11/16/2015 – Ephemeris – The Leonid meteors are expected to reach their peak tomorrow

November 16, 2015

Ephemeris for Monday, November 16th.  The Sun will rise at 7:40.  It’ll be up for 9 hours and 33 minutes, setting at 5:13.   The Moon, 3 days before first quarter, will set at 9:45 this evening.

Tomorrow night is the expected peak of the Leonid meteor shower.  The expected peak will be at 11 p.m. (4 hr UT November 18). Problem is that the radiant won’t rise until just after midnight for northern Michigan.  For the best visible numbers the peak of the meteor shower should coincide with the time the radiant is highest in the sky.  For the Leonids, that’s when morning twilight starts.  There’s another possible peak for those in Asia at 21 hr UT November 17.  It’s afternoon for us.  The Leonids generally produce their meteor storms of thousands of meteors an hour about every 33 years, when the comet is back near the Earth and the Sun.  That next time would be around the year 2031 give or take a year.  I personally missed the meteor storm of 1966 by a couple of hours.  I missed the one in the late 90s by more than that. The next  around 2031 may be a bridge too far for me.

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