OA-19: SRCA Full Radiometric Calibration.
Data collection 21:43:31-21:58:54 (centered on S/C Night)

None
MODIS Anomalies:
2009/107
The MODIS telemetry point MOD_VR_PVSM_P30V went just bellow the lower yellow limit of 26.6 with value of
26.34 at 15:22:15 and returned to within limits with a value of 27.4617 at 15:23:17.
2009/109
The MODIS telemtry point SS_CP_UART_Reset went out of bounds with a value of 127 at the beginning of a contact
at 01:33:38. The yellow upper limit for this telemetry point was 126. After consulting with Joe Auchter,
we have concluded that this was probably a random upset and not indicative of other problems with the CP. We
will adjust the yellow upper limit to 127 to ensure that the point will flag yellow if and when it increments
again.
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.
