Rise/set searches are restricted to the actual local day, including 23/25-hour DST days. Civil, nautical and astronomical twilight use solar-center altitudes of −6°, −12° and −18°. A missing event is reported rather than inventing a sunrise.
Astronomy Engine 2.1.19 calculations, not direct observations. Rise/set uses the upper limb with standard refraction and a sea-level observer; terrain and local weather are not modeled.
Results are astronomical estimates, not a guarantee of visibility or a substitute for safe observation.
