Ever step outside on a whim and just happen to catch the northern lights? Neither have we. Aurora is here to help. It reads real space weather data from NOAA and tells you straight: are the northern lights actually visible from where you are, tonight and the two nights after. When the answer is no, it just says so. Pick the abstract halftone chart or a real map centered on your own sky, and choose your voice: plain and factual, or a space physicist who has a hard time staying calm once the numbers turn good. Install (don't Fork!) to receive future updates.
