November 3, 2015 - TIRS Scene Select Mirror Encoder Current Anomaly
At approximately 4:00 PM Central Standard Time (22:00 GMT) Sunday November 1, 2015 the TIRS instrument experienced an anomalous condition related to the instrument's ability to accurately measure the location of the Scene Select Mirror (SSM). The anomaly caused the upper bits of the encoder counts in the ancillary data to be corrupt, resulting in the TIRS bands becoming mis-registered by approximately 500 meters (18 pixels). The encoder was powered off during a morning EROS station pass on Monday November 2. The team is currently gathering and assessing available data and a TIRS Anomaly Review Board (ARB) will be convened within the next day or two to assess options for going forward. (Read More)
