Operations Status</h2> The Minor Planet Center operates in two distinct modes of operation, which are described below. <h3>Processing Mode</h3> Processing is the normal mode of operation. Automated processes handle the bulk of the incoming observation batches. <h3>MPC Preparation Mode</h3> When the checking of material that is to appear in the next batch of <i>Minor Planet Circulars</i> 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. <p><hr><p> <h3>MPC Status Page</h3> A page describing any problem with the MPC (either in internal processing of observations or with the webpages or web scripts) is <a href="/iau/MPCStatus.html">available</a>. <h3>ECS Files</h3> The files available in the ECS are those associated with the 2025 JAN. 15 and 2024 NOV. 15 batches of <i>MPCs</i>. <p> <p> The last batch of mid-month <i>MPS</i> batches included in the file available in the ECS are those associated with the 20250213 batch. <!-- <p><hr><p> <h3>Dates of <i>Minor Planet Circular</i> Publication</h3> Below are listed the planned dates of <i>Minor Planet Circular</i> publication for the next year. Note that these are the UTC dates of Full Moon and availability of the files associated with these batches may occur several days before or after the stated date. Note that inclusion of a date here does not mean that a batch will actually be published: see <a href="/iau/MPCStatus.html">the status page</a> for information on skipped batches. Also note that at some point, the implementation of the new processing pipeline will render this list obsolete. <ul> <li>2017 07 09 <li>2017 08 07 <li>2017 09 06 <li>2017 10 05 <li>2017 11 04 <li>2017 12 03 <li>2018 01 02 <li>2018 01 31 <li>2018 03 02 <li>2018 03 31 <li>2018 04 30 <li>2018 05 29 <li>2018 06 28 </ul> --> <!-- Body postamble --> </div> </div> </div> <!-- footer --> <footer id="footer"> <div class="holder"> <nav class="nav"> <ul> <li><a href="/">Home</a></li> <li><a href="/about">About</a></li> <!-- Contact link changed to Jira and name changed to helpdesk.
