Abstract
ON the night of the 25th a most gorgeous aurora borealis was visible at North Shields. I first observed it about 6 P.M., when it formed a splendid boreal crown, of which the centre was about 25° south-east of the zenith. Rays of brilliant crimson converged to it from all directions, especially from N.E., S., and S.W. To the north the light was more of the ordinary colour. They appeared to rise from an irregular circle, extending round the whole horizon, and slightly arched in the N. W. Below this was the usual dusky cloud. When the rays, or rather sheets, of crimson were at their brightest, they were streaked with yellowish light. At times the centre of convergence was dark, at others it was occupied by luminous clouds of twisted forms, reminding me of those of some of the nebulæ. The rays seemed to have a slow motion towards the south.
