Measurement of the filamentary noctilucent cloud of 2 November 1963 yields a height of 56 km. Study of the motion and orientation of the cloud confirms the hypothesis that these unusual clouds appearing in the southwestern states are produced by the launching of rocket vehicles from the Pacific Missile Range.
