NO. 9 BRIGHTNESS OF LUNAR ECLIPSES FISHER 9 



c = 2.5 The red light of the umbra was so intense, that during totality it pro- 

 duced distinct shadows of the telescopes and other objects illuminated 

 by it. 



Arcimis, Cadiz, Spain, {2,^) ; clear after beginning of totality; weak 

 astronomical twilight. 



04.3. d N. e. and telescope, aperture not stated ; no details were distinguishable 

 by either. 

 A. H. S., (31) ; place and sky not stated. 



6^{> inch reflector, after beginning of totality; what struck me most 



was the absence of bright spots, such as Aristarchus. 



1877 VIII 23; 1. 761; Grade 2 



c Antarctica, E. Indian O., Malay Pen., Nova Zemlya, Greenland, Labra- 



dor, Carribean Sea, E. S. Pacific. 

 Johnson, Crediton, Engl., (z?) ', "ot a cloud throughout. 



c 1.4 d 2^/4 inch ; Mare Crisium, Fecunditatis, Nectaris, Tranquilitatis, Sereni- 



tatis in a smoky gloom 



Rand Capron, Guildford, Engl., (39) ; sky not stated. 



d = 2.2 8^ inch ; as shadow began to pass off ... . the indistinctness notice- 

 able during approach and continuance of totality gave way to a con- 

 siderable sharpness of the moon's features as seen through the shadow. 

 The shadowed part glowed with a richer copper tint, on which were 



seen dark, almost black, spots and patches A good field glass 



rendered them hardly less distinct. 



3^ inch ; the dark spots or patches were distinguished to be moon 



details, but they were remarkably sharp and well-defined. [He says 



the same of details with 3^<t inch before totality.] 



Maunder, Greenwich, (38) ; sky not stated. 



c = 2.3 .... to the n. e. the eclipsed part was fairly bright and of a coppery 



hue, and the details of the surface seen with great distinctness 



Elgcr, Bedford, Engl., {2>^) ; exceptionally favorable circumstances. 



a 2.7 b .... details visible in the finder [of the 4 inch]. 



1878 VIII 12; 0.590; Grade 



c White Sea, Greenland, Labrador, Florida. 



Maunder, Greenwich, (41) ; sky not stated. 



c:=2.5 Finder of the great equatorial; .... the eclipsed part completely cut 

 out, the shadow being so dense and black that the outline of the moon's 

 limb could not be traced under it, even in imagination ; nor could any 

 features be made out on the eclipsed part, except at the very edge of 

 the shadow. 

 Slack, Forest Row, Engl., (42) ; occasional cirro-stratus. 



c = 2.s 6]/4 inch reflector; Copernicus faintly visible as a pale white spot 

 .... most of the umbra coppery, but not bright or transparent. All 

 through the eclipse the umbra was darkest at the approaching margin 



for a width about equal to that of Copernicus Moon's limb 



always visible, if faintly. 



E. E. M., (40) ; place and sky not stated ; probably somewhere in 



England.
