Hsiao, Florida State University and M. L. Graham (University of Washington) report that a spectrogram (range 390-710 nm, resolution 0.3 nm) of 2017iuu = ATLAS17nnf (J. Tonry, B. Stalder, L. Denneau, A. Heinze, H. Weiland (IfA, University of Hawaii), A. Rest (STScI), K.W. Smith, S. J. Smartt, M. Fulton, O. McBrien (Queen's University Belfast), obtained on Dec. 11.33 UT with the 1.82-m Plaskett Telescope of the National Research Council of Canada, shows it to be a normal type Ia supernova near maximum light. Cross-correlation with a library of supernova spectra using the "Supernova Identification" code (Blondin and Tonry 2007, Ap.J. 666,1024) suggests that 2017iuu is most similar to the normal type-Ia supernova 1994ae at 3 days past maximum light. There are several possible host galaxies with no published redshifts. Our solution yields a redshift of 0.043 for this object.
