Artinian Burst
The Artinian burst was a subspace anomaly of unknown origin detected as a bombardment of subspace energy against active warp bubbles. The burst originated around 40,000 lightyears from Home near the galactic core and traveled at around 2300 times the speed of light, far faster than the current method of faster-than-light communications which transmit at 970 times the speed of light. The energy does not appear to have been modulated, meaning it is unlikely to have been an artificial signal as opposed to a natural occurrence. No comparable event is known to have occurred before or since, and though extensive efforts have been made to glean more information on the origin and nature of the event, no further discoveries have been made.
Detection
Over a period of several weeks in early 298FA, various ships at warp with a specific energy configuration and logging capability detected a bombardment of subspace energy against their warp bubbles that lasted for around 70 minutes, with peak intensity occurring within the first few moments and slowly dissipating over the next hour. There was no tangible effect on the warp bubbles themselves. A total of around 700 vessels have shared their data on the event; due to the distribution of these ships and the exact point in time they each individually detected the energy, the origin and speed of the burst was able to be triangulated to a point near the galactic core.
