What can you actually do tonight?

This is GoodSeeing’s decision layer: the same forecast is weighted for your target and site darkness. Planetary work barely cares about moonlight; long exposures can fail on high cloud a visual observer would barely notice. Your choice is remembered on this device and becomes the default for new alert rules.

SET UP 23:00 · OBSERVE 23:30–05:30 · 6H · MEAN 89

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

23010305
TWILIGHT BEGINS 05:30
SET UP 23:00 · OBSERVE 23:30–06:30 · 7H · MEAN 88

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

23010305
CLOUD RETURNS 06:30MOONLIGHT IGNORED FOR THIS TARGET
SET UP 23:00 · OBSERVE 23:30–05:30 · 6H · MEAN 87

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

23010305
TWILIGHT BEGINS 05:30
SET UP 23:00 · OBSERVE 23:30–05:30 · 6H · MEAN 84

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

23010305
TWILIGHT BEGINS 05:30
SET UP 23:00 · OBSERVE 23:30–05:30 · 6H · MEAN 89

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

23010305
TWILIGHT BEGINS 05:30

Deep-sky visual is your current default.

About this forecast

Exact-coordinate weather, sky geometry and site context.

Full method →
Sources and scoring details openclose

Conditions for Hanle (Indian Astronomical Observatory), Ladakh, India are computed from the MET Norway forecast model for these exact coordinates, combined with sun and moon positions we calculate directly. The score weighs cloud cover by layer, atmospheric transparency, estimated seeing, moonlight and astronomical twilight. Site darkness is shown separately, then used only where artificial skyglow physically changes moon contrast, haze scattering, visual limits and target suitability.
