We find that the source fading can be well-described by a decrease in the temperature of the inner disk, which results from a combination of decreasing accretion rate and increasing inner disk radius. We model the system with a disk atmosphere model that produces the observed variations in multiband photometry (this paper) and high-resolution spectral lines (a companion paper; 2023ApJ...958..140C).2023ApJ...953...86Chttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/953/86CatalogResearchIsServedByTAP VizieR generic servicerelated-toB/vsx : AAVSO International Variable Star Index VSX (Watson+, 2006-)II/311 : WISE All-Sky Data Release (Cutri+ 2012)II/328 : AllWISE Data Release (Cutri+ 2013)II/336 : AAVSO Photometric All Sky Survey (APASS) DR9 (Henden+, 2016)I/350 : Gaia EDR3 (Gaia Collaboration, 2020)J/A+A/582/L12 : V960 Mon light curves (Hackstein+, 2015)J/ApJS/256/30 : ALMA 1.33mm images of 10 FU Orionis-type stars (Kospal+, 2021)J/A+A/649/A3 : Gaia Early Data Release 3 photometric passbands (Riello+, 2021)J/ApJ/917/80 : Opt-to-IR monitoring obs. of V1057 Cyg (Szabo+, 2021)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/953/86https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/953/86http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/953/86https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/953/86https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/953/86http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/953/86GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapOpticalInfrareddefaultJ/ApJ/953/86/tablea1*Photometry from AAVSO, Gaia, Gattini, and WISE, shown in Figure 1recnoRecord number assigned by the VizieR team.
