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. Description: A comprehensive optical and near-infrared (NIR) data set has been collected on SN2017gmr, with several major Super Nova (SN) collaborations contributing data. These include the Las Cumbres Observatory's Global Supernova Project, the NOT (Nordic Optical Telescope) Un-biased Transient Survey51 (NUTS), the Public ESO Spectroscopic Survey for Transient Objects (ePESSTO), the Texas Supernova Spectroscopic Survey (TS3), and the Tsinghua Supernova Project. The second section of the article briefly lists the instruments/telescopes used in obtaining data for SN2017gmr.
