Either.

This could have been taken either in the morning, when the sun was rising above the horizon or in the evening, when the sun was setting beyond the horizon. I guess it totally depends on how one sees it, much like the half cup of water scenario, some see it as half full (optimistic, supposedly) while others see it as half empty (pessimistic, supposedly as well). So, what say you, sunrise or sunset?

p/s: Yeah, I know that I can easily check on the date and time but I couldn't be bothered to re-transfer the images and the wife is busy Bejeweled-ing on the iPhone.
