Description

Sh 2-113 and Sh 2-114 form, respectively, the southern and northern portions of a filamentary circle that resembles a supernova remnant. However, no supernova remnant appears to be recorded for this location.

Examining this region in hydrogen-alpha suggests that these nebulae are joined to the equally mysterious Sh 2-118 and Sh 2-123 in a long ridge of nebulosity south and south-east of Sh 2-117, the North American nebula. Sh 2-113, Sh 2-118 and Sh 2-123 have distance estimates of about 4000 parsecs. If this ridge is also at 4000 parsecs, it must be enormous.
