S. Chakraborti, Tata Institute of Fundamental Research, Mumbai; T. Prabhu, Indian Institute of Astrophysics, Bangalore; G. C. Anupama, Indian Institute of Astrophysics, Bangalore; A. Kaur, Indian Institute of Astrophysics, Bangalore; G. Uday Kumar, Indian Institute of Astrophysics, Bangalore; and A. Ray, Tata Institute of Fundamental Research, Mumbai, report that 2008in (cf. CBET 1636) is a type-IIP supernova. Medium-resolution slit spectroscopy (range 400-700 nm; median filtering width 3.0 nm) with the Himalayan Chandra Telescope at the Indian Astronomical Observatory (operated by the Indian Institute of Astrophysics) obtained on Dec. 29.00 UT reveals broad H_alpha emission from the location of the supernova; with the help of the SNID code (Blondin and Tonry 2007, Ap.J. 666, 1024), the spectrum of 2008in is found to be most similar to that of SN 2005cs at age 1.0 days past maximum (age from explosion 7.0 days). The spectrum also similar to that of SN 1999em at 1.6 days before maximum (age from explosion 8.3 days).
