31st, 4.00 Auroral phenomena in the N.N.W. to E. by S.E. 

 8.00 Aurora in the E. 



8.45 Long nebulous auroral arcs, uniformly illuminated, 

 extended along the highlands of lloss Island. The 

 luminescence shaded off towards the border of the 

 bands. This is the first appearance of this definite 

 type of aurora. In other parts of the sky a dull 

 auroral glow appeared. 



20.00 A most striking auroral curtain ran along the high- 

 lands in a more or less N.N. AY. direction. It 

 appeared to be very low over Mount Erebus and 

 to touch the present active crater. At one stage 

 it ringed the crater of Mount Erebus. For the 

 space of about four minutes it appeared strongly 

 coloured ; the colour hands were horizontally 

 stratified, red below, passing upwards through 

 yellow, greenish-white, and purple to blackness 

 above. The excitation producing the colour 

 travelled S. from the direction of Cape Bird 

 towards Mount Erebus. The arc as a whole 

 appeared to travel to the N. 



20.20 The arc still faintly red below. 



21.00 Absence of auroral phenomena.

June. 



A brilliant display in the form of curtains, streamers,, 

 and nebulous masses covered the sky E. of the 

 zenith from N. to S.W. 



Aurora distributed generally over the portions, 

 of the skv to the E. of the zenith from N. to- 

 S.AY. 



Long streamers in the N.N. AY. A luminous haze 

 continued faint during the day, and appeared 

 stronger in the evening. 



An aurora near the S.E. horizon. 



Aurora in the E. 



Faint aurora on horizon N. of Mount Erebus. 



A faint auroral arc extended nearly E. and W. over 

 the zenith. 



A single strongly-defined curtain extended someAvhat 

 N. of AY. over the zenith. This followed a straight 

 line over the ice of McMurdo Sound, but in the 

 vicinity of Ross Island curved to the N., so as to- 

 bring its course directly over the summit of Mount 

 Erebus. 



A nearly E. and AY. auroral band crossed the heavens 

 exactly as noted at this time yesterday. It con- 

 tinued eastward as far as the eye could reach. A 

 less strongly marked band extended from the N. 

 horizon towards the zenith. 



A bright glow, resembling an auroral haze, extended 

 round the horizon.
