Tonight in context · local sky & season

October historically: 15.2 qualifying nights/month on average (2005–2024). Regional cloud and darkness history, not tonight’s probability or a comparison with the conditions score.

A qualifying historical night has at least 3 hours of astronomical darkness and mean nighttime cloud ≤30%. This does not measure steady air or target visibility. Seasonal history →

Saturn: about 9.0h above 20° during this observing night’s darkness. Longest sampled dark-time opportunity among our four planet targets; not a weather ranking. Planet times →

Position calculations use roughly 20-minute samples. Clouds, skyglow and local obstructions still matter. Milky Way timing →

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 00:30 · OBSERVE 01:00–06:00 · 5H · MEAN 36

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

TWILIGHT BEGINS 06:00SITE GLOW LIMITS FAINT TARGETS
SET UP 19:30 · OBSERVE 20:00–07:00 · 11H · MEAN 87

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

SET UP 19:30 · OBSERVE 20:00–07:00 · 11H · MEAN 47

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

SET UP 19:30 · OBSERVE 20:00–07:00 · 11H · MEAN 48

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

About this forecast

Exact-coordinate weather, sky geometry and site context.

Full method →20-year baseline →
Sources and scoring details openclose

Conditions for El Dorado, Arkansas, United States 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.
