AstroEvent: When will Epsilon Aurigae Brighten?

One of the strangest variable stars is worth watching this spring.  Back in 2009, we alerted viewers to monitor the curious variable Epsilon Aurigae.

Astro-Event: Will Comet McNaught Perform?

During the month of June, keep your eye out for a pre-dawn visitor that may be the naked eye comet of the year. Comet McNaught C/2009 R1 starts the month out June 1st at about +8 magnitude near the star Beta Andromedae, and through the course of the month, skirts the constellations of Andromeda, Perseus, and Auriga. Views will get better starting June 4th, as the Moon passes Last Quarter on its way to New June 12th. The daily apparent motion of the comet will cause it to move semi-parallel to the horizon, never straying above 20° degrees elevation for mid-northern latitude observers about an hour before sunrise.
