The Aurora of March 4

Abstract

THE fine auroral display, noticed in NATURE, March 12, pp. 437 and 444, was brilliantly visible from the streets of Dublin at 8 p.m. on March 4. The great beam, rising from the characteristic bank of cloud into a starry sky, originated due west, and, if continued, would have passed to the south of the zenith. At 8.5 three or four short parallel rays, resembling a gridiron, appeared in a patchy way some 20° to the north, in a similarly clear sky; they disappeared rapidly, and five similar parallel bars arose close to the north side of the main ray at 8.10. At 9.30 the display had faded, as far as the city was concerned.
