Disagreements are highlighted. Sun/moon details: • Sun / Moon rise, set and twilight times. • Moon phase and elevation. Tools: • Aurora forecast, with worldwide and local data/maps. • ISS and satellite passes for your location, plus NASA’s ISS Live Feed. • Interactive Light Pollution map using World Atlas 2015 or Xasteria/VIIRS 2025 data. • Quick access to Clear Outside, Meteoblue, Windy, Astrospheric, Sat24, water vapor satellite imagery and more. Display Three display modes: 7Timer icon/graphic view, color-stripe view, or raw text. The left panel can be switched to icons, and summary icons and cloud layers are configurable in settings.
