Mirror of Minor Planet Center Orbit Database (MPCORB)

This is a mirror site of ftp://cfa-ftp.harvard.edu/pub/MPCORB/ maintained by the Klet' Observatory.

This directory contains the latest version of MPCORB in a
variety of formats.

  MPCORB.DAT          Uncompressed version (LF terminated)
  MPCORB.ZIP          Compressed version (LF terminated)

  MPCORBcr.DAT        Uncompressed version (CR-LF terminated)
  MPCORBcr.ZIP        Compressed version (CR-LF terminated)

The MPCORBcr files are intended primarily for users of PCs.

These files are rebuilt each night, generally between 02:00 and
03:00 EST (07:00 and 08:00 UT), except during the short period each
month when the next batch of Minor Planet Circulars are being
prepared.

Other files contain subsets of the above main file:

  NEA.DAT              NEAs (LF terminated)
  NEAcr.DAT            NEAs (CR-LF terminated)
  PHA.DAT              PHAs (LF terminated)
  PHAcr.DAT            PHAs (CR-LF terminated)
  Unusuals.DAT         Unusual objects (LF terminated)
  UnusualsCR.DAT       Unusual objects (CR-LF terminated)
  DistantObjects.DAT   Distant objects (LF terminated)
  DistantObjectsCR.DAT Distant objects (CR-LF terminated)
  DAILY.DAT            Contains the orbits newly added to MPCORB.DAT

The directory also contains the elements for the (potentially)
observable comets.

  COMET.DAT           Uncompressed version (LF terminated)
  COMETcr.DAT         Uncompressed version (CR-LF terminated)

Since the COMET*.DAT files are so small, there is no compressed version.

Also included are elements of NEAs for non-standard epochs:

  NEAtod.DAT          Elements for 0h UT today (LF terminated)
  NEAtodCR.DAT        Elements for 0h UT today (CR-LF terminated)
  NEAtom.DAT          Elements for 0h UT tomorrow (LF terminated)
  NEAtomCR.DAT        Elements for 0h UT tomorrow (CR-LF termninated)
  NEA+XX.DAT          Elements for 0h UT today + XX (LF terminated)
  NEA+XXCR.DAT        Elements for 0h UT today + XX (CR-LF) terminated)

The format of the files is described at:

http://cfa-www.harvard.edu/iau/info/OrbFormat.html

-----------------------------------------------------------------------------

Also in this directory are some files suitable for users of popular
planetarium-type software:

  SkyMap.CAT       Numbered minor planets for SkyMap
  SkyMap.ZIP       Compressed version of SkyMap.CAT

These files are updated monthly after each batch of MPCs is prepared, except
for those occasions when a mini-batch of MPCs is prepared (i.e., no new
numberings occur).
