Product Anomaly, NOAA-17 AVHRR Scan Motor Degradation, Issued: September 29, 2010 1445 UTC

Topic: NOAA-17 AVHRR Scan Motor Degradation

Date/Time Issued: September 29, 2010, 1445 UTC

Product(s) or Data Impacted: NOAA-17 AVHRR

Date/Time of Initial Impact: September 28, 2010, 1839 UTC

Date/Time of Expected End:Unknown

Length of Event: Until Further Notice

Details/Specifics of Change: NOAA-17 AVHRR Scan motor current increased to above 271.0 mAmps
which caused the scan lines to be out of synchronization. This in effect produces no good images and
will continue until the current returns to nominal level below 240mAmps.

The first orbit experienced a significant degradation was D10271.S1839.E2034.B4294546.
