NOAA-9

NOAA-9, also known as NOAA-F, was an American weather satellite operated by the National Oceanic and Atmospheric Administration (NOAA). It was part of a series of satellites called Advanced TIROS-N, being the second of the series.[3] NOAA-9 was launched on an Atlas E rocket on December 12, 1984 from Vandenberg Air Force Base, California, United States.
