05/30/2017 – Ephemeris – Amateur astronomer detects an impact on Jupiter

May 30, 2017

Ephemeris for Tuesday, May 30th.  Today the Sun will be up for 15 hours and 17 minutes, setting at 9:19, and it will rise tomorrow at 6:00.  The Moon, 2 days before first quarter, will set at 1:44 tomorrow morning.

Last Friday several amateur astronomers photographing Jupiter with video CCDs captured a flash in the high northern latitude of Jupiter.  Part of the reason for videos is to stack the individual images to average out the turbulence of the atmosphere they were looking through.  It’s a fantastic technique.  The flash was probably due to the impact of an asteroid.  The first objects to have been seen to crash into Jupiter were the chunks of Comet Shoemaker-Levy 9 that crashed into Jupiter over a one week period in July of 1994.  Since then several flashes have been seen, all of them captured and confirmed by amateur astronomers.  Amateurs have also discovered storms on Saturn for the Cassini spacecraft to study.

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