cds-question@unistra.frgalaxiesstandard-starsinfrared-photometryvisible-astronomyphotometryWe present new, very late time optical photometry and spectroscopy of the interesting Type II-P supernova SN 2002hh, in NGC 6946. Gemini/GMOS-N has been used to acquire visible spectra at six epochs between 2004 August and 2006 July, following the evolution of the SN from age 661 to 1358-days. Few optical spectra of Type II supernovae with ages greater than 1yr exist. In addition, g', r', and i' images were acquired at all six epochs. The spectral and photometric evolution of SN 2002hh has been very unusual. Measures of the brightness of this SN, both in the R and I bands, as well as in the Halpha emission flux, show no significant fading over an interval of nearly 2-years.2007ApJ...669..525Whttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/669/525CatalogResearchIsServedByTAP VizieR generic servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/669/525https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/669/525http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/669/525https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/669/525https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/669/525http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/669/525GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapOpticalInfrareddefaultJ/ApJ/669/525/table2*Tertiary VRI photometric standards for NGC 6946recnoRecord number assigned by the VizieR team.
