10/14/2016 – Ephemeris – Super Moon Sunday and a weird comet

October 14, 2016

Ephemeris for Friday, October 14th. The Sun will rise at 7:57. It’ll be up for 11 hours and 1 minute, setting at 6:59. The Moon, 2 days before full, will set at 7:03 tomorrow morning.

The full moon on Sunday will be the Hunter’s Moon it will also be a super moon, though not quite as super as November’s super moon. I tend to disparage the effect because of the optical illusion that makes the Moon appear larger when near the horizon than when higher up. Besides there’s nothing out there of comparable size to compare it to. Farther out in space, the comet 29P/Schwassmann-Wachmann 1, which is weird among comets in having a nearly circular orbit between Jupiter and Saturn. It can be observed over it’s entire orbit. Normally a comet out that far is pretty much inactive. However every once in a while it produces an outburst, brightening and expelling a cloud of gas and dust. This can occur up to 7 times a year.

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


This month’s super Moon will appear to be 33.4 minutes of arc in diameter when it will rise Sunday night at 7:40 p.m. in the Traverse City/Interlochen area.  It will be 222,393 miles (357,906 km) away.  November’s super Moon will rise November 14 at 5:53 p.m. and appear to be 33.6 minutes of arc in diameter.  Note that half a degree is 30 minutes of arc.  Last April 2nd’s mini Moon was 29.4 seconds of arc in diameter when it rose.  It was 252,262 miles (405,977 km) away.  This full Moon will appear 13.6% larger than last April’s  full Moon.
