DID YOU KNOW... you can sign up to the SNEWS mailing list ( https://lists.bnl.gov/mailman/listinfo/snews-alert ) and get a few hours' email warning of a visible supernova, including but not limited to Betelgeuse? If you gate email from SNEWS to bast out to your pocket pager (I am using 1990s-speak here) ... and a bit of luck, you might have enough time to be star-gazing the first emergence of light with the naked eye. Or just as practically, find a good livestream to watch. Project homepage ( https://snews.bnl.gov/ ).
The global neutrino detector network is a 'first' for detecting supernovas from an event that arrives slightly-sooner-than-light. Gosh that seems strange to say, almost like a joke. Amazing times!
It is the ultimate low traffic mailing list and has no archives, because an alert has never been sent since its inception. Supernova 1987A WAS detected by the network 3 hours hours before, but they only realized it after the visible event occurred. They are prepared now, when a threshold of hits across detector sites is triggered, the automatic alerts will go out without delay or human involvement.
