The Eastern Veil Nebula (also known as Caldwell 33), whose brightest area is NGC 6992, trailing off farther south into NGC 6995 (together with NGC 6992 also known as "Network Nebula") and IC 1340.
The Veil Nebula is expanding at a velocity of about 1.5 million kilometers per hour. Using images between 1997 and 2015, the expansion of the Veil Nebula has been directly observed.
