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.

SET UP 23:30 · OBSERVE 00:00–04:00 · 4H · MEAN 41

Darkness and moonlight dominate. Faint fuzzies need a genuinely dark sky more than they need steady air.

00020406
SET UP 23:30 · OBSERVE 00:00–04:00 · 4H · MEAN 42

Seeing is everything and moonlight is irrelevant. Bright targets punch through twilight, so darkness barely counts.

00020406
MOONLIGHT IGNORED FOR THIS TARGET
SET UP 23:30 · OBSERVE 00:00–01:00 · 1H · MEAN 40

Tolerates soft seeing, but high cloud wrecks a wide frame and moonlight raises the background everywhere.

00020406
NO USABLE WINDOW FOR THIS TARGET TONIGHT

Needs conditions to hold still for hours. Sustained transparency matters more than any single good hour.

00020406
CLOUD NEVER DROPS BELOW 62%
SET UP 23:30 · OBSERVE 00:00–03:00 · 3H · MEAN 41

Naked eye, whole sky. Total cloud and moonlight are the only things that count.

About this forecast

Conditions for Lingao, China are computed from the MET Norway forecast model for these exact coordinates, combined with sun and moon positions we calculate directly.
