These numbers make it an easy target for backyard telescopes.
Discovered on May 19th by amateur astronomer Koichi Itagaki, the supernova is located in the constellation Ursa Major, right here. Take a look!
Update 22 May 2023:
"This is best supernova in a decade," says Eliot Herman of Tucson, Arizona. "It has tripled in brightness in only 24 hours." At this rate, it will soon rival or outshine the spiral galaxy's core.
Astronomer Yvette Cendes of Harvard's Center for Astrophysics says the supernova should continue to brighten for another day or so. "We think it will peak around magnitude +10, although it is hard to be certain."
