Comet 17P/Holmes illustrated above while passing through the constellation of Perseus was discovered in November 1892 by Edwin Holmes when he accidently turned his scope for one last peek at Andromeda before he was about to call it a night during that fateful evening. Perhaps its most characteristic feature is its ability to exhibit very dramatic outbursts in brightness which was the case during its discovery in 1892 as well as late 2007 when it underwent a dramatic change in magnitude (from 19+ to 2.6) representing a million-fold increase.
