Reading this warning

DNC (Digital Nautical Chart): A reference to one of the regions of NGA's Digital Nautical Chart, used to tell the reader which charts a warning affects.
Distress signal received: A rescue centre has received an alert — from a beacon, a radio call or a satellite terminal — and is asking ships to look.
Position (degrees and minutes): How warnings write positions: degrees, a hyphen, then minutes, with N/S and E/W — 49-40.8N 003-43.8W.
Keep a sharp lookout: A request to every ship in the area to watch for the vessel, people or object described.
Assist if possible: The second half of the standard rescue request: ships able to help are asked to do so.
Inmarsat-C / SafetyNET: The satellite system that carries NAVAREA warnings to ships at sea, and the terminal number rescue centres give for reports.
