Solar Activity Pro vs Eclipse Timer

Solar Activity Pro — your space weather companion Geomagnetic and solar activity can affect how you feel — from headaches and fatigue to general malaise — and can also influence technical systems such as GPS, satellites, and radio communications. Solar Activity Pro helps you stay informed about what is happening on the Sun and around Earth, whether you are an aurora hunter, a space weather enthusiast, or simply curious about solar storms. NEW: Aurora Map Explore Northern Lights probability on an interactive world map powered by NOAA OVATION data. Tap anywhere to see aurora probability, coordinates, and place name. Customize the map with multiple styles, cloud overlay, aurora intensity, and your current location. Stay informed - Push notifications for NOAA space weather alerts - Alerts screen with solar activity warnings and impacts timeline - Live dashboard with key gauges (solar wind speed, density, Bz, Bt, Kp, Dst, magnetometer, electron flux) - Boulder Kp index with trend direction Forecasts - Kp and Ap index forecasts - Predicted solar wind - 24-hour and weekly outlooks - Solar activity reports - Sunspot number and F10.7 radio flux forecasts Observations (last 24 hours) - Solar wind speed, density, and temperature - Magnetometer data - Electron and proton flux Aurora - Interactive Aurora Map (NOAA OVATION) - Northern and Southern Lights models - Tonight and tomorrow aurora outlook - Live aurora cameras - aurora forecast for major cities around the world - you can select your city on the map to get an aurora forecast - aurora forecast powered by artificial intelligence Models & maps - Solar wind velocity, density, and pressure animations - Global and regional ionospheric perturbation maps - Total Electron Content (TEC) — global and North America - CTIPe, WAM-IPE, and GloTEC models Media - Aurora cameras from observation stations - Latest solar images (including DSCOVR) - Space weather videos Knowledge base - Phenomena — 16 illustrated topics: aurora, coronal holes, CMEs, geomagnetic storms, solar wind, flares, sunspots, ionosphere, radiation belts, cosmic rays, and more - Impacts — how space weather affects GPS, HF radio, satellites, power grids, and satellite drag Widgets Add live data to your Home Screen: - Planetary Kp index - Space weather conditions - DSCOVR solar view - Latest X-ray flare event - Observations - Aurora cameras - Solar images Access to the application is carried out through a subscription system.

Eclipse Timer computes precise contact times for solar eclipses at any location you choose — down to the second. Pick an eclipse from a catalog spanning 1900 to 2100, drop a pin on the map or use your GPS, and instantly see when each phase of the eclipse begins and ends at your exact location. FEATURES • Browse 200+ solar eclipses from 1900 to 2100 — total, annular, partial, and hybrid — with search and filtering by year, date, type, or catalog ID. • Tap the map, drag a pin, or use GPS to set your observer location. The engine computes results for your precise coordinates. • View all five contact times (C1, C2, Greatest Eclipse, C3, C4) in both UTC and your local time zone. See eclipse type, magnitude, and duration of totality or annularity at your chosen spot. • Live countdown timer shows days, hours, minutes, and seconds until the next eclipse event for the selected eclipse. • Set notification reminders for eclipse contacts — one hour before, ten minutes before, or at the moment of each event. Choose between system sounds, vibration, or spoken voice (TTS) alerts. • Interactive map overlays show the eclipse's visible path and central line so you can see where totality or annularity occurs. • NASA preview animations let you visualize each eclipse before it happens. • Save favorite locations for quick access across different eclipses. HOW IT WORKS Eclipse Timer uses the classical Besselian elements method — the same mathematical framework used by professional astronomers — to compute local eclipse circumstances. The engine evaluates polynomial shadow geometry at your observer coordinates to determine exactly when the moon's penumbral and umbral shadows reach your location. All computation happens on your device. Your location is never sent to any server. PRIVACY Eclipse Timer requests location access only when you choose to use GPS. Your coordinates stay on your device and are used solely to compute eclipse times. The app contains no ads, no analytics, no tracking, and no user accounts. See our full privacy policy for details. Whether you're planning a trip to see totality, checking if a partial eclipse will be visible from your backyard, or exploring historical eclipses — Eclipse Timer gives you the precise timing data you need.
