1903. 



April 2i. — 2h. a.m. Auroral streamers, of very slight intensity, to the E.N.E. and S.E. true. Altitude up 

 to 30'. Temperature, -19°- 4 F. Wind E. by N., 3-4. No clouds. 



April 25. — Midnight. Auroral streamers, visil)le for a few seconds at intervals of 30 seconds, S. to about 

 E.S.E. Sky cloudless. Longest streamer S., altitude 45° to 50° ; shortest from horizon to 10°. 

 Temperature, - 25° • 2 F. Calm. 



April 26. — 2h. a.m. Streamers N. to S.E. true, but very weak, although bright at times, especially one to 

 the N., which was broader than usual, but low. Calm. Temperature, - 28° • 2 F. No clouds. 

 Extreme altitude 55° to 60°. 



4h. a.m. Vertical rays, bearing from S.S.E. true to N.W., of varying intensity. One over- 

 head stretching across the sky S. to N. Calm. Temperature, - 39° F. No clouds. 



April 27. — 4h. a.m. Faint vertical rays showing from N. round to E.S.E. 



6h. p.m. Faint streamers from zenith to S. and S.E. true. 



8h. p.m. Very faint auroral arc of streamers, extending from S.E. to S.W. true. Altitude 

 of apex 7°. Temperature, - 37° F. Calm. b. ' 



Midnight. Faint aurora streamers from E.N.E. to S.W. Altitude from 20° to 35°. No 

 clouds. Temperature, -27°F. No wind. 



April 29. — 4h. a.m. Streamers E.N.E. and S. by E. Arc E. to S.S.E., faintly visible at 3h. 45m. a.m., 

 increased greatly in brilliancy in two succeeding minutes. Altitude 20°. At maximum brilliancy 

 a lower arc, altitude 15° to 17°, appeared. Both arcs rapidly vanished and were indistinguish- 

 able at 4h. a.m. As arcs grew, streamers paled, and, at disappearance of former, latter again 

 shot up, reaching an altitude of 40° in direction noted above. The greatest brilliancy was in 

 centre of arc and = star of 2nd magnitude. Calm, bright. Temperature, - 10° F. 



6h. a.m. Streamers flashing at intervals of 2 to 3 minutes in N.N.E., and an occasional faint 

 gleam in S. by E. direction. Brilliancy eclipsed by growing twilight. Calm. b. Temperature, 

 - 14° F. 



April 30. — 2h. a.m. Faint streamers, N.E. and E. true, reaching to 60°. 



4h. a.m. Faint streamers in same position. Temperature, - 8° F. N.E., 2-3. b. 

 9h. 35m. p.m. Two faint streamers in W. true, near zenith. 



May 1. — 2h. a.m. Fleeting streamers to S. and S.E. true. 



4h. a.m. Fleeting streamers over Observation Hill and the land eastward. 



May 4. — 2h. a.m. Very faint auroral arc over Observation Hill. Apex N.N.W. (magnetic). Altitude 

 12°. One extremity W. 5° N. magnetic, other invisible. Clear sky, no wind. Temperature. 

 -3°-5F. 



May 6. — 6h. a.m. Faint diffused auroral cloud in the zenith, which soon disappeared, b. Clear starlight, 

 Temperature, -3° -5 F. Calm, light S.E. airs. 



May 7.— 8h. a.m. Auroral light. Temperature, - 7° -5 F. Calm, light snowflakes falling. Clear sky in 

 zenith. Apparent movement of aurora to S. 



May 16. — 6h. a.m. Faint auroral streamers in N.E. and S. true, altitude 60°, and cluster of streamers in 

 zenith. Temperature, - 50° F. Calm and bright. 



May 20. — 8h. a.m. Very faint auroral streamers from S.E. to W., altitude 25° to 45°. 



May 21. — 8h. a.m. Faint aurora in the S.E.
