KT Eridani

[6] The nova was discovered at 12:52 UT on 25 November 2009 by K. Itagaki at Yamagata, Japan with a 21 cm patrol telescope.

The peak magnitude, 5.4, was seen at 15:10 UT on 14 November 2009,[5] at which time it would have been visible to the naked eye.

It is classified as a very fast nova, meaning it dimmed rapidly after peak brightness.

[8] On 28 December 2009 (44 days after peak brightness) it was detected as a 0.21 milliJansky source at 5 GHz by the Very Large Array.

[10] In the most common nova systems, the white dwarf accretes matter from a main sequence star.
