"UCAC-3 catalogue: UCAC-3 is a continuation of the UCAC-2 project. It provides high-quality astrometry and decent photometry for 100 million stars, covering the entire sky. It is available on a double-sided DVD, and will probably be the standard for people doing asteroid photometry. It essentially renders GSC in all forms, including GSC-ACT, completely obsolete.

UCAC-3 is available from the US Naval Observatory on a double-sided DVD at no cost. Click here for more info on UCAC-3, including on how to get the data. If USNO runs out of DVDs, which seems quite likely, check this page; I'll probably attempt to arrange a system wherein the disks can be passed around and copied.

I've posted C/C++ source code for accessing UCAC-3 data."
