Note 8 — Chapter VIII · Second Autumn in the Ice

“There was a lovely aurora borealis at 8 o’clock this evening. It wound itself like a fiery serpent in a double coil across the sky. The tail was about 10° above the horizon in the north. Thence it turned off with many windings in an easterly direction, then round again, and westward in the form of an arch from 30° to 40° above the horizon, sinking down again to the west and rolling itself up into a ball, from which several branches spread out over the sky. The arches were in active motion, while pencils of streamers shot out swiftly from the west towards the east, and the whole serpent kept incessantly undulating into fresh curves. Gradually it mounted up over the sky nearly to the zenith, while at the same time the uppermost bend or arch separated into several fainter undulations, the ball in the northeast glowed intensely, and brilliant streamers shot upwards to the zenith from several places in the arches, especially from the ball and from the bend farthest away in the northeast. The illumination was now at its highest, the color being principally a strong yellow, though at some spots it verged towards a yellowish red, while at other places it was a greenish white. When the upper wave reached the zenith the phenomenon lost something of its brilliancy, dispersing little by little, leaving merely a faint indication of an aurora in the southern sky. On coming up again on deck later in the evening, I found nearly the whole of the aurora collected in the southern half of the sky. A low arch, 5° in height, could be seen far down in the south over the dark segment of the horizon. Between this and the zenith were four other vague, wavy arches, the topmost of which passed right across it; here and there vivid streamers shot flaming upward, especially from the undermost arch in the south. No arch was to be seen in the northern part of the sky, only streamers every here and there. To-night, as usual, there are traces of aurora to be seen over the whole sky; light mists or streamers are often plainly visible, and the sky seems to be constantly covered with a luminous veil,8 in which every here and there are dark holes.
