Older Enhancements and Resolved Problems

• No ephemeris returned

  2003 June 30: 14:49. A user reported that no ephemeris was returned when an small-interval ephemeris was requested for a MBA.
  • Updated code was put on-line at 16:50.

• Unexpected service outage

  2003 June 28: 13:31. The webserver removed itself from the cluster and did not reboot cleanly.
  • Normal service was restored at 15:20.

• MPES Documentation PDF file

  2003 June 18: 17:10. The on-line PDF documentation has been replaced with a much smaller file (the size has decreased from 8.5 MB to under 0.5 MB). This shrink was accomplished by converting the `deep sprite' images used in the document to `256-colour' images (RISC OS users will understand this!).

• Residual Blocks for Unperturbed Orbits

  2003 June 17: 17:00. Again, not a problem but an enhancement. Starting with last night's DOU MPEC, residual blocks for new 1-opposition unperturbed orbits will be available via the MPES.
  • June 17: 17:20. The available residual blocks have been back-extended to the June 14 DOU MPEC.
  • June 17: 17:23. The on-line documentation has been updated to reflect this change.

• Sometimes Incorrect Comet Magnitudes

  2003 June 17: 13:00. Under certain circumstances incorrect predicted magnitudes would be generated for comets. This has been fixed.

• Incorrect Vaisala elements

  2003 June 17: 12:00. There was confusion between the Vaisala elements of recently-observable and not-recently observed minor planets. E.g, you requested 2003 GV₃₇ and you got 1992 SK₂₁ (!). This has been fixed.

• Designations in the new MPES

  2003 June 13: 17:50. It has been reported that the provisional to permanent designation converter is not working for the objects newly numbered in the June MPCs. The necessary data *are* present in the relevant files. We are investigating...
  • June 13: 18:10. The problem wasn't with the designation conversion routines, but rather with the file of numbered minor planets elements. The file used by the MPES was generated by the old MPES routines and these have been disabled. The relevant bits of the old processing have been reactivated for the future and the file of numbered elements is being rebuilt now.
  • Corrected files were on-line by 18:35.
