History and physical characteristics: (G. Raade and K. Ødegaard, UOslo; M. Bilet, NorAS) At about 10:20 am on July 14, 2006, a bright fireball traveling SSE-NNW was witnessed by many people and a loud explosion and a rumbling sound was heard in the air above Moss and Rygge in south Norway, on the east side of the Oslofjord. Shortly after, a small meteorite was heard to land on an aluminum sheet and was recovered. Extensive searches in the area have resulted in the recovery of a total of 5 stones (Table 6). Note that light rainfall occurred in the area on July 29, 30, and 31. Petrography: (J. Grossman, USGS; G. MacPherson, SI; L. Chizmadia, UHaw; A. Rubin, UCLA): Contains abundant small chondrules (most < 200 μm), small (

History: The meteorite was purchased from a local meteorite dealer in Algeria. Physical characteristics: Brownish fragment without fusion crust. Petrography: The meteorite shows a dark brownish to black interior and is composed of abundant small chondrules, CAIs, and mineral fragments set into a fine-grained matrix. Chondrules are dominantly porphyritic type I with a mean diameter of about 0.2 mm. Some sulfides and FeNi metal are present in matrix and chondrules.

History: The meteorite was purchased from a meteorite dealer in Morocco. Physical characteristics: Brownish rock without fusion crust. Petrography: The meteorite shows a dark brownish to reddish interior and is predominantly composed of abundant small chondrules, CAIs, and mineral fragments set into an abundant fine-grained matrix. Chondrules have a mean diameter of about 0.2 mm. Few chondrules are surrounded by fine-grained rims. Opaque phases are partly altered metal and troilite.
