The arc has remained perfectly regular; its two ends almost touch the horizon, and they advance to the east and to the west, widening the distance between them and showing more and more the contour of a circle as the bow of light rises."
For the first hour no beams were discernible, but the whole display consisted of an almost uniform light of a delightfully soft, cream color.
