At the end of the last episode of season 2, the seventh signal shows up.
As I understand it, this signal is created by
Michael on her return to "the present".
Therefore, I would expect the crew of the Enterprise to be way more excited and head straight for her.
The only thing is the distance, apparently the signal is 51,000 lightyears away. That seems like a lot but I have no idea whether that distance can be traveled in any reasonable amount of time with a warp drive.
