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.

RA: 15h 59m Dec. +25º 55m

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

My “latest” cell photos as following: I hope to keep this effort up, but at the moment…only if I wake up in the early AM. It will be quite a while before Corona Borealis becomes an evening constellation. For those with an interest in keeping up with T, it is in excellent sky position at about 3:00 AM and later.

Following photos: I’ll post the most current or recent first, and drop off the last…maintaining about ten photos or nights for review via this post.

Where is T located in the constellation? The following photo is from wikisky.org and has T marked with an X and inside the box.

February 13th 2026 @ 4:48AM: Two cellphone photos as following. I woke up late. Corona Borealis is really high in the sky at this time…but in excellent position and above the light dome of Shelby.
