Ellipse and circular profile fits to the timings (chords)

 Auto-Fit Result:
X0,Y0 = -845.8, 81.3 km
Circular diameter = 152 km

From 2 chords (VID)








You can enter space separated chord numbers (example: 11 4 8) or a method like VIS to ignore all visual timings, or a time source like RAD and NTP (but not GPS).
If the plot disappears, then there are less than 2 chords left (too much ignored, go back with browser).

Check SiMDA for size and mass data.

Check Johnston Archive for satellites.
