This is a high security magnetometric site found through Exploration. Ar 5%, its signal strength makes it moderately easy 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 artivacts located here and finding something of value amongst the rubble.
4 Cans (2*Angel Waste - Salvage, 2*Angel Debris - Analyser)
You will need a salvager and an analyser equipped to complete this site. If you leave (without taking precautions), the site will most likely despawn before you get back.
2 Gistii Outlaws, 3 Gistii Thugs were up upon warp in.
Other Angel pirates can spawn when opening cans.
