This launch was taken before I got my polarizer, so this is the last launch with a huge ball of light. Below is a discription of the Delta 4 from spaceflightnow.com The United Launch Alliance Delta 4 rocket launched the third Wideband Global SATCOM spacecraft, formerly known as the Wideband Gapfiller Satellite. Built by Boeing, this geostationary communications spacecraft will serve US military forces. The rocket flew in the Medium+ (5,4) configuration with four solid rocket boosters.
