2oth 3 2.00 Aurora same as observed at midnight. 



4. (JO Aurora still observed, but concentrating more to 



the S. 

 8.00 Faint in the N. and X.E. No display noted during 

 the middle of the day. 

 17.00 A remarkable nebulous arc extending from E. to W. 

 over the hut ; streamers absent. A second parallel 

 arc is faintly outlined. 

 18.00 Auroral streamers rising above the highlands of Ross 



Island and continuing steadily. 

 20.80 A remarkably fine display extending in a X. and S. 

 direction along the length of Ross Island. For 

 half an hour a definite symmetry was observed in 

 relation to Mount Erebus. Part of this time it 

 was of the nature of a complete circular invest- 

 ment, and appeared to have a diameter of some 

 20 miles. It was not truly circular, exhibiting 

 more the outline of Ross Island. 

 21.15 The aurora still good, but much diminished in 



brilliance. 

 22.15 Very faint aurora. 

 20th, 21.15 Faint streamers appearing over the highlands of Ross 



Island. Luminous-edged clouds to the S.E. 

 27th, 2.00 Auroral lights from zenith to the E. 



4.00 Ditto. 

 •30th, 2.00 The sky previously obscured began to clear, and a 

 faint aurora was noted along the highlands of Ross 

 Island both N. and S. of Mount Erebus. 

 4.00 An auroral arc to the X. 



8.30 The illumination, which had continued since pre- 

 viously noted, travelling more to the X., now 

 Avaned. 

 9.30 An illuminated border appeared very distinctly on 

 the condensation clouds over Ross Island. 

 17.30 A curtain of streamers rose from the highlands of 

 Ross Island extending from Mount Erebus south- 

 wards. The streamers were very strong, and ex- 

 tended to a great height. As usual, united below 

 to form a uniformly illuminated selvage. In this 

 particular case the lower border of the curtain 

 appeared to ascend to a higher altitude as it 

 passed over the cone of Mount Erebus. The 

 excitation travelled particularly rapidly to-night. 

 18.00 A condensation cloud drifting from the X. showed, 

 when S. of Mount Erebus, a bright luminous edge. 

 The illumination increased, and a few minutes 

 later auroral streamers extended upwards from 

 the cloud edge, and were noted as far S. as Hut 

 Point. Other clouds in the sky did not show 

 luminous edges. Later on other clouds showed an 

 auroral glow with streamers rising from their 

 upper surfaces. During this time no curtains 

 crossed the cloudless portions of the sky. 

 18.301 The sky obscured, but auroral glow perceptible 

 22.00) through breaks at intervals. In particular there 



appeared one long arc. 

 24.00 Faint aurora to S.E. bv E.
