Occultations of stars by the Moon occur routinely, but planetary lunar occultations are much rarer birds. That's why I hope you'll make the effort Tuesday morning February 18th to watch the waning crescent Moon occult the planet Mars.
Bring in winter with a bang with a beautiful, close conjunction and a rare planet-star occultation.
Now you see 'em, now you don't. Watch the Moon occult Neptune and nearby Lambda Aquarii on the same night.
