cds-question@unistra.frbl-lacertae-objectspolarimetryinfrared-photometryvisible-astronomyphotometryWe present the results of optical (R-band) photometric and polarimetric monitoring and Very Long Baseline Array imaging of the blazar S4 0954+658, along with Fermi {gamma}-ray data during a multi-waveband outburst in 2011 March-April. After a faint state with a brightness level R~17.6mag registered in the first half of 2011 January, the optical brightness of the source started to rise and reached ~14.8mag during the middle of March, showing flare-like behavior. The most spectacular case of intranight variability was observed during the night of 2011 March 9, when the blazar brightened by ~0.7mag within 7hr. During the rise of the flux, the position angle of the optical polarization rotated smoothly over more than 300{deg}. At the same time, within 1{sigma} uncertainty, a new superluminal knot appeared with an apparent speed of 19.0+/-0.3c. We have very strong evidence that this knot is associated with the multi-waveband outburst in 2011 March-April. We also analyze the multi-frequency behavior of S4 0954+658 during a number of minor outbursts from 2008 August to 2012 April. We find some evidence of connections between at least two additional superluminal ejecta and near-simultaneous optical flares.2014AJ....148...42Mhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/148/42CatalogResearchIsServedByTAP VizieR generic servicerelated-toJ/ApJS/199/31 : Fermi LAT second source catalog (2FGL) (Nolan+, 2012)J/ApJS/188/405 : Fermi-LAT first source catalog (1FGL) (Abdo+, 2010)J/ApJ/672/40 : AO 0235+164 outburst in 2006 December (Hagen-Thorn+, 2008)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AJ/148/42https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AJ/148/42http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AJ/148/42https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AJ/148/42https://vizier.iucaa.in/viz-bin/votable?-source=J/AJ/148/42http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AJ/148/42GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tap2.8492099152324443e-23 2.8492099152324443e-23InfraredOpticaldefaultJ/AJ/148/42/table1Photometry and polarimetry of S4 0954+658 during 2011 April-May outburstPol[1.7/28.9] The R band intrinsic polarization level%phys.polarization;em.opt.RfloatrecnoRecord number assigned by the VizieR team.
