Robin, the short time you saw the object restricts the interpretation
to ameteor, a slow one at that. meteors come at all angles including 
S to N, horizontal to vertically downward.
A re-entry object following such a trajectory as you describe
would be visible for 30-50 seconds. Any re-entering satellite 
is essentially travelling horizontally at 7.2km/s ( slow for meteors)
at about 100Km above the surface of the earth. meteors are much more
common occurence than satellite re-entries.
