Files Updated Ephemerides of Minor Planets (UEMP) comprise some part of
the Tables now available in the Ephemerides of Minor Planets (EMP)
published by the Institute of Applied Astronomy (IAA) on the yearly
basis. As distinct from the printed version of EMP UEMP
give corresponding information for all numbered minor planets as
of date of the last (or last but one) batch of Minor Planet Circulars
(MPC) issued by the
Minor Planet Center. Content of these Tables is
presented as a number of ASCII files downloaded into the server of
IAA in two forms, "compressed" and
"non compressed".
Elements
The files contain osculating elements of numbered minor planets
with respect to the ecliptic plane and equinox J2000 for the
standard epoch common for all minor planets. Set of data for each
planet in general corresponds to those in EMP, but some additional
information is also included.
Opposition dates
The opposition dates of the numbered minor planets within current year
are represented also in tabular form. Apart from opposition date
the apparent magnitude for the fourth ephemeris date is given for
each planet. A dash indicates that there is no opposition within current
year.
Ephemerides of minor planets, arranged in order of opposition
date, are given in the files 2016_02.eph, 2016_03.eph, and 2016_04.eph.
The files are intended to be downloaded by anonymous
user via FTP.
UEMP comprise following files.
Below the information on the files
downloaded into the IAA server (non compressed form).

458062 have two oppositions each. The planet with numbers 154244 has three
oppositions. For this planet corresponding information are given in several
lines.
The column TE of the Table contains the year of the
ephemeris volume in which the orbit was first introduced.
A dash in this column indicates that elements of corresponding
planet have never yet been published in EMP.
The following data are tabulated for each planet:
