Helicopter with light ver.2

If the lighted ball/orb following this helicopter was a snowflake, it's a big one. For snow ( it was not snowing that Sept. day ) to only be seen clearly by zooming in on the picture means that it was not close to the lens and if not then it must be quite large. The rescue helo. is not exactly small and was perhaps a little under a quarter mile away ( I was using the zoom but not above 2.5x optical ) and at an altitude of under 1000ft.. It appeared to be to the right and a little behind the helo.. Did they know it was there? I'm not sure, they flew by at a steady speed with no deviation in heading.
I have 5 photos of the helicopter as it passed by, 4 with the object in them which represents aprox. 45 seconds in time. While I don't remember it being a windy day if it was a balloon then the wash of the helicopter over that time would have moved it quite far away in one direction or another, would it not?
I'd put it at the size of one of those orbs seen moving in the cropcircle footage. These things are rather common and seem to move in a controlled manner. Maybe some footage using a hi def camcorder would help clear up the images. Donations welcome, LOL.
