Hello Drobnock.

Of course you are quite right about the cloud cover.

In my testing however, any pulse or pertabration in the measuring which 
cannot be closely timed to a an acutual photographed meteor event, would be 
useless for valid proof.

I (Must) have visual sighting to accompany the electrostatic measures for it 
to be meaningful. That is why it was shut down during that period.
