The last outburst of T occurred February 9th 1946…80 years ago.  Renowned variable star observer, Leslie Peltier missed the event due to an illness and went back to bed, and seemingly never forgave himself.  He had planned his observation for 2:30 AM.

Coordinates: RA: 15h 59m Dec. +25º 55m

The first observed outburst of T Corona Borealis occurred on the night of May 12th 1866, when the star was about the brightness as Alpha Coronae, magnitude 2.2. (Source: Burnham’s Celestial Handbook; Volume Two; Page 708
