17P/Holmes is a periodic comet in the Solar System, discovered by the British amateur astronomer Edwin Holmes on November 6, 1892. In only 42 hours in October 2007, the comet brightened from a magnitude of about 17 to about 2.8. This represents a change of brightness by a factor of about a half million times, and is the largest known outburst ...

John Bortle created a predictive model to calculate if a comet would survive perihelion or not, known as the Bortle survival limit. Accoording to it, if the comet is brighter than H10 = 7.0 + 6q, where H10 is the absolute magnitude of the comet and q the perihelion distance in astronomical units, it was likely to survive. [5]
