This is a high security magnetometric site found through exploration. Its signal strength is low (1.25%), making it difficult to scan down.
Upon warping to the site a popup appears and says: Ancient ruins stand silent and still in the cold vacuum of space, a sober reminder of times long since past. An analyzer module will be vital in gaining a deeper understanding of the numerous artifacts located here and finding something of value among the rubble.
6 Cans (Angel Debris)
5 frigates.
2 additional frigates might spawn when analyzing a can. The defenders need to be killed before accessing the can.

Message > Failing the scanning has triggered a booby trap.
