 1903. 



August 11. — At 7h. 30m. p.m. diffuseil aurora cloud in N. liy E. true, altitude 10', also a streamer 



stretching from altitude 15' E. true, passing within 1" S.W. of zenith and continuing for 



some distance toward.s W.S.W. Ci.-s. cloud over sky, so aurora must lie fairly strong to show 



through. Colour pale straw, with suspicion of pink. Blowing hard, but little drift. 



August 12.— 7h. Mm. p.m. Dilfused band fruni S.S.W. to W. true, aililudo 10 . Width of band 5'. 



8h. p.m. Two arcs extending from W. to E. in N. and S. (true), altitude of arc in N. 

 about 20', altitude in S. about 50'. Moderately bright. The arc in S. quickly faded out, but 

 one in N. faded and brightened intermittently. Patch of streamers to W . in form of a curtain, 

 but very ragged and faint. Glow to N.E. 



Midnight. Two faint vertical curtains of auroral light, bearing N. Ijy \\. and N. by E. true, 

 to an altitude of 20'. Wind E.N.E., 2-1. l)q. Temperature - 12' F. 



August 13. — 2h. a.m. Faint auroral arc l)etween E. by S. and S.I'], true, altitude 8' to 10', apex E.S.E. 

 true, 12\ Wind N.E. by N., 2-4. bq. Temperature, - 10' -5 F. 



4h. a.m. Two faint streamers X. and N.E. true, altitude 10" to 20". Wind N. by E., 2-3. 

 bq. -6-2F. 



lOh. p.m. Fairly brilliant display, consisting of a complete arc, extending from N. to 8. and 

 two streamers. The highest jjoint of the arc was due E. true, with an altitude of 15°. At its 

 E.S.E. point it was distoited by a relatively more lirilliant and wider zone of light with a 

 streamer rising out of it to 30° altitude. An independent ray also rose to 30' altitude to 

 the S.E., but did not quite reach to the arc. The breadth of the arc was between 2' and 3°, 

 the lower edge more defined than the upper, but neither particularly definite. Very rapid 

 movement and very rapidly changing in form. By lOh. 10m. p.m. the arc had completely 

 disappeared and was replaced by streamers of irregular altitude and interrupted in their lengths. 

 The streamers rose at various points where the arc had been, the extremes being at E.N.Ii and 

 S. by E. points, with two more in between. The altitude of the highest was 40". This latter 

 display was also very rapidly changing. Wind S.E., 2-3. - 13''2 F. Weather b. 



lOh. 20m. p.m. Diffused streamer from due N. true, spreading out fan-like to about 

 30° altitude, but one thin band from one side of the fan extending across the sky to the W. 



No aurora visible at lOh. 45m. p.m. 



At llh. 10m. p.m. fine arc in S., extending from N.W. magnetic to N.E. magnetic, 

 altitude of apex 25', and e.xactly in magnetic meridian. The N.E. extremity much the brightest 

 and formed of vertical rays, while N.W. and centre was rather faint and about 4° in width. The 

 whole display moved rapidly towards zenith and at the N.E. formed draped aurora of a greenish 

 tint, which appeared to brighten up with heavy gusts of wind. Blowing hard from S.E., and air 

 full of minute air crystals. A few isolated rays in N. true, altitude 40'. Shortly after a bright 

 draped curtain appeared a little to E. true of zenith, altitude 80°, and arc became very faint. 



At llh. 20m. p.m. only a few faint cloud-like patches here and there were visible. 



Midnight. Very faint aurora, incomplete arc E. to W. Greatest altitude S. true, 8', 

 varying in intensity rapidly, b. -12" -OF. Wind E. by S., 3-4. 



August 14. — 2h. a.m. Very faint, but extensive, aurora. Patches scattered about asymmetrically from 

 N. to S.S.W. 



4h. a.m. Extremely faint aurora N., N.N.E., and E., barely visible at times, b. Tempera- 

 ture, - 15° • 9 F. Wind S.E., 0-2. 



6h. a.m. Two very faint auroral streamers to the E., rising to 15°, rapidly changing, b. 

 -13°F. N.E. by E., 2-3. 



August 15. — Faint aurora seen from Sound at about oh. p.m., S.E. by E. true, the centre of display. Rays 

 to an altitude of about 20'.
