ASSUMING I have made no mistakes, I get a perigee at around 14:13 UT on
25 Jul 99.  This occurs basically south of Rio de Janeiro while that
region is in daylight.  Thus the IPS-1 burn will not be visible.

However, other data indicates the IPS-1 burn should occur around 2:23 UT
on 25 Jul so I do not understand the discrepancy.  I assumed the burn
would occur at perigee.
