Day Auroras

Abstract

LAST evening, about eight o'clock, being in the grounds belonging to the Radcliffe Observatory, I was exceedingly surprised at seeing what I have no doubt of being true auroral streamers, forming a little to the east of the south meridian, reaching an altitude of about 25°, and after travelling some distance in a westerly direction, vanishing. This lasted at least ten minutes, when the sky, which had been overcast nearly all day again became so. I pointed the streamers out to several people who were near me, some of whom watched them with me, as a proof of what I had before doubted, namely, that auroras are visible by daylight.
