Struve's Lost Nebula (NGC 1554)

Struve's Lost Nebula was nebulosity reported by Otto Wilhelm Struve in 1868, and verified by Heinrich d'Arrest, in the vicinity of Hind's Variable Nebula (NGC 1555) in Taurus. Although given a separate catalogue number (NGC 1554) by Dreyer, it was not seen by observers a decade after Struve's discovery, nor has it been seen since. Modern sources, such as Sky Catalogue 2000.0 group NGC 1554 and NGC 1555 together as a single object, although 1554 is not visible on the Palomar Sky Survey plates. At the reported position of the Lost Nebula is a magnitude 14 star, 4' west-southwest of T Tauri. It appears that the Lost Nebula may have been a transient portion of the reflection nebula complex in this part of the sky.
