Let me think here. Geostationary satellite?
In 2 minutes, it moves 2 minutes to the left.
In 1440 minutes (24hr), it moves 1400 minutes (24 hrs) to the left.
So it orbits the earth every 24 hours.
It is above the equator, where geostationary satellites are placed. Could be.
But usually see more than one, since they appear in groups.
EDIT
The track wobbles. A tumbling rocket stage might wobble as it rotates end over end,
