- Does not meet all three thresholds
The viewing time is sunset plus four-ninths of the Moonset lag. This planner’s geometry screen requires a waxing Moon no more than 25% lit, altitude at least 5°, elongation at least 10° and lag at least 40 minutes. Use a clear, unobstructed western horizon; haze and clouds can hide a crescent even when these thresholds are met.
