The aurora service is a server which provides geomagnetic storm information in Prometheus format provided by querying the NOAA/NWS Space Weather Prediction Center. The API is queried each time the Prometheus endpoint (at /metrics) is queried. The shell installer can automatically add a systemd unit file and start the server.
I made this because I was tired of missing geomagnetic storm alerts, and I really want to see the Aurora Borealis some day. I figure if I set up alerts on the same system I use to monitor my infrastructure it will help.
