The source was in an active state during the whole monitoring campaign, showing intraday variability in 11 of 72 days. The average magnitudes in each band were B=14.398, V=13.821, R=13.255, and I=12.885. The overall variability amplitudes were {Delta}B=1^m^.834, , {Delta}V=2^m^.167, {Delta}R=2^m^.148, and {Delta}I=1^m^.912. The structure function showed that typical timescales for intraday variability were between approximately 2 and 7.5hr. The intraday variability amplitudes were from a few percent to approximately 30%. We found typical variation rates of approximately 0.05 mag/hr in both the rising and falling phases, with a minimal variability timescale of 130 minutes. A 10 day period short-term variability was observed simultaneously in the BVRI bands. The discrete correlation function suggests that there is significant correlated variability between the B- and I-band light curves. However, no significant time lags were detected. The spectral behaviors in the different variability episodes were studied, and our observations show bluer-when-brighter behavior on long, short, and intraday timescales for the blazar S5 0716+714. The variability and relevant spectral trends can be explained by the shock-in-jet scenario.2015ApJS..218...18Dhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJS/218/18CatalogResearchIsServedByTAP VizieR generic servicerelated-toJ/A+A/558/A92 : S5 0716+714 microvariability observation (Bhatta+, 2013)J/A+A/552/A98 : Optical monitoring of extragalactic sources (Taris+, 2013)J/MNRAS/435/1300 : Intranight optical variability of AGN (Goyal+, 2013)J/ApJ/768/40 : R-band & polarimetry of blazar S5 0716+71 (Larionov+, 2013)J/other/RAA/13.259 : {gamma}-ray Doppler factor for Fermi blazars (Fan+, 2013)J/ApJS/206/12 : Blazars with {gamma}-ray counterparts.
