 Hello everyone. I searched and couldn't find an answer to this. Articles of some major events often say that telescopes around the world were notified to point to a certain location. I know there are apps for alerts to celestial events but I would love to know when the global "everyone, point your telescope to x" notifications happen. Is there any way to be looped in? Thank you very much for your time.
