illucidation

I’m heading out with my new camera to photograph the rise of the “super” moon over Sombrero Lighthouse.  Hubby and I  used the web page Photographer’s Ephemeris to see exactly where the moon will be coming up.  It’s a great sight for planning photo shoots.  The word ephemeris interests me tonight, perhaps even inspires me.  It is such a left-brain construct of data and tables, a surprising definition for a word so much like ephemeral which means  something brief or fleeting.  Like the creative functions of the right-brain, those elusive connections and ideas, the celestial bodies are fleeting in their positions at any given time, although predictable in general; enough so that ephemeris can be created!
