Analyse de l'application Mobile Observatory Astronomy pour le 24 février

Mobile Observatory: The Only Astronomy App with Real Horizon Data See exactly when celestial objects rise above YOUR hills and mountains. Mobile Observatory computes your actual local horizon using NASA topographic data - a feature no other astronomy app offers. Know precisely when the Moon clears that ridge or when Saturn becomes visible above the treeline. NEVER MISS A CELESTIAL EVENT Get push notifications for: - Aurora alerts when Kp-index spikes at your location - Solar flare alerts from GOES satellite X-ray data - ISS pass reminders with brightness and trajectory predictions - Daily celestial events including conjunctions, eclipses, and meteor showers - Custom event reminders via calendar integration REAL TOPOGRAPHIC HORIZON - AN ASTRONOMY APP FIRST Download NASA SRTM elevation data for your location and see the true profile of mountains, hills, and ridges blocking your view. All rise and set times are computed against YOUR actual horizon - not a flat mathematical one. Works completely offline after the initial download. AR SKY VIEW & TIME-LAPSE Point your camera at the sky to identify stars, planets, and constellations in real-time with augmented reality. Swipe the time slider to start a time-lapse animation and watch celestial motion unfold - planets crossing the sky, the Moon's monthly journey, satellite passes overhead. LIVE SPACE WEATHER DASHBOARD - Real-time aurora oval forecast with hemisphere selector - Planetary Kp-index chart for geomagnetic storm tracking - GOES X-ray flux chart showing solar flare activity over 3 days - NOAA space weather alerts for storms and radio blackouts - Hourly-updated NASA SDO solar images TONIGHT'S BEST Automatically generated list of the most interesting celestial objects and events visible from your exact location tonight - personalized recommendations based on your horizon and light pollution.
