This was due to the fact that the cloud had to be in sunlight at high altitude, while it  was still dark enough at ground level for the cloud to be visible against the dark sky. In Carter's official 1973 UFO report, as given in the Rhodes book, he stated that he had seen the phenomenon in October, 1969, at 7:15 pm EST. However, it has been determined from Lions Club records that Carter must have seen the 'UFO' when he spoke to their Leary, GA Chapter on January 6, 1969.
