extending from behind Mount Terror to N. end of White Island. At times streamers rose to 5* 

 altitude, and were bright. Lateral movement rapid. 



lOh. 25m. p.m. Aurora curtain from N.E. by E. (magnetic), 30 above horizon, to N.W. 

 magnetic, 20 above horizon. Altitude of centre 30. No rays, but all a cloud-like mass of 

 irregular form with inside edge sharply defined. Brightest patch in magnetic meridian. 

 Width of curtain in some places 5. Rapid movement towards zenith, but slow lateral 

 movement. 



Display had faded before lOh. 35m. p.m., leaving only a faint glow in the N.W. 



lOh. 44m. p.m. Large faint arc from E. magnetic to N.W. magnetic. Streamers in E. and 

 dense patch of light in N.W. magnetic. Altitude of apex 45. 



lOh. 55m. p.m. Patches of light near zenith (N. magnetic). Strange milky appearance of 

 space of sky through which aurora has passed. 



Midnight. A comparatively bright, extensive, rapid-moving auroral display. The most 

 noticeable feature was that the lower edge of the arc was the better defined, though neither edges 

 were sharp ; the extremities were rather broader than the centre. A fine arc, about one-fifth 

 part of a circle, its breadth not more than 1; altitude at its centre 8, where it was also most 

 brilliant, but of extremely variable and rapidly changing intensity, limits E.S.E. to S.E. by E. 

 (true). From the E.S.E. point to 70 altitude there were a considerable number of detached 

 " lights " spreading in azimuth at 30 altitude, and appearing to be parts of an extensive, but 

 incomplete curtain. A few streamers were visible, starting brightly, but fading completely away 

 before reaching an altitude of 20 two of these at S. and S.S.W. points (true), and three between 

 E.N.E. and E. by S. points. The whole display extended from E.N.E. to S.S.W. (true). Tempe- 

 rature, - 36 2 F. Weather b. Calm. 



June 19. 2h. a.m. Auroral display of same extent as at midnight, with the exception that there was no 

 arc visible. Intensity very rapidly changing from fairly brilliant to most faint. Temperature, 

 - 41 F. b. Calm. 



4h. a.m. Three faint streamers N.N.W. to N. by E. true, fading away completely before 20 

 altitude. 



6h. a.m. Very faint aurora S.E. and S.S.E., 12 altitude. Temperature, - 28 F. Weather b. 

 Wind light, variable air. 



8h. a.m. Faint aurora S.E. to E.S.E. 



4h. p.m. Seen from Sound. Aurora extending from E. to S., at an altitude of 10 to 20, 

 formed of diffused streamers, some visible from ship, showing above Observation Hill. Minimum 

 temperature in Strait, -51 - 5 F. Temperature at time, -32 -5 F. b. Erebus smoke 

 going E. 



8h. p.m. Bright arc of streamers from N.E. to S.E. (true), altitude 9 to 15. 



lOh. p.m. Disconnected auroral curtain in S. and S.E., altitude 30 to 40. 



Midnight. Auroral glow on the N. side of Crater Hill. Faint glow in S. 



June 20. 2h. a.m. Auroral arc from Crater Hill to Observation Hill. 



4h. a.m. Aurora light in E. true. No definite arc or curtain. 



6h. a.m. Faint aurora streamer from Crater Hill to Observation Hill. 



6h. p.m. Auroral display in E. horizon. 



Note below is of aurora witnessed in Sound, behind Observation Hill : 



[Between noon and 6h. p.m. incessant display from E. to S. by E. (true). 



Ih. p.m. A bright wavy line, general direction horizontal, altitude 20, continuous and 

 without streamers. During the afternoon streamers rose from it, their lower end forming 

 brilliant luminous patches in the line, which began to take the form of an arc ; then streamers
