25th, 16.30 A weak curtain crossed in a W.N.W. direction just 

 N. of the zenith. Several streamers descended 

 below the general level in an eastern extension. 

 It crossed the horizon of the S. slope of Mount 

 Erebus. 



17.00 The curtain had now drifted to the X., and crossed 

 the E. horizon just X. of Mount Erebus. Assum- 

 ing the curtain to be low, the travel appeared to be 

 at the rate of about 8 miles per hour. The 

 brightest luminosity had now shifted to the E. 

 end. Half an hour ago, as it crossed the S. flank 

 of Mount Erebus, it appeared very low, at times 

 appearing to haze the horizon. As it travelled 

 X. it stood clear of the summit of Mount Erebus, 

 the smoke-cloud standing black against it. It now 

 appeared, however, to stand higher generally. 



17.10 The central portion of the curtain had now faded, 

 though both ends were still visible. 



17.20 Portion of a faint curtain to the W.N.W. ; this was 

 the remnant of the earlier reported curtain, which 

 had now drifted further to the X. 



17.40 Xo aurora visible. The upper portion of the horizon- 

 haze to the W.S.W. was faintly luminous. 



18.00 A faint auroral band crossed the zenith in an E. and 

 W. direction, extending towards the TV. horizon. 

 This appeared to trend more truly E. and W. than 

 the one seen an hour ago (i.e., it had swung from 

 W. by X. to true W.). 



18.1o The same band now extended across the whole sky, 

 passing to the E. over the S. flank of Mount 

 Erebus. It was now verv faint, more so than the 

 Milky Way. 



18.30 Xo definite aurora. A strong luminous glow on the 

 S. slope of Mount Erebus. 



tq'oq ! Xo aurora visible. A slight luminous glow above the' 

 iqV horizon to the S. and E. 



20.00 The luminous glow along the X. slope of Mount 



Erebus was especially strong. 

 20.10 The glow on the X. highlands of Ross Island was 



stronger and abundant streamers ascending from 



it. The outline of the horizon was sharp against 



the glow. A few faint streamers appeared above 



the S. highlands of Ross Island. 

 20.30 Xo definite aurora, only a weak glow along the 



horizon of the highlands of Ross Island. 

 21.00 A weak luminous haze around the X.E., E., and S. 



horizon. 

 21.30 Xo aurora. Slightly hazier atmosphere, though much 



less so than ]ast evening. 

 21.45 Streamers rose over Ross Island highlands from 



X.E. to S.E. In the S.E. a curtain was weakly 



developed. 

 22.00 Well-defined streamers rose from the horizon along 



the X. highlands of Ross Island to Cape Bird. 



Also there was a small patch of curtain 40° up 



in the S.E. skv.
