I've seen an exploration Noctis once before and by seen, I mean vapourized. But we just happened to catch it on a Wormhole, not see it in it's un-natural habitat, scanning for sites. Now at least I have a screen shot to verify this rare beast exists, dropping into my system from HiSec and proceeding to burn 100+ km's off the connection, uncloaked, whilst probing the system.
I dispatched him, of course, and Bob was pleased. Another frozen husk to throw on His Holy pile.
