22nd. associated with a luminous haze, hung above the 



highlands to the N.N.E. 



22.00 A long nebulous curtain, commencing just N. of 

 Mount Erebus, extended far to the W., trending 

 in a S.W. direction. 



23.00 A nebulous auroral display over Mount Erebus. 



24.00 A streamer 30° up in the X., and several dull patches 

 near the horizon between E. and S.E. The dis- 

 play this evening was generally similar to that of 

 the preceding evening, only less bright. 

 23rd, 00.30 Faint auroral streamers over Cape Bird; one in the 

 N. An auroral patch on the N. slopes of Mount 

 Eirebus. A bright luminous haze now extended 

 20° up around most of the horizon, chieflv from 

 S.W., S., E., and X. 

 2.00 Aurora, stretching from X. to S.E. Sky overcast in 

 the evening. 

 24th. Sky overcast. 



25th. Overcast in the early morning hours, clearing some- 



what in the evening. 



20.00 An auroral glow in the X.X.E. 



21.00 The glow still visible. 



22.00 A faint curtain near the horizon, extending from X'. 

 to X.X.E. 



23.00 A glow visible to the X. by E. 



24.00 Two long nebulous arcs, trending X.X.E., extended 

 across the sky ; one from a point 15° up in the 

 X.X.E. to the S.E., the other from the direction 

 of the top of Mount Erebus towards the S.E. 

 These curtains were bowed on Mount Erebus. 

 26th, 2.00 An auroral glow to the S.E. behind Mount Erebus, 

 and to the X.X.E., reaching a height of 15°. 

 3.30 Two nebulous curtains, trending to the S.E. : one 

 60° above the horizon, the other close to the S.E. 

 horizon. The lower one showed brightest, and 

 was of a dull-reddish colour (probably owing to 

 twilight affecting the eye). 

 4.00 A luminous glow and nebulous patches extending 

 from X". to S.E. In the E.S.E. this extended 

 to a height of 30°. 



17.45 Daylight still strong in the X.W., and only first 

 magnitude stars visible. A thin veil of haze 

 hung over the Ross Island highlands, so that 

 by 18.00 the mountain could only be seen by the 

 light of the aurora behind it. A very bright cur- 

 tain was observed ; this extended in a nearly 

 straight line, trending about N.W., and appearing 

 to be on the near side of Mount Erebus and 

 about 20° above the horizon. In azimuth it 

 extended from X T .X .E. to E.S.E. Faint streamers 

 lose 10° above the base of the curtain ; these 

 trembled as the excitation travelled across 

 them. The excitation travelled towards Mount 

 Erebus, aoparently from the X. at the X. 

 end and from the S. at the S. end. There 

 was also visible a passage both ways of excitation 

 from the brighter portions of the curtain. As the 

 luminosity waxed and waned it spread outwards
