It seems that dust cloud was over the North Sea for quite a long time.
These two sat pics from Dundee (NOAA18 AVHRR) show it yesterday and for the
6th May. Back tracking suggests it is of Eurasian origin?

Thanks for the replies, everyone,

This could be one reason why there has been such poor visibility
recently even though the humidity has been relatively low. I am now
beginning to receive other reports of dust falls in NE England over the
past few days. It certainly must have been a big one for me to notice
it!

Best wishes,

Ken
