The maximum variabilities are {Delta}m_V|max_=1.74+/-0.02mag in the V band, {Delta}m_R|max_=0.97+/-0.02mag in the R band, and {Delta}m_I/max_=1.15+/-0.03mag in the I band. During the monitoring period, we obtain intraday variabilities on 2009 September 2 (JD2455077) and 2009 September 3 (JD2455078). On 2009 September 2, the intraday variabilities are {Delta}m_V_=0.36+/-0.08mag within 1.56hr, {Delta}m_R_=0.21+/-0.04mag within 23minutes, and {Delta}m_I_=0.53+/-0.03mag within 45minutes. On 2009 September 3, the intraday variabilities are {Delta}m_V_=0.40+/-0.10mag within 27minutes, {Delta}m_R_=0.48+/-0.04mag within 3.24hr, and {Delta}m_I_=0.68+/-0.06mag within 3.72hr. The two intraday variabilities occur in 24hr, which may occur in the same variable phase. Other results show that (1) no quasi-periodicity is found in the long-term light curve and (2) the correlations between the brightness and the spectrum show obvious anti-correlation, {alpha}=-(0.18+/-0.02)F_V_+(2.33+/-0.12), with the correlation coefficient r=-0.74 and the chance probability p<0.01%.2015AJ....150...67Yhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/150/67CatalogResearchIsServedByTAP VizieR generic servicerelated-toJ/ApJS/213/26 : Optical light curves of PHL1811 and 3C273 (Fan+, 2014)J/ApJS/185/511 : Optical microwariability of S5 0716+714 (Poon+, 2009)J/MNRAS/392/1181 : BV(RI)c photometry of 3C 273 (Dai+, 2009)J/AJ/135/1384 : R-band variability in 5 blazars (Gupta+, 2008)J/A+A/450/39 : BVRI photometry of 8 red blazars (Gu+, 2006)J/A+A/406/L9 : TeV Gamma-Rays from 1ES 1959+650 (Aharonian+, 2003)J/A+AS/144/481 : BVRI photometry of 5 X-ray selected BL Lacs (Villata+, 2000)J/ApJ/522/846 : Optical monitoring of GeV loud blazars (Xie+, 1999)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AJ/150/67https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AJ/150/67http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AJ/150/67https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AJ/150/67https://vizier.iucaa.in/viz-bin/votable?-source=J/AJ/150/67http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AJ/150/67GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapInfraredOpticaldefaultJ/AJ/150/67/table2The VRI observations of 1ES 1959+650recnoRecord number assigned by the VizieR team.
