If you've been outside the last two nights you probably noticed the harvest of moonlight casting a silvery glow on the browning foliage.
As bright as it has been, the moon is about to pick it up a notch, and for the first time in 20 years it will become full on the first full day of autumn.
It should rise through the clouds brilliantly in the eastern sky at 6:20 this evening, or 28 minutes before sunset. So for awhile, at least, if the clouds cooperate the first moonlight and solar twilight will overlap.
The moon will reach 100 percent fullness at 5:18 a.m., or just over six hours after the arrival of the astronomical fall. At the equinoctial moment, 11:09 p.m., Jupiter will be right beside the moon.
