I have to draw an objection to this. (As an Amateur Astronomer myself).
It's a faulty conclusion as you cannot estimate distance from an objects motion alone, you also need to factor in surface brightness (luminosity) relating to mass/composition, redshift/blueshift (to calculate whether there is motion towards/away from the observer) etc.
Check the following animated gif of two NEO's imaged by an observatory, whilst both are intra-solar, great differences between the motion of the two can be seen. (The image was taken over several hours):http://www.observatorij.org/News/Pictures/49A0112_anim.gif
You still deserve some congratulations though, as my opinion is that you probably observed an extremely hard to view intra-solar object such as an NEO (Near Earth Object) or one of slightly more distance, (But still Intra-Solar).
Checking out the skychart a high contender would be asteroid (40) Harmonia or (27) Euterpe, especially Harmonia, which was very close to the stated positions on Sunday night.
