Mark your calendar. On March 19th, a full Moon of rare size and beauty will rise in the east at sunset. It’s a super “perigee moon”—the biggest in almost 20 years.

“The last full Moon so big and close to Earth occurred in March of 1993,” says Geoff Chester of the US Naval Observatory in Washington DC. “I’d say it’s worth a look.”

The best time to look is when the Moon is near the horizon. That is when illusion mixes with reality to produce a truly stunning view.

Moon rise for Italy, Texas on Saturday, March 19 will be at 7:58am.
