Shine a spotlight in the direction of Saturn, or build a fire. I wonder how much light you'd need to emit to have a noticeable effect? The Narrow Angle Camera is 1024x1024 I think[1], I have no idea what integration time, so my first guess is that we need to get a major city to riot/burn, or start a forest fire. Hmm, on second thought, maybe I'd better just have a beer and wave like cdevroe.

- duskwuff 13y agoNot quite the same question, but related - XKCD did a "What If" on whether, if everyone on Earth shone a laser at the Moon, it'd be visible. (TL;DR: No.) http://what-if.xkcd.com/13/ http://what-if.xkcd.com/13/
