Supernova (Evans) in NGC 1316
Abstract
J. W. Menzies, South African Astronomical Observatory, telexes that his IPCS spectra (dispersion 4.5 x 10**-6) on Mar. 12.76 and 15.79 in the blue and on Mar. 16.77 in the red show this to be a typical type I supernova after maximum, with pronounced emission peaks at 390 and 460 nm and strong absorption near 615 nm. E. G. Tanzi, Istituto di Fisica Cosmica1 Milan; and M. Tarenghi, European Southern Observatory, Garching, communicate the following near infrared magnitudes, obtained on Mar. 24.00 and 25.03 UT: J = 14.5 +/- 0.1, H = 13.8 +/- 0.1, K = 13.6 +/- 0.1 (mean of two nights). The reference star was HR 1302 (assumed J = 4.28, H =4.12, K = 4.08). They add that the infrared colors are remarkably similar to those of Wischnjewsky's supernova in the same galaxy (IAUC 3548) at a comparable time after outburst.
