Hugora nebula

The Hugora Nebula

The Hugora Nebula was a stellar cloud that was located on the Federation's side of the Demilitarized Zone.

As part of an ambush on Maquis ships planned in 2370, Federation starships hoped to use the nebula as cover from Maquis sensors. (TNG: "Preemptive Strike")

According to Star Trek: Star Charts (p. 47) and Stellar Cartography: The Starfleet Reference Library ("Federation Historical Highlights, 2161-2385"), the Hugora Nebula was located in the Alpha Quadrant.
