"1997 XF<sub>11</sub> – the true story" in The Journal of the British Astronomical Association Vol. 109, No.1 (February 1999) https://archive.is/20121220165604/www.britastro.org/jbaa/archive/marsden.htm. <br class="br">Context: It is probably a good idea to search, at some level, for asteroids that come to the Earth's general vicinity. But merely counting the asteroids found is not sufficient. It is desirable to follow up each discovery to examine whether it can or can not be a threat during the next century or so. Objects for which the threat cannot be eliminated should be singled out for special study, notably to the extent of searching for old images in photographic archives. 1997 XF11 was noteworthy for the apathy shown to it prior to the very widespead announcement in March. If proper attention had been given to it earlier, the circumstances that led to the announcement would never have occurred. Sometimes statistics will conspire to draw attention to a problem. Maybe they are trying to tell us something.
Famous Brian G. Marsden Quotes
“What we really need is a good scare.”
As quoted in "What We Need Is A Good Scare" by Steve Nadis at Omni internet (9 April 1997) http://www.astralgia.com/webportfolio/omnimoment/archives/live_science/minor_planet/index.html. <br class="br">Context: We have to beef up our searches, which are now pretty dismal, so we can find out about these things before we get hit. … It takes a dramatic event to get people's attention, and we thought the comet crash with Jupiter might have done the job. … we tend to ignore an extraterrestrial hazard that could reduce the planet to rubble. … What we really need is a good scare.

On the unprecedented brightening of Comet Holmes, as quoted in "Mystery Comet Explodes into Brightness" (26 October 2007) at Physorg.com http://www.physorg.com/news112622756.html. Within the space of a few hours between 23-24 October 2007 it brightened from a very dim and obscure object requiring powerful telescopes to see into one easily visible to the naked eye.
