There’s an occultation tomorrow (Oct 2nd, 2015) – where the Moon covers the star Aldebaran ( Rohini, as known to Indians). You can consider an occultation as an eclipse where one object in the sky covers another, as seen from the earth).
The west coast of the USA slightly misses it (or slightly gets it) depending on whee you are location. Check this link for more details.http://www.skyandtelescope.com/…/moon-hides-hyades-occults…/
I used the Neave Planetarium software to get some pictures of how it would appear in the SF bay area. I suspect the accuracy particularly when showing the Moon and the star is not perfect, but you can see through the 4 pictures how the Moon hovers over the star as time goes by.
Occulations are not as rare events, but occulations of bright stars is somewhat rare, as seen from a given place. Since there are only a few bright stars near the path that Moon takes in the sky and Aldebaran (Rohini) is the brightest star that the Moon can occult
Somehow this aspect of Rohini (that it comes very close to the Moon) made an impact on ancient Indians. So when they came up with a list of the 27 lunar mansions (“Nakshatras”), they were thought as the daughters of Daksha Brahma, and wives of the Moon. And out of these 27 wives, Rohini is said to be the most favorite of all to the Moon. It is not hard to see how this imagination come through given that the Moon occults Rohini quite regularly!
