Just bagged my first H mass black hole. I've been doing a survey of them all around this area (mostly F masses, since there's thousands of them) but I started cross-checking with EDSM to see if there were any missing from the database under the AA-A ident and there were, but it seems even those that aren't in the database have been visited, so I was starting to lose hope there were any left. They all seem to have been discovered by the same CMDR so I'm assuming they were doing a systematic scan themselves, and the one I've discovered myself is the highest numbered on the list so far, so I'm hoping they might've only done so many and then moved on.
I'll check a few more out tomorrow from further down the list and see if they're still actually undiscovered, or if I just got lucky cos the other guy missed one out. If it appears they are discovered I might have to try a different tactic, or move to another sector (there looks to be good pickings in at least 2 others near me, so I'm gona check them all eventually).
