Transit of Phobos from Mars

Transit of Phobos from Mars
(A reminder that solar eclipses on Mars accur houndrets of times in the year, and that would be a good and interesting thing to add to MCO)



Quote
On Mars, only partial solar eclipses (transits) are possible, because neither of its moons is large enough, at their respective orbital radii, to cover the Sun's disc as seen from the surface of the planet. Eclipses of the moons by Mars are not only possible, but commonplace, with hundreds occurring each Earth year. There are also rare occasions when Deimos is eclipsed by Phobos.[23] Martian eclipses have been photographed from both the surface of Mars and from orbit.

Viewed from orbit, the penumbral shadow of Phobos can be seen to move rapidly over the Martian surface. This shadow on the Martian surface has been photographed on many occasions by Mars Global Surveyor.

I'm pretty sure I saw at least one of them when I was playing yesterday and looked up at the sky.
