Daily encounter ephemerides for the period: Monday, 1992 Nov. 30 - Dec. 07, 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. All
known encounters are included in the list which meet the following criteria:
the true distance to each other which meet the followi

The position are given for 1950.0 and 2000.0. The elements of the orbits are
from the latest MPC or from a more recent IAUC. A list of the used elements is
given at the end of the ephemerides.

Explanations of the columns in the ephemerides:
1./2. Objekt      Names of the objects. A [P/] before the name of the object
                  means a periodic encounter with a period around the sun of
                  lower than 200 years. If the encounter have received a final
                  [Fin] designation, it's the name of the year with a roman
                  number in bracketts. If it's a provisional designation [Pro]
                  the number of the year is following by a lower letter, also
                  in bracketts. For more than 26 comets in a year, a running
                  number is in the appendix. A (number) before the name of the
                  object means a numbered asteroid with this number. A '#'
                  before the name means a one-opposition object with a not very
                  good known orbit. Nevertheless any unnumbered asteroid may be
                  several degrees wrong in his position, if the ephemerides
                  date is far from the last observations date.
Rect(1950)Decl    The rectascension in hours and time minutes and the
                  declination in degrees and arc minutes for 1950.0.
Magn              The magnitude of the encounter in magnitude steps.
Dist              The appearent distance of the objects to each other in arc
                  minutes.
RealDi            The true distance of the objects to each other in
                  astronomical units (A.U.).

These ephemerides should promote the observing of encounters.

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