There are many aurora alerting services. What purpose does Aurora Sentry serve?
There are several very good aurora alerting services. Most send alerts by email and work very well. However, email can get delayed, and (in some cases) only one alert is sent at the onset of a storm. Aurora Sentry provides a more or less continuous flow of real time data which is useful in monitoring the progress of a storm. A combination of both the email services and frequent checks of Aurora Sentry is a good idea for those who want to make sure they don’t miss an aurora event.
