A blue triangle hovered near a facility

This is email correspondence approving an unclassified review of a civilian's nighttime report of a large blue triangular object hovering near a national security facility in the Pacific time zone in March 2023. Most of the file is review and approval traffic rather than the sighting itself. The location near a sensitive site is interesting, but the public text does not establish what the object actually was.
