J. Parrent, Dartmouth College and Las Cumbres Observatory; with D. A. Howell, R. C. Thomas, P. E. Nugent, and M. Sullivan, write that a CCD spectrum (range 350-900 nm) of PSN J01573658-5748008 = SN 2011eb was taken with the Gemini South telescope on July 13 UT, indicating that this object is a type-Ia supernova within a few days of maximum light, based on comparisons to other spectra using "Superfit" (Howell et al. 2005, Ap.J. 634, 1190); the Doppler velocity of the Si II 635.5-nm absorption feature is about 11300 km/s, assuming a host-galaxy redshift of z = 0.02.
