:25th, 00.45 Generally the same. Three auroral streamers rose 

 above the luminous edge of the horizon cloud-bank 

 to the S.E. The luminous haze on the N. slope of 

 Mount Erebus sensibly brighter. A first-magnitude 

 star could be seen faintly through the lower dark 

 horizon-haze to the S.S.E. 



1.00 The haze dispersed slowly. A gloAV observable 

 ' located at a spot close by the N. slopes of Mount 

 Erebus; this was unusually bright of its kind, and 

 waxes and wanes. A couple of broad nebulous 

 streamers rose from the N.W. to the N.N.W. 

 horizon ; these became visible at intervals. A cur- 

 tain trending N. by W. crossed the sky, com- 

 mencing just S. of the zenith and terminating 

 immediately W. of Cape Bird ; this was very faint 

 and properly observable only after the eyes have 

 accommodated themselves to the outer darkness. 

 Under these conditions even the streamers appeared 

 nebulous, ill-defined, and were separated from each 

 other by broad dark spaces. 



1.15 A luminous border was well developed both above 

 and below a cloud-bank extending from the summit 

 of Mount Erebus to the S.E. A couple of faint 

 curtains trended N.N.W. (like that just noted), 

 extending from the N. horizon to the zenith. The 

 more westerly was much the stronger. 



1.30 From the spot on the N. horizon which had appeared 

 luminous, a hazy but bright curtain now rose up 

 to the zenith. This slowly faded in about five 

 minutes, but, later, revivified, excitation coming 

 from the N. Trend generally N.N.W., with minor 

 bends. The streamers were not defined ; a definite 

 slow di'ift observed to the S. 



1.45 The luminous border on the cloud-bank to the S. was 

 stronger ; the same was also very noticeable around 

 a large cloud extending in a N. and S. direction 

 from the top of Mount Erebus. Bright nebulous 

 patches appeared in the sky to the N.W. about 

 15° up ; this Avas slightly W. of the position of the 

 former curtain. 



2.00 The luminous border on the clouds above referred to 

 became stronger. In the S.E. faint streamers rose 

 above the cloud. 



12.15 Generally the. same, though somewhat brighter. 

 Horizon-haze almost cleared awav, especiallv from 

 N.W. through W." to S. 



.2. 30 Luminous glow on the horizon to the N. of Mount 

 Erebus was strong. A faint streamer was noted 

 descending into a stratus cloud 20° up in the sky 

 to the S'.E. 



3A5 Small dark clouds to the E. floated in a luminous 

 haze extending to a height of 25° above the 

 horizon. Faint auroral brushes appeared rising 

 above this belt in an E.N.E. direction. An 

 auroral blush iappeared on the horizon to the N.W. 

 in the location where the earlier demonstration 

 appeared.
