Subject: Re: [Phys-L] [SPAM] Re: Comet ISON
The latest issue of Sky & Telescope has diagrams of the situation for ISON in
December, and the predictions are all about seeing things just before dawn,
but their last image is for Dec. 5. The earthsky.org site shows an evening
scene for Dec. 18, which might well be correct -- it would be after the comet
has gone around the Sun, if it makes it around the Sun. What is absolutely
certain is that you can't possibly see the comet both just before sunrise and
just after sunset, on the same day.
