cds-question@unistra.frbl-lacertae-objectsinfrared-photometryvisible-astronomyWide-band photometryccd-photometryResults of BVRI CCD photometric monitoring and fast photometry in the I band for the blazar OJ 287 in 1994-1995 are presented. The predicted outburst of the blazar had been observed, the maximum appeared in 1994 November, after that, the luminosity decreased by 1.6mag for about three months and dropped to near the level in 1994 April. Rapid variations with timescales of minutes, hours and one day were observed in our observations, with small amplitude. The amplitude of the most rapid variations (minutes) is in the range of 0.043-0.12mag . The results of the statistical analysis of the fast photometry data are as follows. In five nights out of six rapid variability appeared in the sampling interval, which ranged from 3.4 minutes to 6.5 minutes, with a rms amplitude of flux variations of 1.70%-2.3%. The rapid variability can be explained by the model of shocks within turbulent jet or of vortices and magnetic flux tubes on accretion disk.1998A&AS..129..569Jhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+AS/129/569CatalogResearchIsServedByTAP VizieR generic servicerelated-toJ/A+AS/128/315 : BVRI photometry of blazars (JiaGuibin+ 1998)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+AS/129/569https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+AS/129/569http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+AS/129/569https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+AS/129/569https://vizier.iucaa.in/viz-bin/votable?-source=J/A+AS/129/569http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+AS/129/569GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapOpticalInfrareddefaultJ/A+AS/129/569/table5Results for OJ 287recnoRecord number assigned by the VizieR team.
