Bob Moler's Ephemeris Blog

Ephemeris for Friday, November 29th.  The sun will rise at 7:57.  It’ll be up for 9 hours and 7 minutes, setting at 5:04.   The moon, 3 days before new, will rise at 5:02 tomorrow morning.  |  A funny thing happened to Comet ISON on its way to perihelion yesterday.  It’s nucleus disappeared.  It was dimming all morning as it approached the sun.  Most of this was visible in the SOHO LASCO C3 and C2 views.  The comet was also visible from the STEREO spacecraft currently on the other side of the sun.  These cameras are called chronographs because they hide the bright face of the sun with a disk called an occulting disk.  Just before the head of the comet was to disappear behind the disk, it disappeared all by it self, what was left was it’s tail.  However later something emerged from behind the disk where the comet was supposed to be.  I’m guessing it’s the large cloud of debris from the nucleus.

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