The monitoring was carried out simultaneously at three optical wavelengths with a novel photometric system. The object did not show large-amplitude internight variations during this period. Intranight variations were observed on four nights and probably on one more. Strong bluer-when-brighter chromatism was detected on both intranight and internight timescales. The intranight variation amplitude decreases in the wavelength sequence of B', R', and V'. Cross-correlation analyses revealed that the variability at the B' and V' bands leads that at the R' band by about 30 minutes on one night.2012AJ....143..108Whttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/143/108CatalogResearchIsServedByTAP VizieR generic servicerelated-toVII/258 : Quasars and Active Galactic Nuclei (13th Ed.)
