Cosmic anomaly, seen in 0.5 Boystin.
Frigate rats spawn.
It contains multiple ore, mostly Ytrium. Great for getting Isogen in high sec. Valuable ores all around.
Ytrium, 0.6m3 (240 Iso) - Many rocks, two dozen, the field is mostly these. 1-20km3
Jet Ochre, 8m3 (1564 Mex, 1380 Iso, 368 Nox) - One rock, about 12,000m3
Pellucid Crokite (920 Pye, 2300 Mex, 920 Nox) - One rock, about 17,000m3
Eifyrium (266 Zydrine) - One rock, about 33,000m3
Ducinium (170 Megacyte) - One rock, about 22,000m3
It appears Ytrium is the best source of Isogen.
My Mackinaw full of 44km3 of Ytrium is 60 mil.
