Daily asteroid ephemerides for the period: Monday, 1993 Jan. 25 - Feb. 01, 0 h
UT (Universal Time). Due to e-mail problems the posting of the five different
ephemerides has to be made on three days. All known asteroids are included in
the list which meet the following criteria: the minimum elongation to the sun
has to exceeds 30 degrees. and the limiting magnitude of the asteroid is
brighter than 11.0 mag.

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.

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.


Explanations of the columns in the ephemerides:
Name of object    The name of the object. A (number) before the name of the
                  object means a numbered asteroid with this number.
Rect(1950)Decl    The rectascension in hours and time minutes and the
                  declination in degrees and arc minutes for 1950.0.
Rect(2000)Decl    The rectascension in hours and time minutes and the
                  declination in degrees and arc minutes for 2000.0.
r                 The distance of the asteroid to the sun in A.U.
d                 The distance of the asteroid to the earth in A.U.
Elo               The elongation of the asteroid to the sun in degrees.
Pha               The phase angle of the asteroid to the sun in degrees.
Magn              The magnitude of the asteroid in magnitude steps.
MotioPos          The motion of the asteroid in arc seconds/hour and the
                  position angle of the motion (from north, over east, south
                  and west back to north, 0..360 degrees).

These ephemerides should promote the observing of asteroids.

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