Morska

From Memory Alpha, the free Star Trek reference

Morska was a Klingon planet on which a subspace monitoring outpost was located.

The USS Enterprise-A passed near Morska when on course to Rura Penthe to rescue Kirk and McCoy in 2293. Fortunately, Communications Officer Uhura was able to convince the technicians at Morska that the Enterprise was a legitimate Klingon ship. (Star Trek VI: The Undiscovered Country)
