04/22/2016 – Ephemeris – Hitting on Jupiter

April 22, 2016

Ephemeris for Earth Day, Friday, April 22nd.  The Sun rises at 6:45.  It’ll be up for 13 hours and 51 minutes, setting at 8:37.   The Moon, at full today, will rise at 9:08 this evening.

The first time anyone had spotted anything hitting Jupiter was in 1994, when over 20 pieces of Comet Shoemaker-Levy 9 hit the planet over an exciting week in July.  Jupiter gets hit maybe once a year by a small asteroid making a flash or a scar visible from the Earth.  Except for Shoemaker-Levy 9, all the rest of the impacts have been discovered by amateur astronomers who create videos of Jupiter through their modest, by professional standards, telescopes.  Generally the reason for the videos is to stack the images to produce super detailed images of the planet, like my friend Scott Anttila, whose images I occasional post with these program transcripts on my blog bobmoler.wordpress.com.  Amateurs have even discovered exoplanets.

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