I realise this message has no Visual Satellite Observing content, but am
that it would be acceptable by the positive response that I have received.

On February 26, 1998 there is a total eclipse of the Sun. Some of you will be
travelling to Central America or the Caribbean to experience this wondrous
spectacle of nature.  Satellites too can experience eclipse, cutting down the
light that they reflect for us to be able to observe them.  An inspection of
the eclipse track diagrams indicates that once the Umbra leaves the Earth's
at around 19:09 U.T. it is possible it will envelope any satellites in the
of 30North, 10West.  A list of a few possible satellites is given below, and it
would be interesting to investigate if any of these is likely to disappear, not
in the Earth's shadow but into the Lunar shadow.
