Аннотация:Nova Eri 2009 (KT Eri), is an He/N nova discovered by K. Itagaki on 2009 November 25.5 UT (CBET #2050), well past its optical maximum. Pre-discovery lightcurve was reconstructed by Hounsell et al. (2011, ApJ 724, 480) from satellite SMEI observations, highlighting a rapid rise in magnitude following the first detection on 2009 November 13.12 UT and a sharp maximum reached on 2009 November 14.67 UT, after which the nova immediately entered a rapid decline characterized by t(2) = 6.6 days.
