Clear, dark observing windows tonight — Is tonight good for observing here, and when? The clear, dark windows of tonight, and of the next nights the hourly cloud forecast covers, for one place: astronomical night with the Moon down (or up, with moon "any"), under the MET Norway cloud forecast. The windows are the ones the CycleCalcs Observing Planner widget draws, and the rule below decides which count; the answer is the /api/observing-windows feed's. Returns summary (tonight in one sentence on the place's clock), go_tonight (true when tonight has a window that passes the rule), next (the first window ahead that passes, with start,…
