Three days after getting shots of Deimos traversing the Sun there is another set of Sub-Frame EDR shots of the sun with something much larger just clipping the edge. I'm assuming that it's Phobos. Still no Full Frame shots of either event. Perhaps they are just waiting to get a Full Monty from Phobos before they do a show-and-tell.

Thanks burmese!

It is interesting to note that the two images with Phobos are only ten seconds apart!

Do you have a pointer to something that predicts these eclipses? I don't know how to tell when they will be happening.

Don't have any idea as to any software or web page that shows eclipse/orbital info on either of the Marsmoons. Perhaps if you asked the people who make software that predicts lunar eclipses theymight be able to point you in the right direction. Obviously NASA tracks this stuff closely but I doubt they have it posted anywhere.

I think they said that it takes Phobos about 32 seconds to move across the full width of the Sun.

SpaceFlightNow has a full article about the moons and their passing in front of the Sun. Also mentions that Venus will pass between the Earth and the Sun later this year for the 1st time since 1882

Starry Night Pro might simulate a Martian solar eclipse... www.starrynight.com
