NO. 9 BRIGHTNESS OF LUNAR ECLIPSES FISHER I 5 



c ^ 4.2 4>4 inch ; the ecHpsed part was very dark, grayish black. 



V. Kotikoly, O'Gyalla, (89) ; sky not stated, but a halo stopped obser- 

 vations later ; astronomical twilight. 



c =: 4.2 6 inch ; at mid-eclipse could see the eclipsed part only with the bright 

 segment out of the field. 

 Krueger, Kiel, (go) ; sky and means not stated. 



The brilliancy of Aristarchus in the surrounding gloom was very 



striking. 



1891 V 23; 1.306; Grade i 



c N. W. Pacific, Saghalien, N. Russia, Italy, Sahara, near C. Palmas, 



Graham Land, S. Pacific. 

 Wooster, Ballarat East, Victoria, (96) ; beautifully clear. 



c=::i.7 8 inch reflector; some of the larger and bolder formations were 

 traceable during the whole of totality. After passing the center of 

 the shadow, though still wholly immersed in it, the N. and E. parts 

 became much lighter, quite a pale ash color, in which Sinus Iridum, 

 Plato, Aristarchus, Grimaldi, etc., stood out boldly. 

 Jackson, Constantinople, (94); moon rose out of haze and fog; 

 apparently clear thereafter ; weak astronomical twilight about end of 

 totality. 



d = 3.7 6 inch; [Y2 hr. before end of totality] Aristarchus and the region 

 immediately north of it became conspicuous, and increased in bright- 

 ness from that time forwards. The moon was visible to the n. e. 

 throughout. 

 Leimtsky, Kharkov, (95) ; cloudless sky, astronomical twilight. 



c S.I d 3 inch ; the whole disk plainly visible, with some formations visible but 

 dim. 



1891 XI 15; 1.393; Grade 2 



c Antarctic ice, Indian O., B. of Bengal, near Yakutsk, Alaska, Rocky 



Mountains, near Manzanillo, S. Pacific. 

 Gore, Ballysodare, Ireland, (98) ; clear and cloudless sky. 



d i.3e Binocular; markings on dark part pretty conspicuous. 

 Power, Cape Observatory, (100) ; clear. 



b:=i.8 N. e., [from context;] the coppery hue characteristic of "bright" 

 eclipses was distinctly visible .... there were darker patches on the 

 coppery surface .... it resembled drawings of Mars, with patches 

 of darker shade scattered over the moon's surface. 



Fenef, Beauvais, France, (97), and Decroupet, Soumagne, both with 



good sky, used opera-glasses, and report seeing the spots and con- 

 figurations. Others with larger telescopes agree as to the brightness 



and visibility of details. But Leslie, Southampton, Engl., (99), clear 



sky, "glasses," says that "the darkness and absence of color of the 

 shaded part of the moon was even more marked in this eclipse than 

 in that of October 4, 1884." 



1892 V 11; 0.953; Grade 2 



c Antarctic ice, S. E. Pacific. 



Codde and others, Marseille, (lOi) ; good conditions.
