Abstract
Early results from the 70µm observations of the Spitzer Extragalactic First Look Survey are presented. As a whole, about 90% of the population show infrared colors that are consistent with the spectral energy distributions of the
local IRAS population of luminous infrared starbursts, while approximately 10% of the sample show warm infrared colors consistent with AGN activity. The mean redshift for the population is z = 0.2, and the mean total infrared luminosity is about L(ir) = 2 x 10^(11)L_⊙
