This new meteorite fell to Earth on December 16, 2012.  At least 50-60 stones were recovered, with a total known weight of approximately 6 kilograms.  The meteorite appears to be an equilibrated L-chondrite, with stunning, pristine fusion crust and a brecciated interior.  

The strewn-field is close to the Morocco-Mauritania or Morocco-Algeria border, near a town called Mheiriz (or Mehaires, depending on which map you use).  Mheiriz is in Eastern Morocco, near Smara.

Different stones from this fall have been classified as both L4 and L6.  It appears to be a brecciated impact melt, with many stones exhibiting large (>1cm) patches and veins of black, melted chondritic material.  I would assume that the meteorite will be classified as an L4-6 breccia, but it is hard to tell whether the official classification will reflect the full range of material within this meteorite. 

The meteorite has been formally approved as two separate meteorites: NWA 7827 (L4), and Mreïra (L6).  Unfortunately, short-lived radionuclides from these stones were not examined, so although many of the stones show no evidence for weathering and exhibit impact scars, the fall date was not analytically constrained and the meteorite has been approved as "a possible fall associated with the fireball of December 16, 2012."

Amazingly textured crust with fine froth and iridiscent blue spots.  One side shows scuffing caused by an impact with rocky ground. 
The larger chip has reddened at the edges due to exposure to heat; it was a late atmospheric break.
