September. 



1st, 1.00 An arc trending approximately E. and W., 30° up 

 in the S. A luminous cloud with streamers rising 

 from it low on the S.E. horizon below the arc. 

 2.30 Aurora fairly bright in the zenith and N.E. 

 3.30 A faint steamer-curtain in the N.N.E. 

 Overcast at 6 a.m. and snow falling. 

 2nd, 00.30 A nebulous glow behind a cloud to the N.W. 



2.00 A nebulous aurora in the N. from the horizon to the 

 zenith. Odd patches of auroral nebula in the 

 N.E. and above a dark cloud in the S.E. 

 4.00 A nebulous aurora in patches to the E.S.E. During 

 the evening the sky was clear for the most part. 

 20.00 An irregular auroral patch on the S. side of Mount 

 Erebus, just below .the summit, in the position 

 where a condensation cloud was seen earlier in 

 the evening. 

 22. (X) Aurora, absent. A mist formed and the sky became 

 overcast. 

 3rd, 2.00 An auroral knot in the W. Drifting snow during 

 the day. . In the early evening observation showed 

 the absence of aurora. 

 23.00 A faint curtain over the zenith, trending from the 

 S. to the zenith, then to the N.N.E. Third-order 

 stars onlv visible on account of the moonlight 

 (half-full). 

 4th, 1.00 A streamer-curtain seen faintly in the moonlight, 

 trending N. alid S. over the zenith. 

 1.30 Two parallel curtains close together and very steadv. 

 2.00 An arc from N. to S. 



In the evening the moon bright, so that only the 

 largest stars visible and aurora further obscured 

 by clouds. 

 5th, 2.4o Strong radiating cirro-stratus clouds developed about 

 this time from the E.S.E. to the N.W. Simul- 

 taneously two auroral curtains became developed, 

 trending about N.N.W. The westerly one ex- 

 tended from the N.N.W. to the zenith; the 

 easterly one extended from the N. by AY. to a 

 point some 30° E. of the zenith. The latter was 

 the brighter of the two curtains. They appeared 

 brightest between the cloud-belts, between which 

 they were scarcely visible. The excitation travelled 

 from the N. ends. Both curtains drifted slowly 

 N.W., the direction of the wind forming the 

 cloud-radiant. 

 Long daylight, moonlight, and thick weather all co- 

 operated for some time to mask auroral phenomena. 

 12th. Faint aurora noted after midnight. 



13th, 0.10 A very bright small curtain - aurora to the N. of 

 Mount Erebus at the same height as the top of 

 Mount' Erebus, concave towards Cape Bird. Also 

 a. long straight band, about 15° above the horizon, 

 extended from Cape Barne to the S. side of 

 Mount Erebus; this had long streamers, extending 

 for a height of 5°. At the time the moon was 

 bright.
