Here are links to the MPC/CBAT (Extended) Computer Services on the WWW. The link to the downloadable versions of the various journals is at the bottom of the list.- Page listing known problems with pages/scripts on this site and their resolution
- MPC Orbit (MPCORB) Database
The MPC's database of orbital elements of minor planets is
available for anon-ftp downloading from
ftp://cfa-ftp.harvard.edu/pub/MPCORB/.
It is updated daily as new orbits are computed at the MPC. You should
examine the file ReadMe.txt
for details on which version of MPCORB you should download.
- Mirror sites of the MPCORB datafiles are available.
- Details on the different access modes for the Web Computer Services.
- Web Computer Service
- If prompted for a username and password when trying to access one of the services listed below, enter the CS/ECS username and CS password.
- Circulars, ephemerides, orbital elements and services for observers are available here.
- Circulars are now accessible
- IAUMail: Resend e-mail circulars that fail to arrive.
- Web Extended Computer Service
- If prompted for a username and password when trying to access one of the services listed below, enter the CS/ECS username and ECS password.
- NOTE: These services will be unavailable while the files are being updated with each monthly batch of MPCs. When mid-month MPS batches are being filed, access will also be disabled.
- MPCAT The files are current through the batch of Minor Planet Circulars dated 2010 JAN. 30 .
- MPCAT-OBS
The files are current through the batch of
Minor Planet Circulars dated
2010 JAN. 30
.
- There is now the option to download observation files that are complete through the last mid-month MPS batch.
- MPCUPDATE. The files available currently are those for the batches of Minor Planet Circulars dated 2010 JAN. 30 and 2009 DEC. 31 .
- MPCArchive: allows access to the complete sets of PDF versions of the back issues of the MPCs, MPSs and MPOs.
- MPCOBS. Extract observations of specific minor planets, comets and natural satellites.
- The latest batch of new names and citations is available prior to the release of the main datafiles associated with each batch of MPCs.
- New batches are put on-line when they are completed. Normally, new batches will be on-line on or before the date of full moon, but if they are delayed (generally because of a later than normal start date), please do not send us messages asking where they are!
- Downloadable PostScript and PDF versions
of recent MPC, MPS and MPO issues
- In order to access these PS/PDF files you must have a subscription to the Minor Planet Circulars (MPCs) (a subscription to the Minor Planet Electronic Circulars (MPECs) is not sufficient).
- In light of the severe truncation in the distribution of printed
versions of the MPCs, all MPC subscribers may now
download these files.
- If you are an ECS subscriber, use your CS id and ECS password to access these files.
- If you are a CS subscriber, use your CS id and CS password to access these files.
- If you subscribe to neither the CS nor ECS, you should make an e-mail request for your access details to iausubs@cfa.harvard.edu.
- If you have more than one account, make sure you use the access details from the account with the MPC subscription.
- This service allows access to the two most recent issues only.
- You are asked to notify us via e-mail (to iausubs@cfa.harvard.edu) if you wish to no longer receive any printed MPCs via snail-mail.
telnetaccess to the computer services has been retired.
Please note that the WebCS username and password are case sensitive! If
you are a subscriber and you have problems please send e-mail to
iausubs@cfa.harvard.edu, stating your account number.
