Spectral Chracterization of Microvariability in Quasars
Abstract
These are the preliminary results of our BVR photometric study. The quasar 1628.5+3808 is shown here only for the sake of illustration of our research. This object showed variations in the three bands. It was observed with a 1.5-meter telecope from the Observatorio Astronómico Nacional at San Pedro Mártir, México. Only non-variable field stars were taken into account to carry out the differential photometry. Problems with standard stars did not allow the calibration process.
