230 BARNARD— SELF-LUMINOUS NIGHT HAZE. 



between Cassiopeia and Perseus, and was io° under Polaris. It 

 was io° broad. Another ran through Alpha Cassiopeia and met 

 the first near the southwest horizon. There were several streams 

 of it from the intersection running upwards. These were as bright 

 as the Milky Way near Alpha Cygni. The sky between was very 

 clear. At ii'' lo™ the luminous band in the northeast was between 

 Alpha Persei and Capella. It was bright — brighter than any part 

 of the Milky Way. There were many less bright strips to the east 

 of the zenith. No aurora. (On August 14 there was a large au- 

 rora.) 12^^ 45™ "• All the sky except overhead was unequally covered 

 with luminovis haze. In the east and northeast there were great 

 long streaks of it, 10° or more wide. Also in the south. This was 

 as bright as the Milky Way. It was very strikingly dark where the 

 sky showed between. 



Aug. 16, lo*^ o™. A very feeble glow low in the north, like a 

 very faint aurora. No luminous haze to-night so far. At 10'' 20"" 

 there was a broad strip of luminous haze running from Altair east 

 by north through a point in a 22'^ 20"\ 80°. It was 10° broad and 

 quite noticeable when looked at for a few minutes. 11'' 40™: 

 Strong aurora with streamers and very low arch. 12'' 20™: Aurora 

 not very active, but strong glow. At 12'' 50™ there was only a 

 strong auroral glow. 



Aug. 18, 10'' 55™. No aurora, but sky luminous ; perhaps some 

 luminous haze in the south. 15'^ 52'": East edge of a broad sheet 

 of luminous haze passing over. Alpha Arietis. 15'^ 58™: The south 

 edge of this was passing the Pleiades. 16'' 2"^: East edge over Ju- 

 piter. 16'' 23"^: It was now massing up into little patchy clouds. 

 There was a great amount of it all over the sky. It was pale white. 

 There were some dark clouds lower in the east against the dawn. 



Aug. 19, 10'' 15"' to 10'' 45™. Looked carefully for luminous 

 haze, but none was visible. Sky very thickish ; INIilky Way very 

 dull. 15'' 15'": Sky very dull. No luminous haze or clouds. 15'^ 

 33"' : No luminous haze. Sky thickish ; specially thick over Jupiter 

 and the Pleiades. Some misty haze — not luminous. Some zodiacal 

 light at 15" 42™. Some feeble luminous haze above Jupiter and 

 the Pleiades. A great deal of dark haze ; a long mass of it was 

 probably feebly luminous in Cassiopeia and evidences of it at a
