What Are the Solar System Objects in this Image?

On 24 May I made the first set of (what I hope will be) a series of
images of Vesta aimed at showing its retrograde motion against the
fixed stars.

I posted a grayscale composite of red and blue FITS images at
http://www.davidillig.com/ast-vesta070524.shtml.

This set of RGB images has two interlopers. I don't do much Solar
System observing and I have no idea what they are. One object was near
the edge of the field to begin with, and I am ignoring it. The second
object required nearly 28 minutes to traverse approximately 3 deg. 32
min. of arc. I have accurate identities/coordinates for the stars in
the image, but I can't correlate any objects with the time of the
exposures.

Thanks for the help!

Hi Davoud-

Can't say what you caught, but the velocity is just right for the medium
Earth orbit zone around 20,000 km that is used for most navigation
satellites, and some communications satellites. I'd start by checking if
any GPS or Glonass satellites were in the right place.
