10/08/2012 – Ephemeris – The Draconid Meteor Shower

October 8, 2012 1 comment

Ephemeris for Columbus Day, Monday, October 8th.  The sun will rise at 7:49.  It’ll be up for 11 hours and 19 minutes, setting at 7:09.   The moon, at last quarter today, will rise at 1:13 tomorrow morning.

The peak of the Draconid meteor shower is about now, (6-7 a.m. when the program airs)  as the radiant point for these meteors is low in the north.  They will be visible for the next few days  seeming to radiate from the head of the constellation Draco, near the star Vega high in the west.  These meteors are best about every 7 years, the last was last year.  So maybe we may see 15 to 20 of these meteors per hour this time.  These meteors are debris shed by Comet Giacobini-Zinner a short period comet of only 6.6 years.  These meteors are very slow moving,  about a third the velocity of the Perseid meteors of August.  Meteors are the light given off by tiny bits of material sand grain to pea size as a rule as they burn up by friction due to their great speed.

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