September’s full harvest moon rises tonight, but there’s something special about the lunar machinations this time of year.

Near the fall equinox, which was Saturday, the moon rises each day closer together, according to Earth and Sky. That means instead of a delay between 40 and 50 minutes each subsequent day, it’s more like 30 to 35 minutes.

The higher the latitude, the shorter the time lag. In Alaska, the lag time is just 10 minutes. In Denver it’s 30 minutes.

“No matter where you live worldwide, the moon will appear plenty full to you on both September 24 and 25, lighting up the night from dusk until dawn,” said Earth and Sky columnist Bruce McClure.

In West Palm Beach, moonrise tonight is 7:20 p.m.

Tuesday’s moonrise will be 7:55 p.m..

Wednesday will see the moon rise at 8:41 p.m.

The Harvest Moon is the only Full Moon name which is determined by the equinox rather than a month, according to TimeandDate.com.

Bottom line, look east tonight at 7:20 p.m. for September’s full harvest moon. Go to the beach, or the Intracoastal waterway for a special celestial treat when the moon emerges large and plump over the flat horizon.
