I (arbitrarily) limited ranges to 4500-55555 km ; do you have an estimate of its angular velocity (or time to cross your (7 deg 7*50?) field-of-view. Also, the apparent motion angle (left) - is that "exactly" DIR=270 degrees or what? A close encounter is 24799 DFH-3 Long March r at 58.5/150 02:31:30, using SkyMap SGP4, satbase.tle and: DFH-3 Long March r 18242 x 194 km 1 24799U 97021B 02188.48544066 .00051606 -62830-6 12201-2 0 1844 2 24799 29.0082 189.8063 5785765 339.1713 4.5927 4.45755836 56802 (within elset error margin - I should get a newer elset). It's local motion was to DIR=260 deg, range 4582 km.
