If you live in North America, you won’t want to miss this celestial event. An occultation happens when one celestial body passes in front of another, thereby hiding (or occulting) it from view. In this case, on Monday evening the Full (Wolf) Moon is passing in front of Mars. Full Moon actually occurs a few hours earlier at 4:26 p.m. CST but after dark look for the rising Moon in Gemini just below the star Pollux. The occultation begins at about 7:53 p.m. CST with Mars sliding behind the Moon for viewers in the DFW area. Mars will emerge an hour later at 8:55 p.m.
