CCD photometry of asteroids 970 Primula and 1631 Kopff obtained remotely at Tenagra Observatories during October and November 2003 is reported. A synodic rotation period of 2.777±0.001 hours is determined from four nights of observations for Primula. The resulting rotation period for Kopff is 6.683±0.001 hours from five nights of observations. Both observed lightcurves were nearly symmtrical with amplitudes of 0.18±0.02 magnitudes for Primula and 0.41±0.04 for Kopff.
