Astro-Vid of the Week: Chasing Occultations

The Moon approaches Lambda Geminorum (arrowed).

The morning was damp with dew and the hour was late. I silently hoped for batteries and gear to hang on, and dared not jitter the scope or camera, for fear of bumping off kilter the perfect alignment of optics and settings that was now producing an exquisite image of a waxing gibbous Moon with a flicker of a star just off of the approaching dark limb. WWV radio clicked away the moments in the background night. [Read more...]

AstroEvent: A Lunar Occultation.

Path of Sunday night’s lunar occultation. (Created by the author Using Google Earth & Paint).

Lunar occultations can be fun events to observe. As the moon continues its 27+ day long path around our planet, it sweeps out a 0.5 degree wide path and occasionally covers up a distant background star or planet. Such occasions can be fun events to observe, as the star winks out and later seems to pop back into existence from behind the lunar limb. Such an event occurs this Sunday, the night of March the 13-14th, as the waxing crescent Moon occults the semi-bright star Mu (µ) Geminorum.  [Read more...]
