I was disappointed with

http://www.metoffice.gov.uk/weather/...o/iceland.html

where they do appear to have recent images
but despite the statement "Please refer to the forecaster blog to read
the latest information regarding the evolution of the plume."
the forecaster blog was last updated on 30th May 2010.

Well I suppose it is the weekend - but Don's questions could do with
an answer !
