Daily encounter ephemerides for the period: Monday, 1992 Nov. 23 - 30, 0 h UT
(Universal Time). The encounters are sorted by Right Ascension. The close
encounters in space are also listed, if they happen close to the sun. Such
encounters may disturb the orbits after some time. Due to e-mail problems the
posting of the five different ephemerides has to be made on three days. Only
every fifth issue of these different ephemerides detailed explanations are
given alternately!

These ephemerides should promote the observing of encounters.

These ephemerides were computed by a program of Jost Jahn with an Atari ST
computer.
