Met.Bull. 85, 2001 Sep., in MAPS 36-9, A298:

After a bright fireball was observed in the Czech Republic, Poland,
and Slovakia, and a sonic boom was heard in northern Moravia, a 214
gr stone that had passed through a spruce tree and landed in a garden
was collected. Two other pieces weighing 329 gr and 90 gr were
collected later in May and in June. The fall was videotaped, allowing
the calculation of orbital parameters (P.Spurný, J. Borovicka,
Z.Ceplecha, CAS):

a = 1.95 ± 0.11 AU, e = 0.50 ± 0.03, q = 0.9833 ± 0.0011 AU, Q =
2.92 ± 0.23 AU, W = 46.2580° ± 0.0001, i = 33.0° ± 0.7.

BOROVICKA J. et al. (2001) The Morávka meteorite fall:
Fireball trajectory orbit and fragmentation from video records
(MAPS 36-9, 2001, A025): => refined orbital data

Morávka, H5
Density: 3.59 ± 0.05 g/cm^3

Observations:

- visual sightings
- video recordings
=> extensive fragmentation and deceleration

- satellite
- seismic stations
- sonic booms and infrasounds

Orbital data measured:

Entry velocity: 22.5 ± 0.5 km/s
Azimuth: 175.5 ± 0.5° / slope: 20.4 ± 0.2°
End height of luminous path: 21.2 km
(deceleration has reached: 3.7 km/s)
Preatmospheric mass: ca. 2000 kg
Preatmospheric diameter: 1 meter

Orbital elements:

i = 32.2 ± 0.8°
a = 1.85 ± 0.05 AU
e = 0.47 ± 0.03
q = 0.9823 ± 0.0012 AU
Q = 2.7 ± 0.2 AU
w = 203.5 ± 1.0°
L. ascend. node = 46.2580°


Best Sunday wishes,
