Strange darkness and eerie red light over Cuckfield this afternoon at 15.00hr

 There was a strange darkness and eerie red light over Cuckfield this afternoon at 15.00hr.  Sunset is not due untill 18.07hr.  It is like night already now.  Click on any picture to enlarge it.

It was so dark that with a fast ISO3200 camera setting and F8.0, the shutter speed was a slow 1/25 second pointing directly at the sky.  The street lights came on but were off at 15.40hr.

Then at 16.12hr above, it was daylight again with a cloudy grey sky after a very strange experience.
