Photoelectric BVRI photometry of several fields is presented. These data are intended to be used as "standard fields" for calibration of area detectors, specifically CCDs. The fields are located at intervals of 4 - 6 hours and are accessible from Northern Hemisphere observatories. The photometry has been converted to the "standard" system of Landolt (1983).
