 1902. 

 May 11. 2h. a.m. Very faint aurora, forming an incomplete arc. Total altitude, 15. No streamers. 



6h. a.m. An incomplete arc, height about 8, moderately bright and composed of short, 

 closely set streamers, in patches, very fluctuating. In 15 minutes no trace visible. 



May 13. 6h. a.m. After a very clear and still night in which no aurora appeared there were two very 

 faint beams rising some 10 from the western horizon (magnetic). 



May 14. 6h. a.m. Air very still, faint streamers from S. to N.W. magnetic, altitude up to 40, also small 

 circle of aurora light near zenith. No colours. 



May 31. Two patches of aurora glow just over hill in S.W. magnetic, very faint. Time 6h. a.m. 

 Temperature, + 13 8 F. Wind E.S.E., 2-3. 



June 1. At 8h. a.m., faint aurora beams in W.N.W. magnetic. Altitude of beams or streamers 

 between 10 and 20. Temperature, -2 -9 F. Clouds St. and Ci.-s. Wind N.E., movement 

 rapid, visible for very short time. 



June 2. At 6h. a.m., two faint streamers visible for short time in S.W. magnetic, altitude 15 to 40, 

 rising from behind hill. Temperature, - 3 F. No clouds. Wind E. by S., 2. 



June 5. 2h. 15m. a.m. Very faint, but rather extensive, aurora. A glow above the hills from 

 E. to S. (true) in a low arc on the horizon. Temperature, -16 '5. Wind E. by N., 4. 

 There were also a few faint beams in the S., altitude between 20 and 30. Also an indistinct 

 curtain, or ribbon of rays, very faint, and stretching across the heavens towards the S.E., and 

 within a few degrees of the zenith. 



4h. a.m. A faint arc, 20 in height, from N.N.E. to W (magnetic). - 15 F. 



Midnight. Faint aurora in N.N.E. to W.N.W. (magnetic). Altitude 20. 



June 6. At 8h. a.m. Aurora curtain from N.E. (magnetic) to S. 5 (magnetic) through W. (magnetic). 

 The curtain rose rapidly from 10 to 40 in altitude. There was very little perceptible movement 

 among the rays, but great and sudden variations in the intensity of the light. Phenomenon 

 lasted about 20 minutes and then entirely disappeared. Temperature of the air, - 17 F. No 

 clouds. Wind E. by N., 3. 



At 8h. p.m., faint aurora glow in N.W. (magnetic). - 9 F. Clear sky. Wind N.W. 

 The glow moved round very gradually to W.S.W. (magnetic), taking nearly two hours to reach 

 that point ; no streamers visible, altitude no more than 5. The temperature fell to - 28 F. in 

 early part of afternoon, but rose again very rapidly with wind. 



June 7. At Oh. 45m. a.m. observed fairly strong aurora in form of rough, broken-up arc, stretching 

 from N.E. (magnetic) to S. 20 W. (magnetic), and passing through zenith. Altitude 40 in 

 N.E., and down to summit of hills and behind them in S. 20 W. The phenomenon can scarcely 

 be said to have taken the form of an arc, the light was too broken up and was more of the 

 nature of luminous clouds, difficult at times to distinguish from the Milky Way, and varying 

 greatly in intensity. The average width of these "clouds" was from 1 to 3. No streamers 

 whatever were visible, and very little movement was perceptible. The only movement appeared 

 to be from S.W. to N.E. (magnetic). The glow at times became fairly intense, but never even 

 faintly red. Stars of 3rd magnitude were frequently entirely eclipsed. The interval in time 

 between maximum glow and fading away of any particular patch was a matter of a few seconds, 

 viz., from 20 sec. to 50 sec. No clouds. 



4h. 2m. and 4h. 7m. a.m. were the times of the brightest displays of a colourless aurora, 

 stretching from S.W.S. to N.E. (magnetic), with ;i brighter patch in the S.W.S. (magnetic) and a 

 fainter one in the N.E. (magnetic). The intervening part showed only a glow which occasionally 

 faded away. The only streamers seen were in the S.W. by S. (magnetic), and these were
