Abstract
As none of your correspondents who described the brilliant auroræ of Nov. 9th and 10th last week, speak of their being seen earlier than from 7 to 10 P.M., it may be interesting to note that in the Midland Counties the latter was visible at a considerably earlier period of the evening. On the evening of the 10th I was walking from Reading in Berkshire to Caversham in Oxfordshire, from 5.45 to 6.5 P.M. During the whole of that time I had before me the steady white light of the coming aurora, extending perhaps 25° to 30° in width, and 20° in height, its centre being immediately beneath Polaris. The appearance was exactly that of the departing twilight in a clear winter sky, for which, indeed, but for its position and the time of the evening, it would have been mistaken. As I noticed the light immediately on leaving the railway station above the lights of the town, I have little doubt that it had been visible since sunset. I had no opportunity of watching its progress after 6.5 P.M.; up to that time there were no coloured streamers, nothing but the white light I have described.
