    I have a quick question on the technical definition of sunset - the course links off to an almanac but I was hoping it would be simpler - i.e. as soon as the lowest point of the sun hits the horizon that's sunset and it's evening civil twilight for 30 minutes (and the reverse for morning). And if you google it and get a time, do you know if that's the same time as used by FAA? Thanks! Brian P.S. - great course BTW, learning a lot and it's easy to get through.
