Iridium max elevation

Sun, 31 Aug 1997 11:02:02 -0500

Based on Ron's note to Craig, I do not think the maximum elevation of
around 56 degrees during my recent August observations of the latest
Iridiums will be of much help. The flaring occurred at a much lower
elevation. Hence the geometry is somewhat unique. As long as the passes
occur at the same geometry for a few days in a row, it is likely that
once first detected, an alert can be put out for the next day in the
same geographic region. For SEESATers outside of that TBD region, the
geometry will likely be very different such that no flaring will be
visible. This has been confirmed by reports on the net up to now.
