# Weather Forecasting

Astro PM includes astronomy-focused weather: cloud, seeing, and transparency outlooks per site, organized around imaging nights rather than calendar days, plus a satellite loop for the synoptic picture.

### The Forecast Panels

Weather appears in two places: the **site weather panel** (Equipment) and the **Weather tab inside each project**. Both show the same engine: hourly cloud cover, computed **seeing** and **transparency** estimates, temperature, humidity, and wind, in your choice of °C/°F and a 7- or 14-day span.

### Nights, Not Days

Forecasts are grouped **noon-to-noon**, because an imaging night straddles two dates. Each night card summarizes the dark hours that actually matter, so “tomorrow night” means what an astronomer means by it.

### Satellite Player

The satellite view is a **GOES imagery frame player**: recent frames with a scrubber, synchronized with the forecast chart, so you can watch cloud fields move toward (or past) your site and judge the forecast against reality.
