Discovery of many kinds of transient astronomical phenomena (e.g., comets, novae, supernovae, etc.) are traditionally reported to the CBAT. The Bureau is responsible for assigning designations to such astronomical objects as comets, supernovae, and Galactic novae.
This webpage, designed in 2010 for activation on 2011 January 1, replaces the former "Unconfirmed Objects Page" that the CBAT ran quite successfully during the previous decade, and which was updated manually by CBAT staff members. In contrast, this new webpage is designed to be updated automatically both by astronomers worldwide who are registered (via the CBAT) to do so and (when necessary) manually by CBAT staff. This addresses a strong desire in the astronomical community for immediate posting of interesting new transient objects, to solicit confirming observations (and thus to provide a place to post confirming observations, to help prevent potentially unnecessary observations at multiple observatories).
The TOCP is designed for use with stationary, extra-solar-system objects only. Data will be postable to the TOCP directly only by registered users, who can access RSS feeds and/or receive e-mails of new postings. There is no subscription charge for access (or posting) to the TOCP. Once items are posted on the TOCP, they will be available as RSS feeds -- as has been the case since 2009 for CBETs and IAUCs. The discovery reports posted on the TOCP will be sent automatically to Skyalert.org and other VOEvent systems.
In order to post a discovery or follow-up observation to the TOCP, a user must be registered with the Central Bureau; instructions on registering and posting to this webpage are given here.

An alternate version of this webpage, in which the follow-up data are sorted by designation and then by date, is available here.. NOTE: TOCP discoveries that are published on CBETs/IAUCs or dismissed for other reasons are removed from this webpage and are listed on this separate webpage with cross-reference information.
