For roughly 60 minutes in the morning on Tuesday, Feb. 18, astronomers and skywatchers alike will be able to watch Mars disappear behind the Moon, an unusual event.
About 15 seconds should elapse for the moon to fully cover (or uncover) the tiny disk of Mars.The two planets need to be high enough in the sky to be easily seen, and if it's after sunrise where you are, a telescope is required. 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. Those residing within the Mountain Time Zone have the most optimal viewing opportunity. People located in the Pacific Time Zone will be able to catch the end of the ocultation.
Under reasonably dark skies, this event can be watched over western locations with the naked eye or binoculars, although a telescope will provide the best views. For New England, upstate New York, Toronto and Montreal, the greater New York City area and New Jersey, Middle Atlantic Coast, Piedmont and Southeast Coast including Florida, the entire occultation will be a daytime affair.
