Abstract

The asteroid (147857) 2005 UW381 will pass over the supergiant star Betelgeuse on January 2nd 2012. The event is visible on a limited geographical region, and the magnitude drop is only 0.01 magnitudes for a maximum duration of 3.6 seconds. The opportunity to measure this phenomenon can be interesting for dealing with extrasolar planetary transits.
