25th, 3.(10 The E. horizon much clearer and the luminous glow 

 diminished. A faint curtain crossed the heavens 

 from a point in the N. to somewhat E. of the 

 zenith and trended W.N.W. 



3.15 The luminous haze gradually disappeared. A well- 

 defined auroral hand commencing in the NAY., 

 where previous activity noted, extended across 

 the skv from the old location in the NAY., almost 

 the E.S.E. horizon; trend, W.N.W. The band 

 composed of nebulous streamers, more or less con- 

 nected, in lineal - arrangement. 



3.30 A fine curtain aurora of great brilliancy ran across 

 the sky from the old location in the NAY., almost 

 crossing the zenith, and trending W.N AY. The 

 course Avas somewhat zig-zagged. Streamers fairly 

 well defined. A slow body-travel along its course 

 to the E.S.E. Some time after the main band had 

 formed, auroral nebulae dropped from the curtain 

 below its lower edge. 



3.4o Another parallel curtain now appeared close by to the 

 E. of the brighter one; later on this became looped 

 up with the former in two places. Traces of two 

 other fainter parallel curtains showed only at the 

 N. end. 



4.00 Altogether five parallel curtains have been visible, 

 but have now faded considerably. Several streamers 

 were seen shooting up from the horizon to the S. of 

 Mount Erebus. 



4.15 The curtains brilliantly illuminated half an hour ago 

 were now very faint. Abundant streamers rose in 

 the sky low down between the N. and E. points. 

 These probably originated from two or more 

 parallel arcs. Several streamers bore down on 

 the summit of Mount Erehus and gave the im- 

 pression of being related to it. One streamer 

 appeared over a stratus cloud to the S.E. Careful 

 observations in regard to the manner in which 

 these streamers become illuminated showed that 

 the dull light suddenly kindles up, the luminescence 

 rises upwards as a shaft: other additions are 

 effected below by the luminescence dropping like a 

 slow rocket. 



4.30 The auroral display had almost ceased except in the 

 N. and E., where it was brightening. 



4.4-5 The display concentrated in the N. and E. along the 

 highlands of Ross Island. This Avas mainly in the 

 form of abundant streamers descending to the 

 horizon level. The excitation travelled from the 

 S. to the N. As the streamers waxed and waned 

 the luminescence gradually spread from the 

 streamers until the whole lower heavens in that 

 direction were faintly luminous. 



5.00 Abundant streamers descended on the highlands of 

 Ross Island, immediately N. of Mount Erebus. A 

 single streamer appeared 40° up to the E. 



5.15 A luminous glow appeared on the horizon from N. 

 through E. to K. ; taint streamers were rising from 

 it.
