12/08/2014 – Ephemeris – Looking forward to the Geminid meteor shower next weekend

December 8, 2014

Ephemeris for Monday, December 8th.  The sun will rise at 8:06.  It’ll be up for 8 hours and 55 minutes, setting at 5:02.   The moon, 2 days past full, will rise at 7:28 this evening.

This upcoming weekend is the weekend of the greatest annual meteor shower of the year.  They’re the Geminids.  I confess to never having seen a Geminid.  The reason is that it’s generally too cloudy, and for me too cold.  They are now twice as active as the Perseid meteors of August with a 120 per hour peak, when the radiant point in Gemini is overhead.  The body that was discovered to produce these meteors doesn’t appear to be a comet.  It is designated as an asteroid 3200 Phaethon.  Phaethon gets extremely close to the sun at 13 million miles (21 million km) and one of the STEREO Sun monitoring satellites caught it developing a tail when close to the Sun.  Phaethon may then be the first known rock comet.  I’ll have more later this week.

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

Addendum

Geminid Orbits

Orbits of last year’s fireballs on the night of December 13-14 as recorded by NASA’s All Sky Cameras. The preponderance of fireballs (bright meteors) are Geminids. These are published daily on Spaceweather.com. Credit: NASA and Spaceweather.com
