Hello List,

Sikhote Alin should also be on this list:

BUCHWALD V.F. (1975) Iron Meteorites (Univ.
of California, 1975, Vol.1 , p. 18 / Vol. 3, p. 1126):

Date of fall: Feb 12, 1947

Time: 10.38 a.m. (local time)

Direction: N -> S (10-15° east of north)

Initial inclination: 41°

The initial declination had increased to 60-70°
at the time of impact (zenith angle about 49°).

Apparent diameter of the bolide: 600m
(with its luminous envelope).

Length of smoke trail: 33 ± 9 km

Dust trail observed for several hours.

Brightness of bolide: exceeded that of the sun (about - 26)

Point of complete breakup: 4 - 6 km (Hemmungspunkt)

Initial velocity: 14.5 km/s

Geocentric velocity: 9.2 km/s

Heliocentric velocity: 37 km/s

Final velocities: 0.1 - 1 km/s

Elements of the asteroidal orbit:

Semimajor axis a = 2.162 a.u.
q = 0.99 a.u.
Q = 3.34 a.u.
e = 0.544
w = 181° 15'
i = 9° 25'
Length of ascending node = 322° 28'
