15 April 1999 -- GOES-8 Imager 6.7 Micrometer IR ("Water Vapor")
Super Rapid Scan Operations (SRSO) Test Over the Tropical Atlantic

(this 50-image Java animation sequence will take a minute or two to load...)

This loop of GOES-8 6.7 micrometer InfraRed ("water vapor") includes 1-minute interval Super Rapid Scan Operations (SRSO) imagery during a 3-hour test over the tropical Atlantic Ocean on 15 April 1999. There are some gaps in the 1-minute interval scanning, so the loop will appear to have some small "jumps".

Note the apparent "flicker" in the warmer (less moist) cloud-free regions (darker enhancement); this could be due to signal-to-noise from the 6.7 micrometer IR detectors (noise is around 0.3 degrees K at 230 K).
