GOES-16 (GOES-East)<\/em> Near-Infrared “Snow\/Ice” (1.61 \u00b5m<\/strong><\/a>) images (above)<\/strong><\/em> showed the shadow of a total solar ecliipse<\/strong><\/a> in the Southern Hemisphere on 04 December 2021. Even though the 1.61 \u00b5m imagery is at a lower (1 km) spatial resolution, it provided better contrast than higher-resolution (0.5 km) 0.64 \u00b5m<\/strong><\/a> “Red” Visible imagery, helping to highlight the shadow (below)<\/strong><\/em>. Note that the shadow passed over the Antarctic Peninsula<\/strong><\/a>.<\/p>\n

GOES-16 CIMSS True Color RGB images created using Geo2Grid<\/strong><\/a> (below)<\/strong><\/em> provided another view of the eclipse shadow’s progression.\u00a0<\/p>\n

In addition, portions of the solar eclipse shadow could be seen in True Color RGB images from Suomi-NPP and NOAA-20, as viewed using RealEarth<\/strong><\/a> (below)<\/strong><\/em>.<\/p>\n
