GOES See an Annular Eclipse Shadow in the Southern Hemisphere

By Tim Schmit •

ABI

There are many examples of GOES monitoring the Moon’s shadow on the Earth. This example below occurred on October 2, 2024 and is the CIMSS true color RGB composite from the (Preliminary/Non-operational) GOES-19 ABI. A link to the mp4. And a loop that extends to 21 UTC. Another blog on GOES-19 ABI.

In general, images that have been Raleigh-corrected can make the region of the shadow appear larger. Two examples are below (SSEC GOES-West and East) and the CIRA geoColor.

SUVI

The SUVI also saw the Moon, as it passed in front of the Sun.

More SUVI imagery are available from the SWPC and the UW/SSEC (including RGBs and daily 6-panels).

H/T

These GOES-19 ABI are early images (preliminary and non-operational), beta stage. Both McIDAS-X and geo2grid software was used in generating these images, using data via the UW/SSEC Data Services. More about GOES-16 and GOES-18. T. Schmit works for NOAA/NESDIS/STAR, from Madison, Wisconsin.
