Quiescent volcanic activity on Io in November 2010

On the first half-nights of November 29 and 30 UT, telescope time with the W.M. Keck II telescope and its Adaptive Optics (AO) was granted to us. The goal of this observation program was to search and study multiple asteroids. Since Jupiter was close to its opposition and observable at the beginning of the night, we spent a short amount of time to observe Io, innermost Galilean satellite of Jupiter, well-known for its exotic and spectacular volcanism.
