1902. 



April 1. At Ih. ii.m. observed faint curtain of aurora in N. true; altitude about 2" to 4; weak intensity 

 and slow movement. 



At Ih. 15m. a.m. aurora glow in N. true. Beams of aurora visible at intervals in N. until 

 about 3h. 30m. a.m. 



At about 3h. 2m. a.m. faint beam in N.N.E., occasionally stretching up towards zenith. 

 Temperature of the air, - 8 F. No wind, clear sky, bright moonlight. Little Ci.-s. cloud. 



April 2. Time Oh. 10m. a.m. Beam of aurora seen in S.S.W., about 30 above the horizon, very faint 

 and slow in movement. Bright moonlight. 



2h. a.m. Faint beam in N., about 5 above horizon, slow movement. Temperature, - 12 F. 

 Ci.-s. cloud, 3. Bright moonlight. 



April 3. Time 4h. a.m. Beam of aurora in S.W., very faint, slow movement. Altitude from 20 to 70. 

 Temperature of air, - 10 F. 



April 6. Aurora (very faint) observed at about 2h. 20m. a.m. 



At from 2h. 12m. a.m. to 2h. 22m. a.m. faint aurora arc stretching from S. to N.E. true, 

 apex nearly E. true, altitude 15"; occasional beams moving vertically, comparatively slow 

 movement. Intensity very low, but little stronger than the " Milky Way " ; certainly too weak 

 for spectroscopic observations. Temperature of air, - 10" F. Clear sky, no clouds. Very faint 

 mist over sky, giving stars a " watery " appearance. 



Aurora had entirely disappeared at 3h. a.m. 



April 7. At 9h. 10m. p.m., faint aurora glow in E., altitude 20, only visible for few minutes, it being 

 soon obscured by clouds. Temperature, -11F. Blowing a giile from S.E. 



April 9. At about 2h. 25m. a.m., M.T. (3h. 20m. p.m., G.M.T., on 8th), observed aurora in N. and N. by E. 

 true, in the form of three streamers radiating from N. (Plate 8). Very little movement 

 discernible in curtains, the vertical beams remaining stationary for a considerable length of time, 

 viz., 2 minutes, and only varying in intensity. The intensity was equal to a star of between the 

 2nd and 3rd magnitude. Temperature, - 3 F. Wind S.E., 4. No clouds. 



At about 2h. 44m. a.m. the two smaller streamers had almost faded away, but the principal 

 streamer had become more intense and stretched across zenith forming a very grand glowing 

 arc, containing faint tints of red, but with scarcely any appreciable movement in it. No 

 vertical beams at all. 



Phenomenon had entirely disappeared at 2h. 55m. a.m. 



April 10. From midnight April 9 to Oh. 20m. a.m. aurora arc visible, extending from S. true to E.N.E. 

 Apex of arc nearly due S.E., magnetic meridian, altitude 10. Intensity star of between 3rd 

 and 2nd magnitude. Slow movement ; constituted of vertical beams which remained stationary 

 for some time. Temperature of air, - 1 F. Clear sky. Only dark band of cloud in S. 

 beneath arc. No wind.
