H.. A. Hazen—The Sun Glows. 203 
_A very remarkable fact is to be noted in connection with the 
display of Nov. 26 and 27, and that is, the sudden brightening 
over an immense region extending over half of Europe, 
Over nearly the whole of the United States and British Co- 
lumbia, though it had not been specially noted for about a 
month previous. 
t may be interesting to note a few of the more detailed 
observations that have been made. 
_ fst. Just before and during the glow at night and after 
it in the morning, grayish, horizontally stratified, light clouds or 
Stri~ have appeared above the sun and have extended to right 
and left. These are invariably present with the glow, though 
the sky may be otherwise cloudless. On a careful examina- 
ton, in the evening, these strie will be usually found passing 
from a point 20 or 30 degrees to the left of the sun to the right 
and left and frequently overhead, reminding one forcibly of 
polar bands which are generally seen in eastern United States 
(where all these observations have been made) passing from 
S : to N.E.* In the morning in like manner strize are seen | 
passing above the sun and descending to the NE. or N. and 
SW. or S. Often the directions of these strise are confused 
and marked by cloud layers somewhat nearer the earth, 
What are these strie? On Feb. 1 at 5 P. M. with the sun 
10 high the strize were the plainest yet seen, many of them 
passing overhead in continuous lines to the NE. 
On the right of the sun they were mgre distinct than on the 
left, and the radiated structure was very plain, emanating from 
the N.E. point of the horizon. The next morning thesky was 
: Clear, it was even possible to separate ¢ Lyre into its compo- 
ite the striz were not visible at the first blush of morning, 
puta careful examination finally revealed them though very 
int and of limited extent. On February 2d the appearances 
ae about the same as the previous evening. In the S. a 
Plain Cirrus cloud was seen at a great hight, its well-marked 
ki dipped to S.B. and W.S.W., appearing as if at the out- 
ha of a great cloud system gradually advancing from S., 
Those the actual motion of the cloud was from west to east. 
i Streaks of cirrus while prominent did not have a sharp out- 
s2é and were more or less broken up, while the strie to the - 
ght were sharply defined and unbroken. At 5.30, the sun 
es Set, the cirrus streaks overlapped the striz and appeared 
‘P'ainly between them and the eye. At 5.35 the glow had be- 
; “> in the horizon but was at a very low altitude, the strie 
. Unchanged, while a slight blush just tinged the cirrus.
