Abstract
ON Sunday evening 4th inst, a beautiful display of aurora was observed here (lat. 51° 26′ 0″ N., long. 0° 20′ 53″ W.). My attention was first directed to it at 6h. 4m. (G. M. T.) at which time there was a fiery glow over a considerable portion of the southern sky, much resembling the reflection of a distant conflagration. Shortly after, an almost complete auroral arch, of faint orange red light, similar to that at first observed, was noticed, extending from E., above and partly embracing δ, ɛ, and ζ Ononis, to W., its altitude (by estimation) at the centre being about 40°, and its extent something like 120°. For a short time this glow was most intense in S.S.E. at a great altitude, but the display attained its greatest intensity about 6h. 15m., when a number of rays or streamers of whitish blue and orange red light appeared as if radiating from a point near δ, α, and κ Persei. At 6h. 20m. nothing was observed but a widely diffused fiery glow, which must have continued more or less during the whole evening, as it was again observed by me at 8h. 25m.
