Older Enhancements and Resolved Problems

• IMP8 ephemeris on SpaceJunk page

  2004 Apr. 22: 10:22. A user reported that the SpaceJunk page was not returning an ephemeris for IMP8. This has been fixed.

• Daily element files

  2004 Apr. 20: 11:10. A user reported that the DAILY.ELS file in the ECS was not updated. A quick check showed that the file was generated correctly and copied to the webserver, but a cronjob that was supposed to copy the file to its final destination and copy it to the mirror sites was not run. It seems that this cronjob has not been run since one of the CF's boxes was rebooted on Apr. 18. We are trying to track down the problem with the CF. The file in the ECS is now correct.
  • We also have reports of other files (e.g., neotod.dat and the mirror sites) that have not been updated. Again, this is a problem with cronjobs on the CF boxes.
  • 11:35. We have now heard back from the CF. Apparently, after the reboot on Sunday, the cron jobs did not get restored correctly. Cron was restarted around 11:00.

• NEA*.DAT files on anon-ftp server

  2004 Apr. 10: 13:00. A user reported that the NEA*.DAT files on the anon-ftp server were missing the bulk of objects with designations after 2004 DA53. A change has been made to the routine that generates these elements and the files are being regenerated.
  • 13:30. Updated files are on-line.
  • 15:55. It turns out the updated files were put into a temporary directory and the script to copy them to the proper destination was not run. This is now being run. Note that the mirror sites will not get updated until the next DOU MPEC is run.
  • 16:30. Updated files are on-line in the correct directory.

• MPChecker files

  2004 Apr. 7: 11:00. A user reported that MPChecker was not identifying objects. A check showed that the files used by MPChecker had been truncated. The affected files have been replaced. A change has been made in the routine that copies the files for use by MPChecker to prevent zero-length files being copied to the web server.

• Sky Coverage plots

  2004 Apr. 6: 11:18. A user reported that requesting fields over a range of dates would cause the fields for the earliest date to be omitted. This has been fixed.
  • 11:44. While checking out the modified Sky Coverage script, it noticed that requesting plots showing (or excluding) fields shot by a list of sites only included (or excluded) the last site specified. This has been fixed.
  • 11:55. While checking out the previous fix, it was noticed that the "just big surveys" and "just others" code had never been activated. This has been fixed.
