> Outbursts have been seen twice, reaching magnitude 2.0 on May 12, 1866 and magnitude 3.0 on February 9, 1946,[16] although a more recent paper shows the 1866 outburst with a possible peak range of magnitude 2.5 ± 0.5.[17] Even when at peak magnitude of 2.5, this recurrent nova is dimmer than about 120 stars in the night sky https://en.wikipedia.org/wiki/T_Coronae_Borealis https://en.wikipedia.org/wiki/T_Coronae_Borealis magnitude 2 is not very bright. Still brighter than stars in the neighboring Hercules
