Tonight’s sky, and why.
The Sky Quality Index (SQI) below is predicted from the current heuristic. Log what you actually see tonight so we can tell where it’s right and where it isn’t.
SQI and its Low–Exceptional tiers are experimental and still being calibrated against real observations — treat scores as a starting point, not a verdict.
