Details/Specifics of change:On 01/28/2019 the S-NPP VIIRS suffered an uncorrectable Error Detection and Correction (EDAC) error. After further analysis by OSPO mission operations and the vendor it was recommended to perform a controlled control processor (CP) reset.The error occurred within a portion of the memory that manages the data buffers for the 1394 bus.This indicates potential for data corruption. VIIRS hardware is not in any danger and J1 Data can be used as a comparison any obvious problems with the data present themselves. Performing the VIIRS CP reset and recovery during cited times above will rectify the error.
