    Here is a new picture about a pass of Phobos-Grunt over Kathmandu, Nepal.
    This is the google translation with a small corrections/explanations:
    Photographed with Eugene flying of the machine (Ph-G) over Kathmandu. There
    is clearly according to the site - the same height and
    time. Were very impressed with the speed of the machine (Ph-G) which is
    literally "whistled" over his head. I honestly had done only a couple of
    shots (with this small) soap box, (Cannon PowerShot) but was flying high -
    70 degrees.
    Bright dot Phobos-Grunt out of Capricorn, and passed through the zenith,
    where Pegasus (it is) fled to Persia.
    Photo - 10 seconds. excerpts, see the stars of Capricorn and Aquarius.
    Phobos passes straight between Alpha and Beta Capricorn.
    Tomorrow will try to make more shots, but the  (predicted) data is bad -
    low flying and we here in Kathmandu is full of buildings, though not high,
    but still, and the brightnbess of it about third magnitude.
    According to knowledgeable people, we have the first Russian amateur
    snapshot of flight apparatus (Ph-G), and the like would be the second in
    the world. That's it.
