how can it be an irridium flare when such a flare has a megnitude of -8 and
on the original photo i don't see the "flare" but when i change the levels
of the photo so that i see things with a higher magnitude it gets visible...
So the thing i saw was something with a high magnitude and a irridium flaire
has a very low magnitude

"it just kept streaking downward andeventually appeared to break into
several pieces before going behind the tree line."

It was, probably, a bolide. A bolide is a bright meteor that breaks up
as it enters the atmosphere.

It's certainly not a meteor.


Why do you say that? I've got dozens of images with meteors that look just like
that.


I've never seen a meteor trace out a line of uniform brightness and
thickness on any exposure.

I've seen such meteors quite often. As long as the particle is too small to
fragment, the path is often of uniform brightness. I have some film images made
during Leonid showers showing two or three bright meteors with varying
brightness, and several more very dim ones that look like scratches on the film,
very uniform.

The maximum magnitude of an Iridium flare is -8, but unless you are in
exactly the right position you won't get a mag -8 flare. Look at
www.heavens-above.com and you'll see that for a given time period and
lat/long. you will have flares between -1 and -8.
