That system was first discovered for EDSM by Titus Balls on Jul 14, 2016, 5:34:32 PM.
It was named by the Elite: Dangerous community with the name of: Thargoid Site - Merope eastern limit

During June 3303 a large number of unknown structures of Thargoid origin were discovered on planets in the vicinity of the Pleiades cluster.
These structures are many hundreds of metres in diameter, and consist of a number of organic-shaped elements surrounding a central edifice. There is a clear visual relationship between the structures and the Thargoid vessels previously sighted.
Even more remarkable are reports that the structures encompass large subsurface complexes, accessed via the central edifice. Drone-like machines have also been seen roving the sites.
Professor Ishmael Palin, leading authority on xeno-biological research, has commented on the discovery of functional technology at the Thargoid structures.
“This revelation is significant not only because it gives us an insight into Thargoid technology, but because it confirms the long-posited connection between the Thargoids and the Unknown Artefacts and Probes. Unfortunately, we still do not know the exact purpose of these pieces of technology. Reconnaissance, surveillance, cartography? The specifics elude us, even while fresh discoveries are made.”
Meanwhile, Ram Tah, the engineer leading research into the lost civilisation known as the Guardians, has commented on reports of interaction between Guardian and Thargoid technology:
“The fact that Guardian artefacts react to the Thargoid device certainly seems to suggest some kind of prior contact, and although we know very little about Thargoid history, interaction between the two races is entirely possible. But the negative nature of the reaction could be a sign that the relationship was not entirely peaceful.”
This particular system contain Unknown Structure US 026:
This structure is part of a larger network of sites, perhabs centered on Merope in the Pleiades cluster, and apparently connected via alien machinery. This particular site marks the eastern limit of sites found to this date.
