Finger Lake Instruments cooled cameras are being used to survey the night sky looking for supernovae and other bright stellar events by comparing multiple images of as much of the sky as possible. The Ohio State University are leading a team that are doing things a little differently, rather than picking spots to observe they are observing the entire sky all of the time! The team initially collect data from an area and create a reference frame, then by repeatedly re-scanning each area and comparing the images any bright stellar event that occurs can then be noticed. This is the alarm call to investigate that area of the sky further.
