IK Pegasi B is considered the white dwarf most likely to supernova in our galactic neighborhood, although some professors (eg: Neil F. Cumins of Maine) thinks it might nova instead. (I agree with Professor Cumins) Questions: At about 150 light years distant would this faint star become visible to the unaided eye? In other words, if it goes supernova it will be brighter than a full moon but if it merely goes nova would we even notice, visually. 2nd question: Neutrinos precede core collapse supernovae (by as much as a day) which could serve as a warning. Is there known evidence that neutrinos precede type 1a (standard candle) supernovae? If so, when and where? 2nd part: Have we ever recorded a neutrino burst preceding a nova event? 3rd question: Are there any government protocols in place in the event of a nearby supernova? I just signed up to be notified in the event of a neutrino burst. Is homeland security or the defense department signed up. My concern is the EMP from a nearby supernova might destroy all unprotected satellites and knock all the jets and helicopters out of the sky. I love theory but really suck at researching on the internet. Thanks ahead of time for enlightening me.
