Post Monoceros V838 - light echo timelapse
I expect you've seen this before - it's fairly old news. Not only was it a scientifically significant event in astronomy but they also made it into a timelapse.

Its light curve is here,

The physics is quite interesting, as you don't often get the chance to see light-echoes (as light travel times are usually so much shorter than typical timescales of luminosity transients - or there isn't sufficient scattering (i.e echo) to see anything interesting).

Woah! That is so cool! I'd never even heard of light echos- that was mind blowing trying to picture it at first, then the wikipedia diagram cleared the confusion. Thanks for posting, I don't frequent APOD nearly as much as I should- they have some awesome stuff on there.
