6h. a.m. Beams of aurora appearing above the hills to an altitude of 8" to the E. (true). 

 Intensity faint. Light N. airs. b. - 19° F. Some still fainter beams at about 10° to 20° 

 altitude in the S. true. 



8h. a.m. Faint aurora in E. and N., l)right arc from N.W. to S.E. true. 



lOh. a.m. Faint, but extensive, aurora in E. and S. true, altitude from 10° to 60°. 



Noon. At about noon a low aurora arc on S.E. horizon. Apex about 3° in altitude, and 

 almost exactly in magnetic meridian. Rapid motion in light from left to right, or W. to E. 

 magnetic. (Seen from the Sound some distance from ship.) 



(Plate H.) Auroral arcs and streamers were visible all afternoon, waxing and waning in 

 S.E. and at times bright. Altitude 5° to 50°. 



8h. p.m. Faint aurora, visible in patches, E., S., and S.E. ; brighter jjatch and streamer 

 inW. 



1 Oh. p.m. Faint bands in N.W. magnetic. Light W. airs. b. -23°F. 



Midnight. Faint bands in same position. 



June 4 — 2h. a.m. Very faint aurora light, just above hills, bearing E. true. Altitude 10°. 



4h. a.m. Faint aurora light in S.E. true. 



6h. a.m. Faint streamers of aurora light from N.N.W. (true) to S. (true) at altitude 15° to 

 20°, varying in intensity, but never bright. Intensity of light equal to star of 4th magnitude. 



8h. a.m. Streamers from N. to S.W., brightest to the E. 



lOh. a.m. Faint irregular streamers in S., altitude 50° to 80°. Arc from S.E. to S.W., 

 altitude 30°. 



June 5. — 4h. a.m. The uppei' edge of an auroral curtain showing above the upper edge of a bank of stratus 

 cloud. Altitude 20° and stretching from N. to S.E. true. The curtain was by no means sharply 

 defined on its upper edge, but appeared to be of remarkably even breadth (2° to 3°), and, though 

 very moderately brilliant, of equal intensity at equal altitudes throughout. Two streamers 

 running up to the zenith from N. and N.W. true. Wind S.E., 4-9. Temperature, - 23° F. 

 Weather bq +. 



6h. a.m. Very faint aurora in N.N.W. 



June 6. — 6h. a.m. Aurora in N., E., and S., very faint, strongest in E., altitude 40°. Calm. Tempera- 

 ture, - 29° F. b. 



June 14. — 2h. a.m. One bright auroral streamer passing through zenith, direction N. bj' E. to S.W. true. 



June 16. — 6h. a.m. Two streamers seen for few minutes in gap (Observation Hill). 



8h. p.m. Faint auroral arc of streamers from S.E. to S.W. through S., altitude about 40°. 



June 17. — 2h. a.m. Extensive auroral arc from N. to S. horizon across zenith ; plainly visil^le in brilliant 

 moonlight. Lasted about 3 minutes. 



Midnight. Faint aurora light E.S.E., altitude 6° to 10°. 



June 18. — 2h. a.m. Faint arc from E., altitude 5°, to S. by W., 6°. Apex E.S.E., altitude 11°. 



4h. a.m. Faint patches of aurora between N.E. and E. by S., and altitude 8° to 20°. 



lOh. a.m. Bright streamers in S.E. to N.E. and N. true. Part of corona in zenith. Two 

 arcs of streamers N. to S.E., altitude 40° and 60°. Very bright streamer in N. 



At about Ih. 30m. p.m. saw faint and low aurora arc in magnetic N., and almost at right 

 angles to magnetic meridian. A large faint arc was observed soon after lOh. a.m. rising from 

 Observation Hill and sweeping across the sky in a N.N.W. direction true, crossing to within 5° 

 of zenith to the E. 



During most of afternoon there was a bright and extensive aurora low down on horizon,
