Rubin alert examples

Caption

As new images are taken by the Rubin Observatory, specialized software automatically compares each one with a template image. The template image, built by combining images Rubin has previously taken of the same area in the same filter, is subtracted from the new image, leaving only the changes. Each change triggers an alert within minutes of image capture.
