Seeing was worse this morning than yesterday, which was worse than the
night before, when it was only mediocre. Despite this, Deimos was
visible at 650x in my 10-inch. Although Phobos is a magnitude brighter,
it is also much closer to the planet. The light from Mars kept Phobos
hidden from view, even when Mars was hidden beind the high-tech,
Aluminium foil occulting bar.
The article about viewing Martian moons in the August issue of S&T is a
great help. For a real-time view, Starry Night Pro does a good job
showing the present central meridian and moon orientation when it's not
busy locking up my computer. Also, Mars Viewer
(http://ringmaster.arc.nasa.gov/tools/viewer2_mar.html) shows the
orientation of the moons at any time.
