A total solar eclipse occurred on 20 March before sunrise over the USA. Its appearance on visible imagery from Meteosat-10 was documented here and here. Did GOES-13 also view this event? The imagery above, half-hourly from 0845 through 0945 UTC, shows evidence of darkening (the lunar shadow) initially near 40 N, then a very dark slice in the atmosphere at 0915 UTC and a hint of darkness at 0945 UTC at the extreme limb of the satellite, beyond Iceland. Note also how the terminator in the image, the boundary between day and night, is parallel to longitudinal lines. Happy Equinox!
The shadow of totality was also captured on a NOAA-18 AVHRR 0.86 µm visible channel image at 0907 UTC (below). The shadow extends out over the Atlantic Ocean well to the northeast of Newfoundland.
