What am I noting on tattoo Tuesday?

September 23, 2014

According to UTC (Coordinated Universal Time – or sort of Greenwich Mean Time – also Zulu Time), summer ended and autumn began at 2:29.  That would make it 22:29 EDT on Monday, September 22, where I reside. (Why UTC and not UCT or CUT?)

Approximating Earth’s orbit around the sun to be an ellipse with semimajor axis of 1 au and eccentricity of 0.0167, the distance Earth travels in one year is 940 million kilometers (584 million miles).  The average speed of the Earth around the sun is 18.5 miles/second. – ref: Wikipedia

And the tattoo:

  1. We used zulu time for important things like rendezvous and for VTCs. My favorite time was always Local Apparent Noon (LAN) which, spelled in French, is NAP. 🙂


    • Ha ha – NAP time for me, too!
