This comet unexpectedly brightened to third magnitude as it came from behind the sun on its way back out of our solar system. Initially, only observers in the southern hemisphere could enjoy the sight, but by late June the comet became visible from the northern hemisphere as well. When this image was taken, the comet had moved well north and was passing through the constellation of Pegasus. By the time this images was taken, the comet was easily seen with binoculars. A week after this image was taken, the comet had faded to sixth magnitude as it raced away from us back out to the cold environs of the Oort Cloud.
