Cloud tracks show clear sky — a longer bar is better. The figure inside each track is the raw measurement.

Tonight's limiting factor
When a clear gap is worth driving for

Ask how long the gap is relative to your setup time and your exposure length. A two-hour gap is a real session for a visual observer and close to worthless for someone doing four-minute subs on a target that needs three hours.

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 00:30 · OBSERVE 01:00–03:00 · 2H · MEAN 46

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

010305
CLOUD RETURNS 03:00
SET UP 00:30 · OBSERVE 01:00–04:00 · 3H · MEAN 48

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

010305
TWILIGHT BEGINS 04:00MOONLIGHT IGNORED FOR THIS TARGET
SET UP 00:30 · OBSERVE 01:00–02:00 · 1H · MEAN 42

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

010305
CLOUD RETURNS 02:00
NO USABLE WINDOW FOR THIS TARGET TONIGHT

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

010305
CLOUD NEVER DROPS BELOW 58%
SET UP 00:30 · OBSERVE 01:00–03:00 · 2H · MEAN 43

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

About this forecast

Conditions for Kyzyl, Russia 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 how dark the sky actually gets. Read the full method →
