3.1416 – 03/14/2016 – Ephemeris – When Jupiter hits your eye like a big pizza Pi

March 14, 2016

Ephemeris for Pi Day 3/14, Monday, March 14th.  The Sun will rise at 7:56.  It’ll be up for 11 hours and 52 minutes, setting at 7:48.   The Moon, 1 day before first quarter, will set at 2:39 tomorrow morning.

We turn again to the giant planet Jupiter which is shining brightly in  the southeastern part of the sky in the early evening.  The first thing one notices in a small telescope are it’s four moons, generally in a straight line, which move back and forth each night.  Notice their plane.  It’s the same direction as the cloud bands are aligned.   Jupiter has a very small axial tilt, and its large satellites orbit pretty much over Jupiter’s equator.  Our Moon doesn’t behave that way, but that’s another story.  Jupiter rotates on its axis in a bit less than 10 hours, which whips its clouds into alternating bands of reddish-brown and cream color.  Also the rotation rate of these clouds lessens with increasing latitude.

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

Answer to Friday’s Moon phase poser

Of the two representations of the Moon’s terminator last Friday, the Virtual Moon Atlas was the correct representation.
