11/05/2013 – Ephemeris – Latest on Comet ISON

November 4, 2013

Ephemeris for Election Day, Tuesday, November 5th.  The sun will rise at 7:25.  It’ll be up for 9 hours and 59 minutes, setting at 5:25.   The moon, 2 days past new, will set at 7:23 this evening.

I’ve seen some observed brightness measurements of Comet ISON reported to the Minor Planet Center, which is the clearing house for all things asteroid and comet related, and Comet ISON is still fainter than predicted by a factor of two.  There was one report of someone spotting it with 10X50 binoculars.  From all the reports I’ve seen the comet’s nucleus is holding together, and there is great optimism that ISON will survive its close brush with the sun on Thanksgiving day.  Some astronomers think that the comet’s nucleus spin axis is currently pointed toward the sun.  After perihelion or closest approach to the sun, the opposite pole will be exposed showing fresh material to the sun for a brighter comet in December.

Times are for the Traverse City/Interlochen area of Michigan.  They may be different for your location.
