Tonight is for planning

The sky is staying closed.

None of the five observing modes reaches a reliable setup window. Skip the empty charts and use tonight to make the next clear session easier.

Make the next clear night easier

Three useful moves, no dead chart.

The forecast detail above remains available when you need the measurements. These are the useful next decisions.

About this forecast

Exact-coordinate weather, sky geometry and site context.

Full method →
Sources and scoring details openclose

Conditions for Zselic Starry Sky Park, Hungary 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.
