Comet C/2004 Q2 Machholz and Pleiades
Encounter of Machholz comet with Pleiades was a fascinating event. At midnight January 7th/8th the
narrow ion tail was passing directly through the Pleiades open cluster. The unusual viewing geometry
caused that the angle between the blue ion tail and white dust tail (directed downwards) was about
115°.
