04/14/2016 – Ephemeris – It’s always a cloudy day on Jupiter, worse than Traverse City in winter.

April 14, 2016

Ephemeris for Thursday, April 14th.  The Sun will rise at 6:59.  It’ll be up for 13 hours and 27 minutes, setting at 8:27.   The Moon, 1 day past first quarter, will set at 3:50 tomorrow morning.

If one has a large enough telescope, possibly 100 millimeters diameter or larger Jupiter’s cloud detail can be studied.  At first appearance the clouds appear simple light and dark stripes.  They are caused by Jupiter’s rapid rotation of a bit less than 10 hours.  The dark stripes are called belts.  The darkest and broadest of these is the North Equatorial Belt.  The next darkest belt is the South Equatorial Belt, which actually disappeared for a time in 2010.  On the belt’s south side is found the Great Red Spot an anticyclone.  The white stripes are called zones.  There are more belts and zones at higher latitudes.  The Great Red Spot is kinda pink now.  In my youth in the 1950s it could be easily spotted in a small telescope and it was brick-red!

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

Addendum

Jupiter with red spot

Note how faded the Great Red Spot was.
