This Month's Upcoming MODIS Events:
---
February's routine activities include a SDSM_Closed on 2017/052, a Blackbody_Cycle on 2017/032-035, a PV_Ecal on 2017/049, an SRCA_Radiometric on 2017/037, an SRCA_Spectral on 2017/053, and a Lunar_Roll on 2017/046.
Non-routine activities include a Lunar Roll on 2017/016.
Maneuvers:
---
Terra Lunar Roll took place on 2017/046.
Terra DMU #99 took place on 2017/019.
Terra IAM #48 took place on 2017/054.
MODIS Anomalies:
---
During the SRCA Spectral Calibration, three temperature telemetry points went high yellow. These telemetry mnemonics are MOD_TP_PCFAM_RADIATR, MOD_TP_MF_TOP_BY_KM1, and MOD_TP_MF_TOP_BY_KM3. A few hours after the end of the Spectral Calibration, these temperatures went back below the high yellow alarm limit and then back to nominal levels. More investigation is necessary, but this anomaly appears to be innocuous.
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.
