Description: 
KAO was established in 1955. Its equipment makes it the largest 
astrophysical observatory in the U.S.S.R. There are five departments in the 
Observatory: (1) Stellar Physics, (2) Physics of Nebulae and Interstellar 
Space, (3) Solar Physics, (4) Radio Astronomy and the Ionosphere, and (5) 
Design of Astrophysical Instruments. 
The Soviet Union's largest reflecting telescope, with a 2,600-mm- 
diameter mirror, is located here. A vacuum spectroscope which makes pos- 
sible the study of the weakest magnetic fields and the speed of gases in 
the solar atmosphere with approximately 10 times greater accuracy than for- 
merly was installed at the Observatory in 1961. Some very fine solar 
equipment, including a Babcock-type solar magnetograph, also is installed 
here. 
Within the complex of the Crimean Astrophysical Observatory is a 
second astrophysical observatory near Simeiz. Although the Observatory near 
Simeiz is older than the one near Partizanskaye, it is now a branch of the 
latter. 
It publishes an Izvestiya.
