The easiest way to check the journal would be to jump to the system that is 4Ly away, and then log out. Log in, jump to the UFO system, open the FSS and do a Discovery Scanner honk, close the FSS, exit the game. In the journal folder C:\Users\{username}\Saved Games\Frontier Developments\Elite Dangerous the most recent journal file will be that one. There is a lot of information about your commander that is loaded into it when you first log in which you don't have to/might not want to share, so you can search the file for "event":"FSDJump" that is the line where you initiate the jump to the UFO system.
You could copy and paste everything from then on out to a txt file and look through it, and/or attach it here to see if anything stands out. It probably won't on an initial scan, but you never know.
