Mr. TatTiock gave an interesting description of the recent 
auroral displays, as follows :— 
Remarks on the Aurora of February 138, 1892. 
The aurora was observed from about 6.30 to 7.15 P. M. in West 
78th Street, near Riverside Drive, where an uninterrupted view was 
secured of the phenomenon. This aurora presented some curious 
and unique features, the principal of which are as follows :— 
The color of the luminous veil was a dull fiery red, such as is 
seen from a furnace when the flame has disappeared. Mr. Tatlock 
stated that in all auroras of great brilliancy which he had previously 
seen he had never before observed this peculiar tint. 
The streamers were more nearly radial than the speaker had ever 
before noticed, and the peculiarity of them was that there was no 
undulatory motion in a direction parallel to the horizon, such as is 
usually seen. They presented the appearance of the light from an 
electric search-light directed toward the heavens, and the only 
variation in the display was in the degree of intensity of the light. - 
The arch with the dark cloud beneath was particularly well defined 
throughout its entire length. The luminous appearance extended 
to a far greater degree on the western side of the pole than on the 
eastern. This appearance was, probably, occasioned by the fact 
that the moon had a high declination, and being near the horizon 
’ was then shedding its light strongly upon the eastern side of the 
aurora. Such portion of the veil on the eastern side as was visible 
appeared to be of a peculiar greenish-gray color, this appearance, 
undoubtedly, being caused by the position of the moon. 
Mr. Tatlock also referred to the auroras of the fall of 1881 and 
spring of 1884, which were noted at the times they appeared for 
their brilliancy and extent. In connection with the aurora of this 
year, however, there was no band of auroral light extending from 
east to west and passing through the zenith, such as was visible at 
both of the previous auroras referred to. 
At the conclusion of these remarks the meeting adjourned.
