An Ephemeris of the Martian Moons.

This is a quick posting of the best apparitions of the moon of Mars, Deimos and Phobos, as promised in the Mars opposition post. The tables run for a week after opposition, and are accurate to about 10 minutes or so. I hand crafted these in Starry Night after I found a lack of info about the web for this data. Obivously, we here at Astroguyz see a definite gap that those looking to spot these ellusive beasties are in need of. With Mars at opposition, the closest Full Moon of the year, and two back to back launches, its going to be a busy last week of January…. we’ll have a larger post out on tips to spy the Martian moons this weekend!
