Information Gathering Satellite - an optical imaging reconnaissance satellite launched as a replacement for IGS 3 (IGS Optical 2) - 2006-037A/29393, which was nearing the end of its life. Precise time - 04:36:03 UTC, at the opening of a 14 minute window. Element sets are not released by Spacetrack so parameters are based on amateur observation.
