The dwarf planet Ceres (visual magnitude 7.0) orbiting the Sun between Mars and Jupiter passed by the barred spiral galaxy M91 in Coma Berenices last night. I also unknowningly caught the asteroid Chloris (magnitude 12.1) to its left at the same time. Choris is 124 km in diameter while Ceres is 952 km in diameter. Choris is 245 M km and Ceres is 241.2 M km distant at the moment. Above Choris is a faint 16th magnitude spiral galaxy PGC 165235. Captured with a 87% Waxing Gibbous moon nearby.
