OT: a multistation filmed meteor from 27 March - some results on the trajectory
The movie above shows the meteor footage as obtained from Leiden and Hengelo, plus a 360-degree fly-by around the reconstructed atmospheric trajectory.
The meteor started at 51.745 N, 6.267 E, at 100.4 km altitude. It ended at 51.961 N, 6.707 E and 75.2 km altitude. It had an initial velocity of 27.8 km/s.
Above are two integrated frames images of the meteor, a still image showing the 3D trajectory, and images showing the orbit in the solar system. As the convergence angle between the trails as seen from both video stations was not particularly large, the resulting orbit has some inaccuracy. Nominal orbital element values are:
a = 1.87 AU,
q = 0.450 AU,
e = 0.759,
i = 10.47 deg,
omega = 285.84 deg,
node = 6.696 deg.
The geocentric radiant was near RA 198.20 deg, dec. +4.01 deg, Vgeo 25.67 km/s. The radiant position has some leeway due to the low convergence angle. Hengelo saw the meteor appear in Corona Borealis: Leiden in the Aquila-Sagitta-Delphinus border area.
