brightest when a patch of light from below appeared. Length of streamers 2°, altitude of 

 display 20°. Temperature, - 19° F. No clouds, light airs from N.E. true. 



At 4h. 35m. a.m., dull glow in S.W. by S. (magnetic), fading away towards N.W. (magnetic). 



6h. a.m. Patch with faint streamers between N.E. and N.N.E. magnetic. 



8h. a.m. Parts of three arcs, apparently concentric. The outermost, starting on the horizon 

 at E.N.E. (magnetic), rose gradually to 30° at N.N.E. (magnetic). Within this rose a smaller 

 portion at N.E. (magnetic), extending to N.N.E. (magnetic), where, like the last, it was discontinued. 

 At N.N.E. (magnetic) rose the third, which just cleared Observation Hill, and then, rising to 

 20° or 30° over the hills at W. 5° N. (magnetic), dropped to the horizon again S. or a trifle E. of 

 S. (magnetic). The arches were formed entirely of sheafs of vertical rays. The rays were very 

 brilliant at times in the N.N.E. and N.W. (magnetic) of the arc. The rays were throughout 10° 

 or 20° in length, except a few persistently longer and narrower and bright rays in S. (magnetic). 



Duration some 15 minutes at least. Movement was not flickering, but from N.E. to N. 

 (magnetic) and W. (magnetic) by gradual transportation of the whole arc, or i-ather fading at 

 N.E. (magnetic) and simultaneously appearing in N. and W. (magnetic). No wind, Ijut strong 

 wind sprung up soon afterwards. 



lOh. p.m. Faint aurora clouds near zenith. 



June 8. — -At 4h. a.m., faint auroral streamers from S. 5° W. to W.N.W. (magnetic). Altitude of display 

 from 15° to 45°. Length of streamers 2° to 20°. Patch of auroral luminosity in S.W. by W. 

 (magnetic). The display was evidently shining through a thin mist. 



June 10. — An extensive, though faint, aurora glow, extending from E. to S.E., observed at Oh. 5m. a.m. 

 Altitude 12°. No streamers. Temperature, - 22° F. Wind, 1-2. 



No sign of aurora at 2h. Om. a.m. 



At 4h. Om. a.m. very extensive faint aurora glow over hills N.E. to S.E., with one streamer 

 due N., bright in comparison, especially just above the hills, reaching an altitude of 20°. 



At 6h. a.m. the conditions were exactly the same, except that the single streamer was at 

 N. by E. (all bearings true). Temperature at 4 a.m., - 24° • 5 F. ; at 6h. Om. a.m., - 23° F. 

 Light wind, clear sky. 



At 7h. 45m. to 8 a.m., vertical beams arranged more or less closely together to form an 

 arc, which extended from near N.E. (magnetic) to S. magnetic, across N. and W. Altitude 

 at each extremity the visible horizon ; at its highest over N.W. magnetic, about 20°, or a little 

 more, to 30° at the summit of the streamers. Some of the W.N.W. streamers were 30° in length, 

 but were very faint. Some of the N.E. streamers were very bright and glowing, the glow lasting 

 for a few seconds. 



The S.W. and S. streamers were all faint, long, and very narrow, sometimes from 20° to 30° 

 in length from the horizon. All the S. streamers appeared to be inclined to the right of 

 the vertical, all the N.E. to the left. The end of the arc at the N.E. was indefinitely 

 reduplicated and the ends of each piece turned upward rather from the horizon. The dark 

 section of sky below the arc was well marked. - 21° -3 F. High E. airs (true). No clouds. 

 Apparent movement S. to E. true. No corona. 



June 11. — 6h. a.m. Faint arc of streamers, highest above Observation Hill, discontinued eastwards just 

 past that point. Greatest altitude 15°, E. extremity near Mount Discovery. Streamers appeared 

 to be issuing from a dark cloud-like space below them and extended for 3° or 4° towards zenith. 

 The streamers had a wavy, or flickering motion, but were always faint, the most pronounced 

 being to the W. of Observation Hill (bearings true). 



8h. a.m. Auroral arc S. to E. true, formed of faint streamers. Altitude 20°. Tempe- 

 rature, - 21° F. No wind, clear sky. 



llh. a.m. Faint aurora streamers, 20° in length, stretching across zenith from N. by W. 

 S. by E. magnetic. - 28° F. Wind E.S.E. No clcuds, clear sky.
