A list of 681 UBVRI secondary standard stars for CCD photometry
is presented. Visual magnitude ranges from 9.7 to 19.4,
and the 
colour index varies from 1.15 to 1.97.
The stars are grouped into 11 different fields, each of them is generally
observable in a single CCD frame. The stars are located near
Landolt UBVRI equatorial standards,
accessible to telescopes in both hemispheres,
and mainly within the 5 - 8 hours range of right ascension.
Photometry,
equatorial coordinates and finding charts are provided.
Key words: methods: observational / techniques: photometric / stars: general
Based on observations made at the Centro Astronómico Hispano-Alemán and the Observatorio Astronómico Nacional in Calar Alto, Almería, Spain.
