On May 20, 2013 as conditions were ripening for severe weather outbreaks in the U.S. Plains, the NOAA Satellite and Information Service placed the GOES-13 satellite into rapid scan operations - meaning that the satellite went from taking imagery every 30 minutes to every 5 minutes. The added frequency greatly assists meteorologists in understanding rapidly evolving weather events, such as the tornadoes that struck Oklahoma that day. This animation shows the GOES-13 visible imagery during the daylight hours of the 20th.
