On December 14, 2013 it peaked at about magnitude 3.3, making it the brightest nova so far of this millennium.[4]

Nova Centauri 2013 was observed emitting gamma-rays between 7–10 December 2013 by the Fermi Gamma-ray Space Telescope.[5] The nova continued to brighten in gamma-rays and the peak coincided with the second optical maximum on 11 December 2013.[6]

The Swift Gamma-Ray Burst Mission detected X-ray emission from Nova Centauri 2013 on 18 and 25 February 2014 and 8 March 2014.[7]

In July 2015 it was announced that lithium has been detected in material ejected from Nova Centauri 2013. This is the first time lithium has been detected in a nova system.[8]{{Dubious|Talk section name|reason=The discovery of Lithium in another nova, Delphi 2013, was announced in February 2015, see https://www.sciencedaily.com/releases/2015/02/150219085831.htm|date=January 2018}} The amount detected was less than a billionth of the mass of the Sun.[8] This finding is significant because it supports a theory that the extra lithium found in Population I stars (compared to Population II stars) comes from novae.[8]
