At twilight, the sky can look truly extraordinary.
How early do you need to be to catch a sky like this? If sunrise is at 5:30am, you need to be at the sunrise point an hour before that. And depending how far you are from there, wake-up even earlier.
Does every sunrise light-up the sky like this? Unfortunately no. The conditions have to be just right. You need relatively good weather. You need interesting cloud formations just above the horizon. And the horizon itself needs to be clear so that light from an emergent sun can light up the bottom of these clouds. But knowing all that, every dawn is still a throw of the dice. You'll be lucky if every third sunrise you wake-up to looks anything like this. Such is life. Enjoy.
(Pixel-peepers: I was a little late this morning, but luckily, peak light waited for me. A good foreground eludes the unprepared, but a burning sky needs little introduction.)
