The `aurora` platform uses the [NOAA Aurora Forecast](https://www.swpc.noaa.gov/products/aurora-30-minute-forecast) service to let you know if an aurora might be visible at your home location in the next 30 minutes, based off of current solar flare activity.
This service gives a number 0-100 representing the current likelihood of visible auroras at your latitude/longitude. By default this sensor is set up to trigger when the reported likelihood for your location is > 75. It updates every 5 minutes.
{% include integrations/config_flow.md %}
You can configure multiple locations by adding the integration multiple times.
## Options
Once installed you can adjust the threshold for this location by clicking on the Options link on the integration.
## Sensors
The integration will add a two sensors for each location you configure:
|Sensor Type|Values|Description|
|-|-|-|
|binary_sensor|on/off|on = high chance of Aurora visibility, off = low chance of visibility|
|sensor|% value|Percentage chance of visibility|
