Discovered in 1975, along with the Coma Supercluster, it lies in front of the Coma Cluster. It was the first void to be discovered, and is approximately 1/3 as far away as the much larger Boötes Void.
The evidence for such a "Great Void" is disputed by Smith and Huterer. They showed that the claims made of observational evidence for such a void from survey data neglected systematic effects, and did not account for a posteriori choices made in analyzing data.
The Southern Eridanus void is connected to the Eridanus void by a hole in the distribution of galaxies separating the two. A hole in the distribution of galaxies separating Sculptor and Southern Eridanus voids the size of (redshift) 1250 km/s appears to exist.
Corresponds to SRSS1 Void 3 and SRSS2 Void 5 This void is separated from the Eridanus Void by a sheet of galaxies. A hole in the distribution of galaxies separating Sculptor and Microscopium Voids the size of 1250 km/s appears to exist. A hole in the distribution of galaxies separating Sculptor and Southern Eridanus Voids the size of 1250 km/s appears to exist. The Sculptor Void lies next to the Southern Wall or Southern Great Wall.
The Taurus Void appears large and circular, and has walls of galaxies surrounding it. It lies next to the Perseus-Pisces Supercluster, and is the most visually identifiable. Several galaxies have been found to reside in the void, such as UGC 2627 and UGC 2629, both approximately 185 million light years away.

^This is the diameter of the largest sphere one can describe inside the void that contains no superclusters. Some voids have an elongated shape, so this diameter may underrepresent the size of some voids.
