Ttli. whole of the summit of the mountain was capped 



by a brush of streamers rising to a height of about 

 •5°. This brush became very bright, and at this 

 time no smoke could be seen rising from the crater. 

 A few minutes later it waned, and as it did so a 

 column of smoke became visible between us and 

 the luminous glow. During this time a bright 

 glow occasionally appeared over the crater. This 

 evidence appears to definitely relate the auroral 

 brush to a close proximity with the summit of the 

 mountain . 



15.00 The aurora still continued. 



16. HO | Auroral streamers and a low nebulous were visible to 



17.45/ the S.E. and E., passing from the horizon behind 

 Cape Barne to the E. of Mount Erebus. 



17.50 Practically no laurora now visible. 



18.00 Auroral glow and streamers on horizon to the N. of 

 Mount Erebus. 



22.00 A distinct auroral glow observed on a stratus cloud 

 15° up to the S. by E. A faint curtain 40° up 

 extending from E. to N. (moonlight obscured faint 

 effects). 



22.30 About four brilliant parallel curtains, situated to the 

 E. of the zenith, trending N. and S. ; slight body- 

 drift to the N. 



23.00 The outlines of the previously-observed curtains were 

 now but" roughly indicated by the distribution of 

 isolated nebulous blobs. Only the very slightest 

 body movement to the N. The night was unusually 

 calm and the aurora steady. 



23.30- About six parallel curtains extended over the whole 

 sky, excepting between the S.W. and W.N.W. 

 They trended in a general N. and S. direction, 

 but were bowed convex to the W. They exhibited 

 a slow body-drift to the N. 



24.00 There were three parallel curtains in the E. sky 

 similar to those just referred to. That nearest the 

 zenith was 70° above the horizon. The others 

 were lower down, and met the horizon betAveen 

 X.E. and S.S.W. The trend appeared to be still 

 N. and S. 

 3th, 00.30 An auroral curtain crossed the sky near the zenith 

 about 80° above the E. horizon. For the most part 

 this trended N. and S., but was bowed, with a 

 slight convexity to the W. The luminosity was 

 greatest in the N. A fragment of another curtain 

 was visible 15° up in the S.E. 

 1.00 Faint streamers rising above the Ross Tsland high- 

 lands between N. and S.E. 

 1.30 Very faint streamers rising high up above Ross 

 .Island highlands. A luminous haze developed in 

 the vicinity of the horizon. Careful observation 

 showed that this haze passed above into faint 

 streamers, rising as much as 12° above the horizon. 

 2.00 A fairly well-defined curtain extended to the S. from 

 just E. of the zenith; trend, N. and S. ; slow 

 body-travel to the N.
