The day
Dawn
Dawn is the twilight before sunrise, from when the sun is 18° below the horizon until its edge appears.
Its first stage is faint and starlit; its last, civil dawn, is bright enough to read by.
Golden hour, the twilights and the moon, where you stand.
Sol for iPhone is coming soon, with each of them for the place you stand, on your phone and your wrist.
Dawn, where you stand.
You stand at the middle of your horizon. The dots are the sun’s path today, warm where the light turns golden; the stage opens at twenty-five minutes before sunrise. Slide through the day, or drag the sky to turn it.
How Sol measures it.
The order runs astronomical, nautical, civil, then sunrise, each named for what it lets you do — see the faintest stars, take a sight, read a page. At mid-latitudes the whole passage takes about an hour and a half; at the equator, barely more than an hour, because the sun climbs straight up.
Make time for the light.
