field sketch moon july 4th 2010

Object Name : Earth, Moon and Jupiter

Object Type : Solar System

Instrument Used : Naked Eye

Location : Nashotah, WI

Date : July 4th 2010

Time : 2:45am local

Conditions : seeing 3/6, no clouds, a little dew

Media : Created a field sketch of this scene in my observing journal with pen and ink. The next day, I sketched the view with pastel pencils and black paper.

Description: The evening’s observations are drawing to a close when I notice the outline of the trees in the distance. Is that ghostly outline caused by the light of a gibbous moon? Then I realize that civil twilight is only two hours away. The light in the east is not due to the moon – but due to the sun.
