The moon eclipsed Mars today... 2/18
Between late Monday and early Tuesday, sky watchers in much of North America might be able to catch the waning crescent moon transit in front of Mars, depending on their region.
“A lunar occultation involving a planet is a rare event,” astronomy blogger Dave Samuhel reports for AccuWeather. “There are only a few per decade as seen from any given spot on the globe.”
The moon will 'eclipse' Mars before dawn Tuesday! Here's how to see it.
Parts of the western and central U.S. and Canada will be able to view both the disappearance and reappearance of the Red Planet in a dark or twilight sky. However, from western Canada, the Pacific Northwest and northern portions of California and Nevada, only the end of the occultation will be seen, since Mars will already be behind the moon when it rises around 3:30 a.m. local time. On the other hand, across the Eastern U.S., the planet will both disappear and emerge after sunup.
