cds-question@unistra.frbl-lacertae-objectsinfrared-photometryvisible-astronomybroad-band-photometryWe continuously monitored the blazar S5 0716+714 in the optical g, r, and i bands from 2017 November 10 to 2019 June 6. The total number of observations is 201 nights including 26973 data points. This is a very large quasi-simultaneous multicolor sample for the blazar. The average time spans and time resolutions are 3.4hr and 2.9min per night, respectively. During the period of observations, the target source in the r band brightens from 14.16m to 12.29m together with five prominent subflares, and then becomes fainter to 14.76m, and again brightens to 12.94m with seven prominent subflares. For the long-term variations, we find a strong flatter-when-brighter (FWB) trend at a low-flux state and then a weak FWB trend at a higher-flux state. A weak FWB trend at a low-flux state and then a strong FWB trend at a higher-flux state are also reported. Most subflares show strong FWB trends, except for two flares with a weak FWB trend. The particle acceleration and cooling mechanisms together with the superposition of the different FWB slopes from the subflares likely explain the optical color behaviors. A scenario of bent jet is discussed.2020ApJS..247...49Xhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJS/247/49CatalogResearchIsServedByTAP VizieR generic servicerelated-toJ/A+A/327/61 : BV(RI)c photometry of S5 0716+714 (Ghisellini+ 1997)J/A+AS/132/83 : BVRI photometry of 7 BL Lac objects (Bai+ 1998)J/A+AS/136/455 : BVRI photometry of 3 BL Lac objects (Bai+, 1999)J/A+A/402/151 : S5 0716+714 UBVRI photometry (Raiteri+, 2003)J/A+A/450/39 : BVRI photometry of 8 red blazars (Gu+, 2006)J/AJ/133/1599 : B'V'R' photometry of S5 0716+714 (Wu+, 2007)J/AJ/135/1384 : R-band variability in 5 blazars (Gupta+, 2008)J/MNRAS/385/823 : UBVRI light curves of OJ 287 (Zheng+, 2008)J/ApJS/185/511 : Optical microvariability of S5 0716+714 (Poon+, 2009)J/ApJ/716/30 : SED of Fermi bright blazars (Abdo+, 2010)J/ApJ/722/520 : Gamma-ray light curves of Fermi blazars (Abdo+, 2010)J/ApJ/731/118 : R-band variability in blazar S5 0716+71 (Chandra+, 2011)J/ApJ/768/40 : R-band & polarimetry of S5 0716+71 (Larionov+, 2013)J/ApJS/213/26 : Optical light curves of PHL1811 and 3C273 (Fan+, 2014)J/A+A/573/A50 : Multiwavelength obs. of Mrk 501 in 2008 (Aleksic+, 2015)J/ApJS/218/18 : 2004-2012 BVRI obs. of the blazar S5 0716+714 (Dai+, 2015)J/ApJS/226/20 : X-ray, opt. & radio SEDs of Fermi blazars (Fan+, 2016)J/ApJS/222/24 : VRI LCs of BL Lac object Mrk 501 (2010-2015) (Xiong+, 2016)J/ApJ/837/45 : 2006-2012 Rc-band & 4.8GHz obs. of AO 0235+164 (Fan+, 2017)J/AJ/154/42 : BVRI photometry of S5 0716+714 in 2012 (Hong+, 2017)J/ApJS/229/21 : VRI monitoring of the QSO 3C 273 in 2005-2016 (Xiong+, 2017)J/ApJS/235/39 : Jet properties of {gamma}-ray-loud 3FGL AGNs (Chen, 2018)J/ApJ/856/80 : 6-yr optical monitoring of the FSRQ 3C 454.3 (Fan+, 2018)J/A+A/619/A45 : S5 0716+714 multi-wavelength curves (MAGIC Col.+, 2018)J/A+A/620/A185 : Long-term optical monitoring of TeV Blazars (Nilsson+, 2018)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJS/247/49https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJS/247/49http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJS/247/49https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJS/247/49https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJS/247/49http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJS/247/49GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapOpticalInfrareddefaultJ/ApJS/247/49/table2The observational datarecnoRecord number assigned by the VizieR team.
