(No pun intended)
I asked Mythi about this discovery and he confirmed that this is a Camelopardalis service ship at the entrance to an old mining base. It is a huge cave complex that has no connection to the CG base, and was put into use long before the CG base was implemented. Very interesting to see a Camelopardalis spacecraft so closely. Cheers!
