20 March 2017
The Equinox was at 10:29 GMT or 6:29 AM EDT this morning, and yes it is visible from space. The terminator between light and dark is exactly due north/south on the equinoxes, and you can see that this is indeed the case from the image above. The line will tilt to the right at exactly 23.5 degrees by the summer solstice.
