plotted moon elongations

woo hoo! At first I didn't think there was a tool specifically for Mars. But a bit of creative searching, and I found it! Like what I've done with the outer gas giants, I used the Tracker Tool, version 2.6, PDS Ring-Moon Systems Node (tool link) from SETI. (It is not listed in the web interface menu...)

plot of Martian moons for 4 weeks

Wow. They are zippy! Deimos appears to be just over 1 day. Phobos looks to be 2 or 3 times a day!

Slowed it down a bit...

plot of Martian moons for 2 days

There. That'll be handy for a given evening...

Oh boy. Phobos is gonna be tough, never more than 1 planet diameter away!
