WorldPulsePro vs Aurora Forecast 3D

Rotate the globe, zoom in, out, tap to see maps, see the real time cloud cover on our living planet, watch the day/night time line move. Oh and see if you can reach out and tap every country world wide. Now with REAL WEATHER data for all the capital cities and ad-hoc queries as an in-app purchase. Our Pro version adds to our unique application that lets you send electrons to all* the countries in the world that have high level internet domain names, by offering faster and more accurate pinging plus more globe detail on IOS devices that support it. From your iOS device you can reach out and touch every country in the world with a few electrons, then see how long it takes them to respond. You'll never have to leave home, but you can touch them ten thousand kilometres away, and see them respond. Sites are actually located in their respected countries you will find that when you send electrons to Gibraltar they arrive in Gibraltar, not at a server in the United Kingdom, or at a cloud computing centre in the USA. Additionally we show very accurate weather data and two day forecasts. For free you get weather information on country capital cities.

The Aurora Forecast 3D is a tool to track down where the aurora is located in the sky from any location on planet. It renders Earth in 3D with rotation and scaling at your fingertips. You can select locations and make your own ground - station list. The Sun illuminates the globe as it updates in near real-time. The short term forecasts are up to +6 hours, while the long term forecasts are up to 3 days ahead in time. They are updated when the app is active and connected to internet. An Aurora Compass is included that shows where the auroral oval [1,2], the Moon and the Sun are located as you look up at the sky from your location. The phase and age of the Moon is also visualized in the compass. By zooming out in the 3D view port, satellites, stars and planets appear in their orbits [3] around the Sun. FEATURES - 3D view port of Earth. - Solar illumination of the Earth and the Moon. - Aurora oval size and location in real time. - Day side location of the red Cusp. - Forecasts based on predicted Kp index estimated by the Space Weather Prediction Centre (NOAA-SWPC). - Includes a 2.4 million star map [4]. - City light texture [5]. - Earth, Sun and Moon textures [6,7]. - Sky view module to track planets and stars [8]. - 3-day space weather condition forecast as news ticker. - Two-Line Element (TLE) satellite orbit calculations [9]. - Skyview navigation. - 3D Laser Star pointer to identify star signs. - Sounding rocket trajectories. - Sun and Moon daily elevation plots with rise and set time. - Epoch selection for magnetic pole position [10] - Ovals based on polar orbiting satellites data [11] - Target web links added to satellites, stars, planets and position. - All-sky camera links to the Boreal Aurora Camera Constellation (BACC). - Sky color animation [12,13]. - Zhang and Paxton ovals [14]. - Earth shadow calculations in twilight - Youtube demonstration.
