The cloud was very unusual and puzzled scientists at the time, who could not find a conclusive explanation for the cloud.  The height of the cloud was initially estimated by James E. McDonald from the Institute of Atmospheric Physics at the University of Arizona, Tucson, as being approximately 35 kilometers but was later revised by him to be at approximately 43 kilometers (141,000 feet).
