Astronomy observing forecast from 7Timer! ASTRO — the metrics stargazers and astrophotographers use to decide if tonight is good for observing: cloud cover, atmospheric seeing (steadiness), and sky transparency, at 3-hour resolution out to 72 hours. Each point gets a human-readable label and an observing_quality verdict, plus a best_window summary of the clearest/steadiest hours. Keyless.

Parameters

`latitude`	number	yes	Latitude in decimal degrees, e.g. 38.9.
`longitude`	number	yes	Longitude in decimal degrees, e.g. -77.0.
