Hey Folks!

I got a question! I live in southern Brazil, declination 27. As I was
driving to work, I looked at the sky and I saw an object of aparent
magnitude of 3 bouncing to 2, it was no star , for it was 7:55am,
which in this season, is broad daylight already, and its magnitude
kept changing, I believe, because of its movement that reflect the sun
differently.

The object was moving quite fast at my zenith towards northwest, when
I called my wife's atention to look at it, it was gone.

The thing is, I've seen quite a few satelites already, and they move
waaaay too fast, this object too almost 20 seconds to disapear from my
sight.

My question is, is it possible to see our satelites or the ISS on
broad day light? If not, what exactly would that be?
