08/11/2015 – Ephemeris – Perseid meteor shower is tomorrow night

August 11, 2015

Ephemeris for Tuesday, August 11th.  The Sun rises at 6:40.  It’ll be up for 14 hours and 14 minutes, setting at 8:55.   The Moon, 3 days before new, will rise at 4:51 tomorrow morning.

The Perseid meteor shower is growing in numbers of meteors seen per hour.  The expected peak is Thursday morning about a quarter after 2.  However the peak time is only really known statistically after the event.  The point in the sky from which the meteors or shooting stars seem to come from is called the radiant and it is near the constellation of Perseus.  The meteors will appear all night from dusk to dawn.  The peak number of meteors can be up to 90 an hour.  No telescope is needed.  Just lie down on a blanket and look up.  The darker your sky the better.  One of the darkest skies around is at the Sleeping Bear Dunes National Lakeshore.  I will be leading an all night meteor shower watch at the Dune Climb Wednesday night til dawn if it’s clear.

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

Addendum

Perseid Meteors

Here are some meteors seen in the 2007 Perseid meteor shower taken by Scott Anttila. The image is centered on Cassiopeia. The radiant is low and a bit left of center in the image. The Double Cluster is seen below center and the Great Andromeda Galaxy is seen on the right above center.  Click on the image to enlarge.

Position of the Perseid radiant and stars in all-sky plots for 3 times during the night: 11 p.m., 2 a.m., & 5 a.m.

    Trying to decide between leelenau state park and sleeping bear for my sons first all night Perseid viewing. Any suggestions would be helpful as we are driving from Grand Rapids. Thanks!

      The dunes are a bit closer and afford a wider view of the sky. Both are dark sites.
