The Auroral Activity Now aurora spotting dashboard (accessed from here: https://www.tvcomm.co.uk/g7izu/auroral-viewing-probabilities/) has been in a process of refinement almost every day since it was launched over Christmas.

The page uses extensive data analysis to generate probabilities of aurora at high and mid latitudes, plus at a user location obtained either from the user’s device location or manual entry of lat and long. Nowcasts and forecasts are generated from NOAA alert files through text file parsing and logic combined with live data.

The dashboard will alert the user if a new version is published whilst they have a session open, else the latest version will load as soon as the page is opened or refreshed.

An alarm function is built in which provides alert tones and voice notification on the local device. Alert levels are selectable, along with a “moon filter” which will supress the alarm should the moon be illuminated more than the user selected value. Alarms can also be forward via Pushover to the user’s mobile device – a Pushover account on the free tier is required and the user must enter credentials via the settings pop up to make it work. In testing I’ve found that Pushover provides alerts with almost zero lag and is very reliable, as long as the page on the home machine is left active!
