The equinox in the northern hemisphere happens twice a year, around 22 September (autumn equinox) and 20 March (spring equinox). 

The autumn equinox marks the end of summer and the start of autumn as the night becomes longer than the day.

The image was captured by the Flexible Combined Imager (FCI) which is onboard EUMETSAT’s Meteosat Third Generation weather satellite, MTG-I1. 

EUMETSAT is now disseminating pre-operational data from the FCI instrument to weather forecasters around Europe and beyond. Imagery from the FCI can be accessed on EUMETview.
