Abstract. This Meteoritical Bulletin lists 53 meteorites, of which 16
are from the Nullarbor, Australia, and 12 from Roosevelt County,
New Mexico. Besides ordinary chondrites, there are five irons and one
howardite (Mundrabilla 018). Four of the meteorites are falls
(Baszkówka, Campos Salos, Neagari,
and New Halfa).
Aachen
50d46.5'N, 6d05'E
- Nordrhein-Westfalen, Germany
- Date of fall or find unknown
- Ordinary chondrite (L5, S3)
A stony meteorite (weight 21 g, partly covered by fusion crust)
labeled "Meteorite, fell near Aachen" is on display in the
Lippesches Landesmuseum, Detmold. No further circumstances of
find or fall are known. A comparison of the handwriting on the
label with other labels suggests that the meteorite came into the
museum collection around 1880. Classification and analysis:
olivine Fa24.6,; pyroxene Fs20.5; M, Schliestedt, Institute of
Mineralogy, University of Hannover, D-30167 Hannover, Germany,
and R. Bartoschewitz, Lehmweg 53, D-38518 Gifhorn, Germany.
Information; R. Bartoschewitz.
Baszkówka
52d02.00'N, 20d56.15'E
- Warszawa, Poland
- Fell 1994 August 25, 15:50 local time
- Ordinary chondrite (L5)
The fall was observed by Halina Grodzki in the village Baszkówka,
23 km SSW of Warszawa. A moment before she heard a sonic
boom, she saw a movement on the surface of cultivated land, -200
m away from her. Krzysztof Grodzki located a circular area of fresh
ground ~2 m wide and recovered the stone from 25 cm under the
surface. It is an oriented stone of 15.5 kg with radial regmaglypts
on the "Brustseite" (Fig. 1). Classification and analysis: olivine
Fa24.2; pyroxene Fs20.8; Frank Wlotzka, Max-Planck-Institut fur
Chemie, D-55122 Mainz, Germany, and Marian Stepniewski and
Jerzy Borucki, National Geological Institute, ul. Rakowiecka 4, 00-
975 Warszawa, Poland, where the main mass is also located.
Information: Marian Stepniewski. See also Stepniewski (1995).

- Fayette County, Texas, USA
- Found 1878 to 1917
- Ordinary chondrites
A study of meteorites from Fayette County, Texas (McCoy et al.,
1995b), showed that the three Bluff stones listed in Graham et al.
(1985) represent two distinct falls. Details are listed in Table l.

Campos Sales
7d02'S, 40d10'W
- Ceará, Brazil
- Fell 1991 January 31, 22:00 local time
- Ordinary chondrite (L5)
A meteorite shower fell in a rural area ~18 km E of the village
Campos Sales. W. Vieira, T. V. Costa and J. N. Neto arrived 15
days later and recovered a total of 23.68 kg of stones from
grainfields along a road. They collected 35 large specimens,
ranging from 3 g to 3.5 kg (total = 21.3 kg), and ~300 fragments,
spread over a distance of -3 km. According to local eyewitnesses,
the shower came from a WSW direction (70deg against N).

Siwa
28d30'N, 25d30'E
- Egypt
- Found 1994 April 14
- Ordinary chondrite (L5-6)
Two stones, ~23 and 13 g, were found together on the sand, ~20 km south
of the oasis Siwa. They were found by Dr. Romano Serra during a field
trip organized and supported by the Centro Studi "Luigi Nero," Corno,
Italy, with the scientific collaboration of the Natural History Museum,
Milano, Italy, and with permission of the Egyptian Geological Survey and
Mining Authority, Cairo, Egypt. Ron Farrell, Bethany Sciences, New
Haven, Connecticut, USA, recognized the stones as meteorites.

Travis County (a) and (b)
30d33'20'?4, 97d57'10"W
- Texas, USA
- Found 1889 -- 1962
- Ordinary chondrites
A detailed study of 52 meteorites recovered from Travis County was
undertaken by McCoy et al. (1995a). They found two distinct
meteorites: Travis County (a), a H5(S4)W3 shock blackened chondrite,
represented by 41 specimens with a total weight of 175.4 kg; and Travis
County (b), a H4(S2)W3 chondrite with rare chonditic clasts of H group
parentage, represented by 11 specimens with a total mass of 5.9 kg. The
samples are in the Oscar Monnig Collection, Texas Christian University,
Fort Worth, Texas. The original Travis County
meteorite, found in 1889, listed in Graham et al. (1985) belongs to
Travis County (a). Classification and analysis: Travis County (a) =
olivine Fa16.2-16.9; orthopyroxene Fs15.3-15.8; Wo1.0-1.1; Travis County
(b) = olivine Fa16.6-18.9; ortho-pyroxene Fs16.0-16.3; Wo1.1-1.2; Timothy

Geosciences Division, Department of Geology and Geophysics,

One stone of about 150 g was found by T. Davis in Udall Park, a
park area in a desert scrub terrane within the city limits of Tucson.
Classification, analysis (olivine Fa18.3; pyroxene Fs16.6), type
specimen and information: David A. Kring, Lunar and Planetary
Laboratory, University of Arizona, Tucson, Arizona 85721, USA.
The main mass (142 g) is with Robert Haag, P. O. Box 27527,
