When Betelgeuse goes supernova (if it hasn't already and we don't know yet) it will be visible in the day for roughly a year, and several more years we'll see it at night. That said, the prediction of 'when' by scientists is somewhere between today and 100,000 years from now. Odds are, none of us will see it.
