07/28/2014 – Ephemeris – One meteor shower is at peak and another is ramping up.

July 28, 2014 Comments off

Ephemeris for Monday, July 28th.  The sun rises at 6:24.  It’ll be up for 14 hours and 48 minutes, setting at 9:12.   The moon, 2 days past new, will set at 9:46 this evening.

We have a couple of meteor showers of note coming up.  The first is the Southern Delta Aquarids which will peak on the 30th.  The radiant point for these meteors will rise around midnight in the southeast.  Their numbers and their brightness are not very great.  The Perseid meteor shower will have the misfortune to coincide with the full moon on August 12th and 13th, drowning out all but the brightest meteors.  However the Perseids have a long run up to their peak, so their numbers will grow after the moon sets until the moon sets in morning twilight.  The Perseid radiant is circumpolar for Northern Michigan, meaning it never sets, so some Perseid meteors can always be seen at night.  Their radiant will be in the northeastern sky in the evening.

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