11/17/2015 – Ephemeris – The Leonid peak is expected to be today and tonight
Ephemeris for Tuesday, November 17th. The Sun will rise at 7:42. It’ll be up for 9 hours and 30 minutes, setting at 5:12. The Moon, 2 days before first quarter, will set at 10:49 this evening.
The Leonid meteor shower is predicted to reach its peak or rather peaks today. One this afternoon is a newly computed peak, which we obviously cannot see, and another around 11 p.m. which occurs just before the radiant rises. The radiant is the point in the sky from which the meteors seem to come from, so to see any meteors that source point must be above the horizon. The Leonid meteors are the debris of Comet 55P/Tempel-Tuttle, which was discovered independently by Ernst Tempel in 1865 and Horace Tuttle 18 days later. The 55P in the name means that it was the 55th recognized periodic comet. It has a period of 33.24 years giving rise to meteor storms every 33 years or so. This isn’t one of those years.
