Plantifreeze Mk ll

I had spotted this phenomenon many a time and oft B4, but not really timed it.
This time I can state, categorically, that (disregarding seconds)
The left hand side was taken @ 09:19
The rt.  hand  side was taken @ 10:02.
Last one was about same time last year. If I'd known as much then I'd have lightened LHS a wee bit more. (13-03-18, I do now, so I have.)
