After the outburst by nearly 2.9mag in r around September 2014 the brightness gently fades until April 2015 by nearly 1mag in U and 0.5mag in z. Thereafter the brightness at {lambda}>5000{AA} was constant until June 2015 while the shortest wavelengths (U,B) indicate a new rise, similar to that seen for the FUor V2493 Cyg (HBC722). Our near-infrared (NIR) monitoring between December 2014 and April 2015 shows a smaller outburst amplitude (~2mag) and a smaller (0.2-0.3mag) post-outburst brightness decline. Optical and NIR color-magnitude diagrams indicate that the brightness decline is caused by growing extinction. The post-outburst light curves are modulated by an oscillating color-neutral pattern with a period of about 17 days and an amplitude declining from ~0.08mag in October 2014 to ~0.04mag in May 2015. The properties of the oscillating pattern lead us to suggest the presence of a close binary with eccentric orbit.2015A&A...582L..12Hhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/582/L12CatalogResearchIsServedByTAP VizieR generic servicerelated-toJ/A+AS/124/33 : BN Ori UBV photometry + equivalent width (Shevchenko+ 1997)J/A+A/556/A60 : BVRI observations of the FUor star V582 Aur (Semkov+, 2013)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/582/L12https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/582/L12http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/582/L12https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/582/L12https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/582/L12http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/582/L12GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapOpticalInfrareddefaultJ/A+A/582/L12/lc_dataLight curves of V960 MonrecnoRecord number assigned by the VizieR team.
