You might have seen a ESD (Electro static discharge) of some kind? And that light might have been reflected to your camera at the same time as your hand might have moved, slightly. The older type of digital cameras wasn't that 'fast/sensitive' as I remember it, it took some time for light to register.

If you still have the camera you can test that:)
See how little or much movement disturbs it a cloudy day?

I think you have all solved it for me.. I had to recollect what I did exactly and that is not easy when I took the picture over quite a few years ago! I will try to recreate it as I still have the camera to confirm the theory but I think it goes something like this;

The camera, using the auto focus button was directed at a bright light source to stop the light sensor from disabling the capture. The flash was also charged and flips up out of the camera when in use. Allowing the flash to charge the flap was closed still holding the capture button half way down to hold the focus.
After that the camera was taken outside and directed at the clouds and the capture button pressed fully.
At that point an "electro static discharge" was released from the flash and discharged from the camera and hit my hand.
The reason I thought the light was from the sky was probably that the discharge was within such close proximity to my eye!

The strange lighting effects must be, a combination of a double exposure from the light source and a capture of the electro static discharge.

If any one disagrees please let me know. I only conclude the above based on previous responses to my OP  []

It would be a first if we actually solved a problem. I think it's much more likely your picture is conclusive evidence that we are about to be invaded by extraterrestri.........AAAARRRRGGGGGHHHHH

I wonder if the camera has any value to ghost hunters or ufo hunters so they can forge silly pictures with it!  []

There was a modified Polaroid instant print camera which was used to photograph people's "auras" ...

I think it had coloured lights which fogged the film/print producing the "aura".

They look a bit aurable if you ask me.

Ah, Geezer surely you meant arable?
It do puts it in a cultural setting.

And please my dear man, control your urges, don't get all agri on me now..
We're cultivated here.

Shows us both to be up to the hugest standards of cultivated behavior.
