Why this recommendation
- Waxing Crescent at 6% illumination. Only a slim crescent is lit; look soon after sunset or before sunrise, close to the horizon.
- The Moon does not rise above the horizon during the next 24 hours at this location.
- No moonrise is predicted within the next 48 hours — a polar condition is possible.
Limitations & methodShowHide
- The viewing score is a convenience index, not a scientific measurement of sky quality.
- The Moon disc on this page is phase-correct but its orientation and surface detail are schematic; libration and parallactic angle are not modelled.
Local context
Moonwatching from Longyearbyen
At 78.2° N, this is a polar location. The Moon may stay above or below the horizon for more than a day, and the app will say so rather than invent a rise time. The disc is shown in northern-hemisphere orientation with a NASA LRO surface.
All times on this page use the IANA time zone Arctic/Longyearbyen, including daylight-saving changes. The weather forecast is for coordinates 78.22°, 15.65°. It can differ across a large metropolitan area.
