Autumnal Equinox 2016 as seen from Space (animated)

An Equinox is the astronomical event when both the hemispheres have equal duration and amount of sunshine.
Sun would be exactly overhead of the equator.
It happens twice in a year Spring (Summer) equinox (20 March) and Vernal (Autumnal) equinox (22 September).

Here is the view of the beautiful event from space for 22 September 2016.
I have animated it (time series for the day).
Watch the day-night solar terminator move through the earth.
Observe the equal area of sunshine and night on either hemisphere.

The visible imagery is from MeteoSat VISSR (IODC) stationed at 57deg.E longitude above equator in a geostationary orbit.
