In 2371, the quantum singularity from a cloaked Romulan D'deridex-class warbird was detected orbiting Deep Space 9 in a "roughly elliptical fashion". The station's crew was able to track the singularity by using its tetryon emissions as a guide, and found that at certain points in its orbit, the singularity radiated temporal energy at a specific wavelength that caused Miles O'Brien to experience random time shifts into the future.
