Total solar eclipse of 21 August 2017 – a satellite perspective
* GOES-16 data posted on this page are preliminary, non-operational and are undergoing testing*
GOES-16 CONUS Sector images (at 5-minute intervals)
GOES-16 Mesoscale Sector images (at 1-minute intervals)A “floating” Mesoscale Sector provided 1-minute imagery during the eclipse (above).
Polar-orbiting satellite images (Terra MODIS, and Suomi NPP VIIRS)A toggle between Terra MODIS Visible (0.65 µm), Land Surface Temperature product, Shortwave Infrared (3.7 µm) and Infrared Window (11.0 µm) images (above) showed the eclipse shadow as it was centered over western Nebraska around 1748 UTC. Without a time series of MODIS Land Surface Temperature product images, it is difficult to gauge the exact amount of surface cooling brought about within the shadow of totality. A large-scale high resolution Terra MODIS Visible image is available here (courtesy of Liam Gumley, SSEC). A comparison of Suomi NPP VIIRS Visible (0.64 µm), Day/Night Band (0.7 µm) and Infrared Window (11.45 µm) images (above) showed the shadow center over eastern Tennessee around 1833 UTC. A closer comparison of Day/Night Band and Infrared images (below) revealed the presence of cloud features that made it difficult to see a signature of any city lights that may have come on in the Nashville TN (KBNA) metropolitan area.
