Never mind the PANSTAARS disappointment. Comet ISON is brightening!
Comet ISON- due in November- is brightening significantly.
If the sungrazer survives its close encounter with Old Sol, it's really going to be something. Speculation has been that you'll be able to read by its light!
But perihelion is always dicey with sungrazers. The forces they experience when they whip around the back side of our local star are pretty severe. Everything depends on ISON not disintegrating- and there's every chance that it might.
But if it doesn, the Great Comet of 2013 could be one of the most spectacular in recorded history.
