Notes

Comet Holmes is a periodic comet that was discovered in 1892 by British amateur astronomer Edwin Holmes. This peculiar comet has a track record of outburst events and was actually in such a state when discovered in 1892, having already passed its perihelion point by five months and closest approach to the Earth by nearly a month when it suddenly brightened and was detected by Holmes. The 2007 outburst was a spectacular one, with the comet brightening from about magnitude 17.5 to about 2.6 in a little over a day. That’s a brightness increase of over 900,000 times!
