Brown Jenkin said:I am not as sure about that. Claire had been videotaping herself months before that, Nathan had been flying for a long time, plus all the companty people and the Linderman-Petrelli group. There had to be lots of eclipses (and there are worldwide but they are rare for any given location) plus they made the powers out to be genetic so I don't see how an eclipse can trigger thier activation.
There was an episode from first season (called 6 months ago -- or something like that). In that, there was an eclipse and that night was the first time nathan flew (avoiding the car accident that crippled his wife) and claire's power first manifested too, etc
if lunar cycles can have effects on the body's natural processes, they may be stretching that to eclipses having the effect to 'awaken' some latent ability or such.
I'm not saying it's the end-all-be-all, but there is definatly some sort of correlation (also add in the meta-reason that an eclipse is a symbol for the series itself and therefore probably has some connection)
