Comet ISON: Unique Meteor Shower Mid-January 2014

This November, the second bright comet of 2013, Comet C/2012 S1 (ISON), is predicted to be at its brightest.

Comets often produce plumes of dust. If these dust plumes intersect the orbit of the Earth, we observe meteor showers. Paul Wiegert of the University of Western Ontario has been modeling the dust plumes and offered the following prediction...

"For several days around January 12, 2014, Earth will pass through a stream of fine-grained debris from Comet ISON. The resulting shower could have some interesting properties."

While the comet is expected to brightest in late November, the Earth will not intersect the dust plume until a couple months later. And while this could be the brightest comet we've seen in many years, comets are notoriously unpredictable. However it is worth looking for Comet C/2012 S1 (ISON) and the associated meteor shower. Note late November is merely when the comet is brightest, it should be visible before and after that time. See the following for more details...
