Thank you Nadia!
Very good shot!
All the photos were taken on our last trip to the UK from Australia, in April / May 2008.

That was an unexpected effect due, like you have suggested to a technical problem because of the temperature level as technicians said.
To Skywarrior: Would you please repeat your kyrillic reply in a more readable form (i.e. in English)?
