25th, point due W. of the zenith. This display in the 



S.S.W. sprung from the top of a fairly dense 

 stratus or alto-stratus cloud. 



11.30 The first-mentioned curtain had now developed into 

 a brilliant luminous arc crossing the whole sky 

 extending S. from the zenith to a bank of stratus 

 cloud in the S., then bending sharply to the W. 

 At the same time the auroral glow from the 

 S.S.W. had spread N. to a point about due W. of 

 the zenith, the arc terminating 30° to 35° above 

 the horizon. 



11.35 A few minutes later, about 11.35 a.m., the main 

 curtain aurora broke up in the S. to five immense 

 beams. Meanwhile both this aurora and the one 

 originating in the S.S.W. were very distinctly 

 coloured with a siskin-green to pale peacock-green 

 tint. Excitation appeared to travel from the N. 

 to S. 



11.45 Auroral glow over stratus cloud to S. of Mount 

 Erebus. 



12.45 Slight auroral glow on the same cloud, the top of 

 which was about 12° above the S.E, horizon. A 

 remarkablv sudden appearance of cirrus clouds to 

 the W.N.W. and W. 



13.30 A faint bent curtain extended from the E.S.E. to 

 the N.W. passing over the zenith, where it was seen 

 to trend W.N.W. A long but faint auroral 

 streamer, trending W.N.W., appeared just at the 

 spot where the remarkable cirrus clouds were noted 

 # previously, the clouds in the meantime having now 

 almost disappeared. At the same time the glow 

 over stratus to the S.S.W. occasionally assumed a 

 curtain structure. 



14.00 A fairly bright curtain aurora, extended from the 

 E. by S. to the S. of Mount Erebus, trending in a 

 W. by N. direction, but bending to the N.W. 

 after reaching the vicinity of the zenith. 



14.40 A moderately bright auroral arc extended from the 

 S.E. beyond Cape Barne across the zenith to the 

 N.W. 



15.00 Three auroral arcs springing from a bank of stratus 

 clouds from the E.S.E. horizon, between Cape 

 Barne and Mount Erebus. The two westerly mem- 

 bers were joined together at an elevation of 33° 

 above the horizon. The more easterly arc extended 

 across the zenith, trending to the N.W. by W. The 

 excitation came from the E.S.E. 



15.10 The three curtains have now more or less coalesced. 

 They have distinctly travelled N. The main cur- 

 tain, now springing from the true E. horizon, 

 bent around Mount Erebus, crossed the zenith, and 

 extended to the W. horizon between N.W. by W. 

 and W.N.W. There was a general drift to the N. 



16.00 Tavo auroral arcs extended from about E. by S. on 

 the S. flank of Mount Erebus, up to the zenith, 

 then extending to the W. by N., and finally W.
