The moon
Blue moon
A blue moon is the second full moon in a calendar month, or the third of four in a season.
The month kind is the popular one; Sol lists both, with the year's dates.
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.
Blue moon, where you stand.
You stand at the middle of your horizon. The dots are the moon’s path tonight, the moon lit as it is; the stage opens three hours after sunset. Slide through the night, or drag the sky to turn it.
How Sol measures it.
Because lunations run 29.5 days, a month of thirty or thirty-one can hold two full moons, which happens every two to three years. The colour has nothing to do with it; the phrase is old and meant 'rarely'. A moon can look blue after a great fire or eruption, when smoke of one particular size scatters the red — that is rarer still.
