On July 3rd at 11:05:30 p.m. EDT, a 10th magnitude star in Virgo will disappear. It'll be right back. Asteroid 52 Europa will pass in front of TYC 0292-00339-1, blotting it out for only 17.9 seconds in an eclipse visible across a wide strip of North America. Measurements of the eclipse could reveal the shape of the asteroid, the seventh largest in the asteroid belt. NASA is hosting a live chat and webcast to cover the event: Tune in here.
