AOTEAURORA

Most aurora apps tell you the sun is active. AOTEAURORA tells you whether you will actually see anything tonight, from where you are standing. WHY THIS ONE IS DIFFERENT A geomagnetic storm behind heavy cloud is worth nothing. AOTEAURORA scores space weather and local viewing conditions together, so you are not driving two hours to stand under an overcast sky. BUILT FOR NEW ZEALAND SKIES New Zealand sits at a lower geomagnetic latitude than its position on the map suggests, which is why forecasts built for the northern hemisphere mislead here. AOTEAURORA is calibrated against reported New Zealand sighting thresholds, from Southland and Otago through Canterbury to Taranaki and Auckland. WHAT IT LOOKS AT Solar wind speed, density, and the Bz component that decides whether energy couples into our atmosphere Planetary K index, current and forecast Hemispheric power and the position of the auroral oval Live magnetometer readings from inside New Zealand Substorm activity Cloud cover for your location, hour by hour Darkness windows and moon phase, because a bright moon washes out a faint display THE DETAIL WHEN YOU WANT IT Open any figure to see what it means, where it came from, and how it is trending. Interactive charts, a draggable globe showing the auroral oval, and a four day solar wind forecast. HONEST BY DESIGN No accounts, no sign up, no advertising, no tracking Rates observing conditions rather than promising a sighting, because aurora can appear with little warning and fade just as quickly Available in English, Hebrew, Spanish, German and Chinese DATA SOURCES NOAA Space Weather Prediction Center, GeoNet and Earth Sciences New Zealand, and Open-Meteo. AOTEAURORA cannot guarantee an aurora. What it can do is tell you honestly whether tonight is worth your time. Published by Aoteaurora Limited, New Zealand.
