Fair tonight
Hour by hour, local to Ānaiyūr. Colour encodes the score and nothing else; every other measurement is luminance.
Cloud tracks show clear sky — a longer bar is better. The figure inside each track is the raw measurement.
What are you doing tonight?
The same forecast, weighted for the target. Planetary work barely cares about moonlight; long exposures die on high cloud a visual observer would never notice.
Darkness and moonlight dominate. Faint fuzzies need a genuinely dark sky more than they need steady air.
Seeing is everything and moonlight is irrelevant. Bright targets punch through twilight, so darkness barely counts.
Tolerates soft seeing, but high cloud wrecks a wide frame and moonlight raises the background everywhere.
Needs conditions to hold still for hours. Sustained transparency matters more than any single good hour.
Naked eye, whole sky. Total cloud and moonlight are the only things that count.
