Get the world's most accurate aurora alert app that has been designed by an aurora-hunter for aurora-hunters.
You won't find the unreliable Kp or ovation model data anywhere on this app. It is powered entirely by the most accurate data feeds that are used by expert aurora-hunters around the world.
Tell people what's occurring where you are in a single click. See who's shouted out tonight and how far south the aurora is being photographed.
Push notifications of alerts on any device using the Google Chrome, Firefox (not iOS) or Edge browsers. Forecasts and status reports throughout the evening detailing what is occurring in the night sky and what your chances are.
Only sends alerts when it is dark enough for the aurora to be seen, so you will not be bothered unnecessarily during the day.
This is the only app in the world that provides real-time tracking of geomagnetic substorms, which enables it to provide advance warning that auroras are developing and at crucial stages when the aurora is coming to its peak.
Simple, colour-coded indications of how good the Interplanetary Magnetic Field is looking. Tracking of negative Bz periods with indications of what times they will be hitting Earth and how strong they will be.
Includes live data feed from dozens of magnetometers around the world.
All your latest graphs and data from the DSCOVR, ACE & SDO Satellites and the Space Weather Prediction Centre, together with the Norwegian-Line Stackplot from the TGO.
This is designed for desktop PC users. Leave the app running permanently in a tab or window on your PC and it will start bleeping when a geomagnetic substorm goes into its Expansion Phase, so that you can head out and catch it at its peak.
Receive push alerts on your Android Phone and Chrome/Firefox/Edge Browsers on Desktop when a substorm goes into expansion and when activity reaches strong enough thresholds to be photographed in your country.
To help serious aurora-hunters, alerts are prioritised so that people who use, and interact regularly with, the app are sent their alerts first.
Tells you all the twilight times at your location, together with your geomagnetic latitude.
Tells you exactly what times it will be properly dark where you are, accounting for moon and twilight.
Constantly calculates the position and height of the twilight arc in which Noctilucent Clouds may be seen. Tells you the maximum heights above the horizon at which Noctilucent Clouds and Cirrus can be directly lit by sunlight. Sends alerts when NLCs are being seen.
Tells you when solar wind streams that gave us good auroras are going to rotate around again, with indications of how strong it was last time.
Works on all devices. iOS does not support push alerts.
This is a Web App, not a native app. That means it works on any device with a web browser. It is using the very latest HTML 5 technology for push notifications. It works fine on iOS in Safari but you will not get the push alerts. Adding it to your home screen packages it up as an app, so it will work just like any other app on your device, except it will not take up any space.
