Abstract
A list of 681 UBVRI secondary standard stars for CCD photometry is presented. Visual magnitude ranges from 9.7 to 19.4, and the B V colour index varies from 1.15 to 1.97. The stars are grouped into 11 dierent elds, each of them is generally observable in a sin- gle CCD frame. The stars are located near Landolt UBVRI equatorial standards, accessible to tele- scopes in both hemispheres, and mainly within the 5 8 hours range of right ascension. Photometry, equatorial coordinates and nding charts are provided.
