10/09/2018 – Ephemeris – Ada Lovelace Day

October 9, 2018

Ephemeris for Ada Lovelace Day, Tuesday, October 9th. The Sun will rise at 7:50. It’ll be up for 11 hours and 17 minutes, setting at 7:08. The Moon, 1 day past new, will set at 7:53 this evening.

Ada Lovelace Day is dedicated to Lord Byron’s daughter as the first computer programmer more than a century before the computer as we know it was invented. She worked with Charles Babbage as he designed his Analytical Engine, which would have been the world’s first truly general purpose computer, mechanical though it was.  The day is also dedicated to women in the STEM fields: Science, Technology, Engineering, and Math. Two days from now, the 11th will be the International Day of the Girl, promoting the education and possibilities of 52% of the population that aren’t male. Some of the female astronomers I follow on Twitter are astrophysicist Dr. Katherine Mack as @AstroKatie, planetary radar astronomer Alessondra Springmann as @sondy, planetary scientist Carolyn Porco, @carolynporco. These are a few, and in my field of computer programming, I celebrate the late Admiral Grace Hopper.

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