The suggestion by Oort that the Cygnus loop, an object of a diameter of about 3° whose brightest parts are NGC 6960 and NGC 6992, is an expanding supernova shell slowed down by interaction with the interstellar medium has led to an increased interest in objects of this type. As better information on the Cygnus loop becomes available, it seems to become increasingly probable that Oort's suggestion provides an acceptable interpretation.
