I've enjoyed astronomy for as long as I can remember. That goes back to 1973, spending a few late nights as a kid with a telescope on our front lawn staring into space for comet Kohoutek. Fast forward 50 years or so, and I put together an email alert service to let me know when the Aurora Borealis, or Northern Lights, are active in my area. It's now available for general access for anyone at https://www.customvisuals.com/services/aurora/. It is email alerts only, no spam, no marketing, you can pause or cancel the alerts at any time.
