Khandrika and W. Li report the LOSS discovery of an apparent supernova on unfiltered KAIT images. SN 2005lt is located at R.A. = 11h42m26s.21, Decl. = +20d07'05".0 (equinox 2000.0), which is 24".5 east and 5".4 south of the nucleus of the galaxy MCG +03-30-51. Available magnitudes for 2005lt: May 29.20 UT, [19.0; Dec. 10.55, 15.7; 12.54, 15.7 (under poor conditions, but the new object was obviously detected).

Anupama, Indian Institute of Astrophysics, report that a spectrogram (range 350-720 nm) of SN 2005lt (cf. IAUC 8645), obtained on Dec. 16.01 UT with the Indian Astronomical Observatory's 2-m Himalayan Chandra Telescope (+ HFOSC) shows it to be a type-Ia supernova. The expansion velocity, derived from the minimum of Si II (rest wavelength 635.5 nm), and adopting the NED recession velocity of 5974 km/s for the host galaxy (from Haynes et al. 1997, A.J. 113, 1197), is about 7500 km/s.
