191 1-] BARNARD— SELF-LUMINOUS NIGHT HAZE. 251 



September 30. At 9h 15m for 10° above the east by north 

 horizon a broad luminous band 50° long was seen just aboye and 

 involving Aldebaran. It stetched to the south of the east point 

 and in brightness resembled the appearance produced by the moon 

 just before it rises. The light was soft, yet conspicuous. At 

 loh lom under Capella was a large soft diffused light — dift'using 

 to the east and beyond. This light was steady with no fluctuations. 

 Nothing of a similar nature was visible in the north or elsewhere. 

 The sky was dull and more or less luminous. At loh 55m the 

 illumination extended half way up to Aldebaran and the sky near 

 the horizon was luminous like moonrise. This extended from 25° 

 south of east to nearly due north, rising much higher under Capella 

 — a very soft and steady illumination. I2h om. The illumination was 

 feeble and diffused. At I2h 30m it was very feeble and mostly in 

 the northeast — scarcely noticeable. At this time dark smeary haze 

 was visible all over the south. Xo evidence of an ordinary aurora 

 was seen during the night. The sky was luminous all over, but 

 not so much so as on the twenty-ninth. 



October i. There was a bright aurora. 



October 2. 8h om. A pale illumination was seen in the low 

 north and also in the low east. The effect was probably auroral. 



October 6. The night was more or less luminous and misty. 



October 28. There was a luminous sky at night. 



October 30. I3h om. The night was very luminous with fully 

 as much light as would be caused by a one quarter full moon. The 

 Milky Way was scarcely visible. Watch easily read by the glow 

 at I4h om. At i5h and i5h 30m a luminous haze covered all the 

 low northern sky as high as half way to the pole. This was not 

 strong and did not look like an aurora. It seemed simply to be 

 luminous haze. 



November i, i2h 15m. The sky was remarkably luminous every- 

 where. In the north from the horizon to halfway to the pole the 

 sky appeared more luminous than elsewhere. No trace of an arch. 

 The illumination did not look like that from an aurora, but at 

 I5h 30m a strong auroral arch had formed. 



November 10. i2h om. There was a great amount of luminous
