The soft x-ray spectra of heavy element plasmas are frequently dominated by unre- solved transition array (UTA) emission. We describe the spectral evolution of an intense UTA under optically thin conditions in platinum plasmas. The UTA was observed to have a peak wavelength around 4.6 nm at line-of-sight averaged elec- tron temperatures less than 1.4 keV at electron densities of (2.5–7.5) × 1013 cm
