Catching Cosmic Signature/Mission runners can be hard if not impossible. This tactic has given me some kills in the past though.
If I jump into system and notice that some players are running a Cosmic Signature. I then probe it, at this point they have probably already warped out and got safe. I finish probing it, bookmark it and then jump out of the system. I wait about 5-10 minutes and then jump in and warp straight to the signature I probed, if I’m lucky I will catch them as they have just arrived back in it. Be aware of this tactic, if somebody has been probing your signature don’t go back to it straight away after they leave. Wait at least 15 minutes.
