10/08/2019 – Ephemeris – Ada Lovelace Day

October 8, 2019 Comments off

Ephemeris for Ada Lovelace Day, Tuesday, October 8th. Today the Sun will be up for 11 hours and 21 minutes, setting at 7:10, and it will rise tomorrow at 7:50. The Moon, 3 days past first quarter, will set at 3:21 tomorrow morning.

Ada Lovelace Day, is an international celebration of the achievements of women in STEM, science, technology, engineering and math. Ada Augusta King, Countess of Lovelace, daughter of Lord Byron, born in 1815 is considered the world’s first computer programmer, writing a program on Jacquard loom punch cards for Charles Babbage’s Analytical Engine. Unfortunately the Analytical Engine never made it past the planning stage. The recently completed incredibly successful Cassini Mission mission had three women in top roles: Project scientist, Linda Spilker; Spacecraft Operations Team Manager, Julie Webster; Imaging Science Subsystem Principle Investigator, Carolyn Porco, plus many more. STEM fields are still male dominated but lets encourage women to enter them too.

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