Not illustrated. 1888 Excerpt: ...of colorless auroras, but shows marked disturbance during the vivid displays of color, and sudden, violent changes of form. November 15, 1882 (from 5 a. m. to 12.30 a. m., November 16).--At 5 a. m. faint auroral arch 70 in width was observed extending from E. horizon through Leo Geminorum to northern part of L. 200; also faint streamer from NW. horizon to 150 altitude about io E. of Saturn; color of arch white; streamer occasionally showing red and yellow. At 5.20 a. m. the arch was irregular and broken, shifting gradually north and passing through the zenith. It was somewhat brighter at 5.10 a. m.; streamers showing up along the horizon from NW. to N. with considerable auroral light in all parts of the sky. At 5.35 a. m. two auroral curtains were observed, one extending from N. 750 E. horizon, attaining its maximum altitude loo, about 500 W. of the meridian. There was also considerable light in S. and SE., partly obscured by basin hills. The light quite intense, and was occasionally as bright as a star of first or second magnitude; color white in some parts near horizon, occasional red. At 5.40 a. m. aurora quite faint except in NE. At 5.50 a. m. aurora presents about same appearance as at 5.20 a. m., with the addition of a slight curtain formation in NW. and SE. At 6 a. m. the auroral light above Hall Basin was quite intense, and at 6.25 a. m. faint streamers shooting up from all points of the horizon. At 6.35 a. m. arch quite bright was observed extending from N. 950 E. to NE. 3150 E., passing about loo N. of zenith. At 6.45 a. m. the arch was very bright, especially at the zenith, where it was about 200 in width and of intense white. The streamers had all disappeared. At 7 a. m. the whole northern sky was filled with streamers, extending about 150 beyon...
