17P Holmes outburst


Quoting Gary Kronk account on comets-ml :

This outburst is very similar to the outburst this comet
experienced in 1892, which led to its discovery by Edwin Holmes
(England) on November 6. He was turning his 32-cm reflector toward M31
and thought that galaxy had entered the field of his finder. Upon
looking through the telescope he saw a comet about 5 arc minutes across
with a bright nucleus. Several people expressed scepticism that Holmes
had discovered such a bright comet, but it was confirmed with the naked
eye by other observers on November 7.
