Daily conjunction ephemerides for the period of: Monday, 1996 Jun. 10 -
Sunday, 1996 Jun. 16. 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.

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 Apr. 19th).

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.
Thanks to Ted Bowell for his permission to use his compilation of orbital
elements
