cds-question@unistra.frsupernovaeinfrared-photometryvisible-astronomybroad-band-photometryWe present high-cadence UV, optical, and near-infrared data on the luminous Type II-P supernova SN2017gmr from hours after discovery through the first 180 days. SN 2017gmr does not show signs of narrow, high-ionization emission lines in the early optical spectra, yet the optical light-curve evolution suggests that an extra energy source from circumstellar medium (CSM) interaction must be present for at least 2 days after explosion. Modeling of the early light curve indicates a ~500R{sun} progenitor radius, consistent with a rather compact red supergiant, and late-time luminosities indicate that up to 0.130{+/-}0.026M{sun} of 56Ni are present, if the light curve is solely powered by radioactive decay, although the 56Ni mass may be lower if CSM interaction contributes to the post-plateau luminosity. Prominent multipeaked emission lines of H{alpha} and [O^I^] emerge after day 154, as a result of either an asymmetric explosion or asymmetries in the CSM. The lack of narrow lines within the first 2 days of explosion in the likely presence of CSM interaction may be an example of close, dense, asymmetric CSM that is quickly enveloped by the spherical supernova ejecta.2019ApJ...885...43Ahttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/885/43CatalogResearchIsServedByTAP VizieR generic servicerelated-toJ/AJ/128/16 : HIPASS Bright Galaxy Catalog (Koribalski+, 2004)J/MNRAS/372/1315 : UBVRI photometry of SN 2004et (Sahu+, 2006)J/AJ/137/4517 : UVOT light curves of supernovae (Brown+, 2009)J/MNRAS/395/1409 : Type II-P SN progenitor constraints (Smartt+, 2009)J/ApJ/751/4 : Radial velocities of massive stars Cyg OB2 (Kiminki+, 2012)J/other/Sci/337.444 : RV curves of Galactic massive O stars (Sana+, 2012)J/ApJ/756/173 : Photometry type II SNe 2005ip & 2006jd (Stritzinger+, 2012)J/other/Nat/494.65 : SN 2010mc outburst before explosion (Ofek+, 2013)J/MNRAS/442/844 : BVRI light curves of type II-P supernovae (Faran+, 2014)J/ApJ/789/104 : SNe IIn observations and properties (Ofek+, 2014)J/MNRAS/438/L101 : First month on SN 2013ej (Valenti+, 2014)J/ApJ/799/215 : 26 type II-Plateau supernovae parameters (Pejcha+, 2015)J/A+A/579/A40 : PESSTO catalog (Smartt+, 2015)J/MNRAS/449/1876 : Photometric observations of SN PTF11iqb (Smith+, 2015)J/ApJ/811/117 : R-band PTF observations of SNe IIb (Strotjohann+, 2015)J/AJ/151/33 : UBVRIz light curves of 51 Type II supernovae (Galbany+,2016)J/ApJ/820/33 : R-band light curves of type II supernovae (Rubin+, 2016)J/MNRAS/459/3939 : Type II supernova light curves (Valenti+, 2016)J/MNRAS/461/2003 : SN2013ej light curves 1 to 450d after explosion (Yuan+,2016)J/ApJ/835/166 : SNe type II from CSP-I, SDSS-II, and SNLS (de Jaeger+, 2017)J/A+A/611/A25 : Updated Type II supernova Hubble diagram (Gall+, 2018)J/ApJ/861/63 : Type IIP SN 2016bkv LCs and spectra (Hosseinzadeh+, 2018)J/A+A/614/A12 : VLTI/PIONIER observations of CE Tauri (Montarges+, 2018)J/ApJ/853/62 : Optical & NIR spectra and LCs of SN2016ija (Tartaglia+,2018)J/ApJ/873/L3 : NUV to NIR photometry of type IIP ASASSN-16at (Bose+, 2019)J/ApJ/875/136 : BVRI, spectra & IR obs. type II-P SN2017eaw (Van Dyk+, 2019)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/885/43https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/885/43http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/885/43https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/885/43https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/885/43http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/885/43GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapOpticalInfrareddefaultJ/ApJ/885/43/table1SN 2017gmr optical photometryrecnoRecord number assigned by the VizieR team.
