With the appearing of this list orbital elements from the file astorb.dat
by
E. Bowell are used.

Author : a.doppler@uriela.in-berlin.de (Andreas Doppler)

Daily conjunction ephemerides for the period of: Monday, 1996 Mar. 18 -
Sunday, 1996 Mar. 24. The conjunctions are sorted by time (UT). All known
asteroids of the file astorb.dat by E. Bowell and objects of the NGC 2000.0
are included in the list which meets the following criteria: The minimum
elongation to the sun has to exceed 30 degrees, the maximum elongation to
the
NGC/IC Object is 10 arcmin and the limiting magnitude of the asteroid is
brighter or equal than 14.0 mag. The Ephemerides were calculated with a
step
of 5 min. Coordinates are for J2000.0 and FK5. Every fifth issue detailed
explanations are given at the end of the ephemerides.

If the asteroid is not numbered, alternately the designation is given.
'JDate'
is the Julian Date yymmdd for the anomaly M in degrees. 'Halfa' is the
great
half axis a in astronomical units. 'Eccen e' is the eccentricity of the
orbit. 'Perihel', 'Node' and 'Inclin.' are the 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). The Source of the elements is the file
ASTORB.DAT
published by E. Bowell. These orbital element list is only for an overview,
which orbit I used. For all objects the accuracy of the published original
elements are some digits better than given here.

Explanations of the columns in the ephemerides:

J2000.0.
Magn              The magnitude of the NGC/IC Object in magnitude steps.
Size              The size of the NGC/IC Object in arc minutes.
Dist              The distance of the asteroid to the NGC/IC Object in arc
                  minutes.
Pos               The asteroid's position angle to the NGC/IC Object (from
                  north over east, south and west back to north, 0..360
                  degrees).

The ephemerides should promote the observing of conjunctions.

The ephemerides were computed with a program by Andreas Doppler with an
Apple
Performa 630 computer (Version of 1996 Mar. 5th).

Please let me know if you observed a conjunction (or not).
You can reach me at a.doppler@uriela.in-berlin.de.

Because of the reason that software and/or datas may be incorrect, I cannot
guarantee the correctness of the ephemerides above.

Thanks to Arturo R. Montesinos (aramirez@servcoiae.recol.es) for bug
reports.
