11/17/2016 – Ephemeris – The Leonid meteor shower will be hampered by the Moon tomorrow morning

November 17, 2016

Ephemeris for Thursday, November 17th.  The Sun will rise at 7:43.  It’ll be up for 9 hours and 29 minutes, setting at 5:12.  The Moon, 3 days past full, will rise at 8:39 this evening.

The Leonid meteor shower, which reaches peak activity today is going to be washed out by the bright Moon.  The International Meteor Organization doesn’t have anything specific on it this year.  On most years, it produces only 15 meteors an hour tops.  However about every 33 years or so all heaven breaks loose.  From the predictions I’ve seen the fun starts in 2034 and lasts a few years.  The reason for the spectacular meteor storms, as they call them, is that the responsible comet, 55P Tempel-Tuttle, has a debris clump that hasn’t fanned out much along its orbit, so we get intense meteor activity when the comet again enters the inner solar system.  It’s expected back in 2031 with its main cloud of meteoroids a couple of years later.

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