(meteorobs) [Fw: Comet ISON Meteor Shower]

[Pat Branch]

By my calculations for pieces to be hitting us now would require an ejection velocity of about 11km/sec a little too large to be likely.

The point of closest passage occurs on Jan 15, but a couple of experts I talk to seem to be predicting more on the 16th or 17th for some reason. The most likely time span is Jan 12-18 and the meteors should appear to come from Draco.

I will be keeping an eye out for a rise in rates at that time.

I’m also interested in what becomes of the massive particle dispersion that comes from it’s disruption, though the outbound trajectory takes it fairly far from Earth. Still some of the meteoroids would have been kicked backwards from the trajectory and thus should hang out in the inner solar system. Maybe someone will write up a paper about that.

From poking around there is an overlap of discussion of ISON as a sun grazer and as an Oort cloud object. People talk about meteors in either context.
