The asteroid occultation of July 19, 2014

As told in the July 2014 Sky & Telescope, on the morning of July 19th an 8.7-magnitude star in Pisces will vanish for up to 4 seconds behind the invisibly faint asteroid 611 Valeria, as seen from a track crossing northern Mexico, Texas, the Deep South including the Atlanta area, and the Carolinas. The occultation will happen within a couple minutes of 9:10 UT in Texas and 9:12 UT in the Carolinas, where dawn will be getting under way.

Here are a map of the track, finder charts for the star, predicted times, and more details.

    It would be nice if the URL in the July magazine (p.51) brought you here rather that 404ing you. Someone forget to program the server redirect?
