Monitoring a Star Explosion

Night Sky News Fall 2013

The constellation Delphinus the Dolphin  which is visible in the late Summer and early Fall is the area in the sky where a star went into a nova type explosion.

The event was first detected by an amateur astronomer.  We were able to pick up the spectra showing the site of the explosion 1 month after the event.
