Daily encounter ephemerides for the period: Monday, 1993 Jan. 18 - 25, 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!

The name is the same as in the ephemerides, but a littlebit shorter. 'JDate' is
the Julian Date yymmdd for the anomaly M in degrees. 'Halfax.' is the great
half axis a in astronomical units. 'Eccentr e' is the eccentricity of the
orbit. 'Perihel', 'Node' and 'Inclin.' are these three orbit angles in degrees.
H is the magnitude of the object in 1 A.U. from the sun and the earth, G is the
factor in the calculation of the objects brightness, which is too complicate to
list here (see textbooks). These orbital element list is only for an overview,
which orbit I used. For well-known objects the accuracy of the published
original elements may be some digits better than given here. Please note, that
for conjunctions and encounters sometimes also cometary orbital elements before
the minor planets orbital elements are given. Those cometary elements are given
in the cometary and not in asteroidal element format. Especially note, that not
q, but a is given!

These ephemerides should promote the observing of encounters.

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