Maneuvers:
---
Aqua MLC #128 will take place on on 2015/178.
Aqua DMU #97 took place on 2015/142.
Aqua IAM #47 took place on 2015/112.
MODIS Anomalies:
Over the last two Aqua SRCA radiometric mode calibrations (on 2015/110 and 2015/138), we have seen an increase (10-20%) in the measured dn response during the 20W calibration. The lamp voltage during the 20W calibration also shows an increase for the two most recent calibrations, while the current is unchanged. The voltage and current during the 10W calibration are also unchanged. The lamp voltage telemetry point (VR_SR_LAMPS) is measured across all of the lamps. 10W Lamp#1 and #4 are used for the 20W calibration and Lamp #1 is used for the 10W calibration. Also, recent dn trending from the 10W and 1W calibration are showing a noticeable, but not unprecedented, drop for the last two calibrations. This behavior is not considered anomalous.
General Instrument Comments:
FM1 MODIS is in Science Mode. The SVD and NAD are open, the survival
heaters are enabled, and the Black Body is heated to 285 K.
MODIS Telemetry Trends:
The FM1 MODIS instrument telemetry is trending nominally.
