Auroral light N.W. - 



Faint auroral light in S.E. to alt. 30° 



Arch (1) S.E. toN.W., brightest ou horizon to S.E., alt. 



to 12°. 

 Light becoming more diffused, faint streamers in N.W. - 

 Very indistinct arch from above-mentioned bright patch 



to S.E., through Cassiopeia and y and S Ursaj Majoris. 

 Arch becoming brighter, lower edge, which passes through 



Capella, sharply defined. 

 A confused mass of curtain-shaped aurora below the arch 



on the horizon to E.S.E. (1). 

 Above-mentioned aurora becoming brighter and moving 



to E. 

 The Pleiades now in the centre of this patch of aurora; 



more aurora in N.W. ; three parallel curtains, colour 



yellowish. 

 Spectroscope shows a single yellow-green line - 

 Narrow streak of aurora from near jS Pegasi through 



zenith to within 10° of Arcturus. 

 Curve of aurora from N.N.W. on horizon through ^ and 



V) Ursje Majoris to the E. of Cassiopeia. 

 Bright patch of aurora between C^assiopeia and Saturn, 



a wave of bright light moving therefrom towards Ursa 



Major. 

 A small patch of rapidly-moving aurora with faint vertical 



streamers near the horizon, below and to northward 



of Capella. 

 Aurora iu N.W. now passes between ? Ursje Majoris and 



Arcturus, and above Ursa Major to Cassiopeia. 

 Aurora moved from Cassiopeia to zenith - - _ 



„ moving to the southward and passing through 



a LjTX. 



Another arch halfway between Ursa Major and the 

 horizon ('5). 



Small patch of aurora (2) near Arcturus ; the rest of the 

 arch has a striated structure. 



There are now two principal arches, one fi'om horizon to 

 Arcturus, and Aquila to Pegasus, and 10° above S.E. 

 horizon, the other from the latter point through Cas- 

 siopeia and 5 Ursa3 Majoris to the N.W. horizon, an 

 irregular curve from Cassiopeia through Taurus towards 

 S.E. horizon ; these are all moving slowly towards the 

 S.E. 



Streamers on horizon to the E. just below Saturn 



Aurora on the E. horizon, increasing, striated, and with 

 rapid motion ; other arches less bright southernmost 

 now 8° S.W. of Altair. 



Cloud of aurora 20° to 30° in width in the zenith and to 

 S.E. and N.W. 



The whole sky more or less covered with faint aurora 

 except to the S.AV. from the horizon to about 12° alt. 



Aurora rather brighter and now extending fi-om the zenith 

 to E. and S. to 30° from horizon, faiufer in N. and W.
