Abstract
We describe a method of determining the V magnitude of an asteroid using differential photometry, with the magnitudes of comparison stars derived from Carlsberg Meridian Catalogue 14 (CMC14) data. The availability of a large number of suitable CMC14 stars enables a reasonably accurate magnitude (\pm0.05 mag) to be found without having to resort to more complicated absolute or all-sky photometry. An improvement in accuracy to \pm0.03 mag is possible if an ensemble of several CMC14 stars is used. This method is expected to be less accurate for stars located within \pm10deg of the galactic equator owing to excessive interstellar reddening and stellar crowding.
