Quick MET question
Saw this in the TTF for YSSY tonight;
I'm clear on the meaning of all of that except for 6AC140 - can anyone shed light on it for me?

cant help you with the BV and IT. Does it say anything in AIP?? //// doesn't necessarily mean visibility, only when it's in the spot reserved for vis. The slashes mean are that they don't have the data for that particular item of your metar. (Admittedly most commonly vis. at places with an auto met station for example)

Once asked the same question to BoM. Apparently is maintenance/technical data sent via the same telemetry as the weather info. BV is the battery voltage of the backup battery and IT is the internal temperature. Sometimes gets broadcast as part of METAR or TTF in error.
