A gamma-ray burst spotted on 16 December 1999 was nicknamed the Beethoven Burst because it arrived on the composer's presumed birthday.

Its official name is GRB 991216. NASA reported that an astronomer gave it the nickname because it fell on the anniversary of Beethoven's birth, which is usually given as 16 December 1770. The burst came from more than 10 billion light years away, and NASA said it tied as the second brightest burst its BATSE instrument had recorded.
