About 1440 today 14 March 2009. Predominant cumulus but les than 50 % -
perhaps 30-40%. To the north - towards or over or perhaps beyond London,
marked vertical development - near vertical striations, not straight, in
a gentle s-curve.

Feature now replaced by amorphous high cloud with marked cumulus-tyoe
top in that direction by 1450.
