Cleared one over the weekend. It managed to spawn an awesome 75k spod, and I managed to mine it all out. No disturbances either. Nice and quiet.
Unfortunately, this was our last grav site, but a new one spawned today, Nick tells me. It's the first such spawn in weeks as we worked our way down. I hadn't intended to open the last grav, but we had a visitor who warped to it himself, so it was open anyhow.
Working on capital ship parts for the Rorqual. Got about 1/3rd of them done, going to buy about 90 mil tritanium and 30 mil pyerite next time we're near Jita.
