MPC Operations StatusThe Minor Planet Center operates in two distinct modes of operation, which are described below.
Processing ModeProcessing is the normal mode of operation. Automated processes handle the bulk of the incoming observation batches.
MPC Preparation ModeWhen the checking of material that is to appear in the next batch of Minor Planet Circulars begins, the MPC switches into preparation mode. The primary difference between preparation and processing modes is that new observatory codes are not attended to in preparation mode. Most automated procedures handle observations as in processing mode.
MPC Status PageA page describing any problem with the MPC (either in internal processing of observations or with the webpages or web scripts) is available.
ECS FilesThe files available in the ECS are those associated with the 2023 SEP. 12 and 2023 SEP. 12 batches of MPCs.
The last batch of mid-month MPS batches included in the file available in the ECS are those associated with the 20231115 batch.
