AuroraMe — Aurora Forecast

Get smart alerts before aurora appears in your area

Northern lights forecast on your Chrome toolbar. AuroraMe shows whether the aurora borealis — or the aurora australis in the south — is likely to be visible right now in the city you pick, with the current Kp index on the badge. THE BADGE The badge shows the current Kp value, rounded. The badge colour is the aurora verdict for the city you picked: Green — Bright Amber — Visible Orange — Faint Red — Unlikely Grey — no forecast available right now When there is no forecast to show, the badge shows a dash instead of a number, on grey. It is never empty. These colours run the opposite way to a normal alert badge, and that is deliberate. Red is the ordinary state on a quiet night: it means there is nothing worth going outside for. Green is the state worth acting on. Grey means the forecast could not be loaded — never that conditions are bad. THE POPUP Click the badge for the verdict in words, the city it applies to, and when it was last updated. Behind the "i" are the factors the verdict is built from: Kp index, cloud cover, moonlight, darkness, and how far you are inside the aurora zone (magnetic latitude). Pick your city in the search box in the popup. The forecast refreshes in the background every 15 minutes, and again whenever you open the popup or change the city. NOTIFICATIONS Off until you turn them on. When enabled, you get one desktop notification when the verdict for your city rises to visible. It does not repeat while conditions stay good. A switch in the popup turns them off again at any time. PRIVACY No account. No sign-in. No tracking, no analytics, no cookies, no content scripts, and no access to the pages you browse. The extension talks to exactly one server — the AuroraMe forecast API. It sends the city you chose, and, while you are typing in the search box, what you type there. ABOUT THE MOBILE APP The verdicts, the colours and the wording are the same ones the AuroraMe app uses on iOS and Android. The extension itself is free and complete: it does not check an entitlement and it does not lock anything. The popup names what the mobile app adds — unlimited saved locations, a 72-hour forecast, a 27-day activity timeline — and links out to it. Nothing is purchased inside the extension. https://auroraforecast.me
