CONF iture
It would seem that the relevance or otherwise of the 'pollution spot' has not been spotted by the media, or those with a vested interest in keeping the BEA "on its toes".
For the same reasons I expressed in my original post on the subject; the fact that the spots presence could not be explained, should signal further investigation. I have a feeling that Xmas is fast approaching, and the likelihood of not much happening until the New Year, probably sums it up.
