autumn moon

September's full moon arrived on the same night as the autumnal equinox. This occurred at 03.09 this morning, marking the official start of autumn in the Northern Hemisphere, as well as the start of spring in the South Hemisphere.

The last time a full moon occurred on the same night as the autumn equinox was 23 September 1991. It won't happen again until 2029.

All that, and - as if on cue- the weather outside this blogger's window went overnight from sunshine to persistent rain.
