SN 2008D is a supernova detected with NASA’s Swift X-ray telescope. The explosion of the supernova precursor star in the spiral galaxy NGC 2770 (88 million light years away (27 Mpc) was detected on January 9 2008 by Carnegie-Princeton fellows Alicia Soderberg and Edo Berger and Albert Kong and Tom Maccarone independently using Swift. They alerted eight other orbiting and ground-based observatories to record the event.
