODIS Events:

Calibrations for January will include one monthly SRCA Full Radiometric (DOY 006), one Blackbody Cycle (DOY 009-012), two screened SDSMs (DOY 006 and 020), one nighttime day mode observation (DOY 005), and one Lunar Roll (DOY 015).

Maneuvers:

None

MODIS Anomalies:

2009/013: On the 013/11:14:51 TD171 contact, there was a late lock condition that was not recognized by the
online team, resulting in a MODIS data loss from 013/10:17:09-10:20:18.

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.
