The Glendale Skye Aurora Alerts App

Get the UK's only 100% 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 in the UK.

• Totally free of charge.
• Optimised to work in remote areas where mobile signal is extremely weak. It will run quite happily over 2G in remote parts of Scotland.
• Minimal bandwidth usage.
• Minimal space on your phone.
• To reduce data usage, all graphs are load-on-demand and only refresh while you are using them.
• Also, works in Chrome and Firefox Browser on any Desktop PC or Laptop.

LIVE STATUS REPORTS

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 ALERTS

Push notifications of alerts from my Glendale Skye Auroras Facebook Page on any device using the Google Chrome or Firefox browsers (not iOS). Tells you how high the aurora will appear at your location. Status reports through 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.

SUBSTORM TRACKER

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.

DATA FEEDS

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 the TGO, IRF and AuroraWatch UK's magnetometer at Lancaster University.

All your latest graphs and data from the ACE Satellite and the Space Weather Prediction Centre, together with the Norwegian-Line Stackplot from the TGO.

EXPANSION ALARM

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.

AUTOMATED ALERTS

Receive push alerts on your Android Phone, Chrome Browser on Desktop or Firefox on Desktop when a substorm goes into expansion and when activity reaches strong enough thresholds to be photographed in the UK & Ireland.

To help serious aurora-hunters, alerts are prioritised so that people who use, and interact regularly with, the app are sent their alerts first.

TWILIGHT TIMES, COMPASS & POSITION

Tells you all the twilight times at your location, together with your latitude and also includes a compass to tell you which way North is.

Tells you exactly what times it will be properly dark where you are, accounting for moon and twilight.

TWILIGHT ARC / NOCTILUCENT CLOUDS

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.

LONG-RANGE FORECAST

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.

Compatibility

Optimised for the Chrome App on Android. Push alerts are only supported in the Chrome App on Android, and Chrome/Firefox Browsers on Windows PCs.

• Chrome App on Android.
• Safari on iPhone & iPad.
• All modern desktop browsers.

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, which is currently only supported fully by the Chrome Browser on Android and partially on Chrome & Firefox for Windows. 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.
