We present a determination of the effective temperatures, iron abundances and microturbulent velocities for the pseudo-photosphere of V838 Mon on 2002 February 25, and March 2 and 26. Physical parameters of the line-forming region were obtained in the framework of a self-consistent approach, using fits of synthetic spectra to observed spectra in the wavelength range 5500-6700 Å. We obtained T_eff= 5330±300, 5540±270 and 4960±190 K, for February 25, March 2, and March 26, respectively. The iron abundance logN(Fe) =-4.7 does not appear to change in the atmosphere of V838 Mon from 2002 February 25 to March 26.
