What's the Titan Expedition rendezvous 2 systems name?

Didn't have the ship flotation yet so moved onto other systems. Completed everything in expedition except the deep water task. Now i have jumped to what seems like 100 systems with "water" in their name and have yet to find a water planet to dive. Even tried the Lithium trick on another post and it says its found in every system I am at. So definitely bugged now.

How can I get back to that rendezvous 2 system? Anyone got the name so I can poke around the system map until I find it?
