I just had a quick look at the paper by Popova, Meteoroid Ablation
models (2004) Earth, Moon, and Planets, vol. 95, 303-319, and their
spectral data from meteorites indicate that the brightness
temperatures of the vapor are around 4000-6000K.

At least the melting point of iron, which is 2800*F.

Eric,
A quick check of O. Richard Norton's Rocks from Space puts it >3000
