We present results from RXTE and EUVE observations of the bright, highly variable Seyfert 1 galaxy, NGC 4051. Spectral analysis of RXTE data obtained from monitoring observations and a 'long look' (,~ 75 ksec) shows: a) strong spectral slope variability in the medium energy X-ray band, b) low energy
