Notes made by the writer on this occasion record 11.10, red flash (auroral); 11.22, flash resembling an arch of glowing white surmounted by a crest of crimson. The display occurred above a low-lying bank of mist and rose to about five degrees above the horizon. It was not of any considerable breadth, and resembled rather a glow of color against the dark background of the sky than a wide band of light. The moon, which was shining brightly, interfered seriously with the observations of auroral displays which appeared faint in its light. About 12.15 a mist appeared to spread over the city, and the air had become damp and chilly. By 1.30 the mist had cleared away. At 2 o’clock a meteor flashed across the eastern sky, downward in the direction of the star Gamma in the constellation Pegasus. It was bluish-green in color, pear-shaped in appearance, leaving a streak five degrees in length behind it as it flashed to within ten degrees above the horizon. It remained visible for about five seconds, and the display was vivid while it lasted. At 2.30 the moon, low down in the western sky, appeared of a ruddy hue as it “sank in a sea of gloom.” Turning eastward, we saw a soft glow in the sky spreading from below Pegasus and upward as far as the stars of Cassiopeia. At 2.34 a glow of grayish hue extended over the northeastern sky. At 2.43 a bright meteor was seen by Miss L., but she made no note of its direction, except that it was eastward, and a brief glimpse obtained by the writer showed its color as bluish. At 2.45 streamers, which later proved to be the comet, were observed reaching from the eastern horizon, below Gamma Pegasi, and curving upward through Aquarius as far as Altair, and brighter in appearance than the Milky Way. At its widest part, just beneath the first-magnitude star Altair, the width of the band was about ten degrees, and throughout its length it had a brilliancy equal to that of the Milky Way, near which it terminated. The path of this band of light was very nearly that along which the comet was last seen, and the writer was convinced that it was the outer boundary of the tail through which the earth was passing. Beneath this streamer, and apparently resting along the southeastern horizon, was a secondary band resembling a haze-like misty streamer. This was not as clearly defined as was the upper band, and, moreover, it merged into the mists of the horizon. In connection with a sketch made by the writer on this occasion, and shown to Professor Barnard, he referred to it as follows in his account of “Visual Observations of Halley’s Comet in 1910,” published in the _Astrophysical Journal_ for June, 1914:
