RSBLANCHARD  Little Snitch will probably NOT detect TCP port 47807 being served-up because it only detects OUTGOING traffic, and the outgoing destination port (which would be the originating port) could be something innocuous-sounding like port 80.

RSBLANCHARD  Yes, port 47807 is LISTENing on 127.0.0.1, and this is in the "Server" range, it being at, or below 49151 (3/4ths of the way to 65535). It is tcp4, which means, when ESTABLISHED, it is a full connection under IPv4 TCP.

IP=127.0.0.1 is a loop-back address, part of "localhost", so one would think that this is local to your machine.

However, this may NOT be the case, as "localhost" is also registered under two IPv6 addresses on your machine.

Furthermore, from all sources that I can find, port 47807 seems to be an unregistered port.

If anyone can tie this port to a particular process using a particular UNIX command, please let me know.
