Thank you for the comment, Mark and Alex.
Next solar eclipse will be seen at 4th Jan, 2011. AO-51 will see the
eclipse near India.
NASA Eclipse web site http://eclipse.gsfc.nasa.gov/solar.html is
interesting.

Two pictures received partially from ISS this afternoon on MMSSTV automatic
mode (Martin1), one is the second half of a picture at 1431 utc, 1 the top
half at 1433 utc, both appear to be looking out at space. The timestamp on
the first image is
