What's the meaning of the ethereum Parity console output lines?

Question

Parity doesn't seem to have any documentation on what it's console output means. At least none that I've found which admittedly doesn't mean a whole lot. Can anyone give me a breakdown of the meaning of the following line?

Thanks.
