Autumnal equinox

 

The Autumnal equinox this year was at September 23 03 09 UTC.

This is September 22 20 09 Pacific time or 8.09 pm Wednesday

Not only is it full moon but it is also another special day of the year, this event only happens once per year and it is the only
time of the year when Mean Civil time and Sidereal Time are equal.
A special day for those lucky few with both Sidereal and Mean time timekeepers.
