The fields chosen for the first observations of the cosmic microwave background with the Very Small Array have been surveyed with the Ryle Telescope at 15 GHz. We have covered three regions around RA 00 h 20 m Dec. +30° , RA 09 h 40 m Dec. +32° and RA 15 h 40 m Dec. +43° (J2000.0) , an area of 520 deg 2 . There are 465 sources above the current completeness limit of ≈25 mJy , although a total of ≈760 sources have been detected, some as faint as 10 mJy. This paper describes our techniques for observation and data analysis; it also includes source counts and some discussion of spectra and variability. Preliminary source lists are presented.
