JPL#56 (23-01-08) : 15b1cab2-e386-4338-be9d-83ff0bafd1f1 [db: observed]

Using prediction 15b1cab2-e386-4338-be9d-83ff0bafd1f1 for map and profile fit

Ellipse and circular profile fits to the timings (chords)

 Auto-Fit Result:
Size = 199 x 28 km
a',b' = 99.7, 13.9 km
X0,Y0 = -318.9, 45.5 km
Mean diameter = 74 km

From 4 chords (VIS)








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.
