(meteorobs) Wonderful turquoise fireball ! - New Mexico

[Bill Cooke]

Have a decent solution on this event:

Start point: 107.52 W, 33.10 N at an altitude of 97.6 km
End point: 108.21 W, 33.77 N at an altitude of 82.4 km
Speed: 26.1 km/s
Radiant coordinates:  RA 91.392 +/-  0.07 deg, Dec -32.753 +/-  0.04 deg 

Note: end point is where the meteor exited Mayhill camera FoV - not actual ablation height of the meteor.

Mass (lower bound): 200.0 grams
Diameter (assuming density of 2.5 g per cc): 5.3 cm

Orbital parameters:

a - 2.851 +/-  0.2 AU  
e - 0.693 +/-  0.02     
incl - 33.4 +/-  0.4 deg 
omega - 43.2 +/-  0.4 deg 
asc_node  99.9 +/-  0.0 deg 

Orbit plot - this meteor is the one in orange, with an aphelion near the orbit of Jupiter.
