September delivers two eclipses, but neither one will be visible from the U.S. Otherwise, we welcome the arrival of autumn too with the equinox!

September begins with an extravagant display as a total lunar eclipse arrives on the 7th with the Corn Moon. The full eclipse will be visible across Asia parts of Europe. The Western hemisphere will miss out.

We then enter a quieter spell until the new moon on the 21st, which also sees a partial solar eclipse. Though only for a very small area around New Zealand and Antarctica.

The following day, autumn truly arrives with the autumnal equinox on the 22nd. Signalling the beginning of astronomical autumn.
