10/16/2015 – Ephemeris – The topic this Saturday will be comets (Updated)

October 16, 2015

Ephemeris for Friday, October 16th.  The Sun will rise at 7:59.  It’ll be up for 10 hours and 57 minutes, setting at 6:56.   The Moon, half way from new to first quarter, will set at 9:20 this evening.

Tomorrow I have a treat for youngsters of all ages.  From 10 a.m. to noon ( Update:  noon to 2 p.m.)  I’ll be talking about and helping to make comets at the Betsie Valley District Library in Thompsonville.  First we’ll explore comets as seen in our skies then travel along with the Rosetta space mission to get up close to Comet 67P/Churyumov–Gerasimenko to see what it’s made of and what happens when it comes close to the Sun.  Then we’ll make our own comet nucleus using many of the ingredients that are found in actual comets, though we’ll leave out all the poisonous ones, and we’ll see if it survives this close to the Sun.  If you want to help make a comet, bring your winter gloves.  I do have extras, but yours will probably work better.

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