Upcoming Comet To Be Brighter Than Moon

From Astronomy Now:

A new comet has been discovered that is predicted to blaze incredibly brilliantly in the skies during late 2013. With a perihelion passage of less than two million kilometres from the Sun on 28 November 2013, current predictions are of an object that will dazzle the eye at up to magnitude —16. That’s far brighter than the full Moon. If predictions hold true then C/2012 S1 will certainly be one of the greatest comets in human history…

Well, guess I should mark the calendar. This sounds like something I won’t want to miss. How could you miss something that will be “one of the greatest _____ in human history”?
