The day
First light
First light is civil dawn in Sol's measure: the moment the sun reaches 6° below the horizon.
Photographers and birders mean it this way; it comes about half an hour before sunrise at mid-latitudes.
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.
First light, 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.
Sol uses the phrase for the civil threshold because that is when a place becomes usable without lamps — the same line the law draws. The morning's blue hour follows it, then golden hour, then the sun. Nearer the equator the sequence is compressed; in the north in summer it is spread over hours.
Make time for the light.
