I think Kepler also saw a supernova, after Tycho’s death, but I don’t remember where in the sky it was visible.
Jan Brunowski, Johannes Kepler's assistant, first observed the phenomenon in October 1604; Kepler studied it until early 1606, when the supernova was no longer visible to the unaided eye. At its greatest apparent magnitude (about -2.5), the exploding star was brighter than Jupiter.Wow, you're really up on this stuff! Here I've always thought SN 1054 was the only one discovered by naked eye in the last 1,000 - 1,500 years or so.Kepler's Nova | supernova | Britannica
