12/29/2014 – Ephemeris – More events from 2014

December 29, 2014

Ephemeris for Monday, December 29th.  The sun will rise at 8:19.  It’ll be up for 8 hours and 51 minutes, setting at 5:10.   The moon, 1 day past first quarter, will set at 2:32 tomorrow morning.

2014 has been a year of eclipses for northern Michigan.  A total lunar eclipse on the morning of April 15th, another on the morning of October 8th.  Plus we had a partial solar eclipse at sunset on October 23rd.  All of them were hampered by clouds, for this observer.  One of the cool events of this year was the close approach of Comet Siding Spring with Mars.  The five functioning orbiters and two rovers were not able to get any spectacular pictures of the comet, but there was one heck of a meteor shower on Mars when the planet was closest to the comet’s path.  None of the satellites could see it because they were hiding behind the planet at the time.  But later the martian atmosphere was filled with the chemical signatures of the meteors.

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