02/14/2017 – Ephemeris – Is the Moon waxing or waning?

February 14, 2017

Ephemeris for St Valentine’s Day, Tuesday, February 14th.  The Sun will rise at 7:43.  It’ll be up for 10 hours and 26 minutes, setting at 6:10.  The Moon, half way from full to last quarter, will rise at 10:18 this evening.

This morning the waning gibbous moon will be a way to the right of the bright planet Jupiter which is in the southwest at 7 a.m. Tomorrow morning the Moon will appear above and right of Jupiter.  My granddaughter is taking earth science in school now and is confused about when the Moon is waxing or waning.  If it’s waxing it is getting fuller each night. If waning the Moon’s phase is getting thinner each night.  But I told her that if you can see the Moon in the evening it’s waxing, and if you can see the Moon in the morning it’s waning.  It works except around full Moon where you’d need a calendar for the full moon date or if it rises before or after sunset.

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