Karaenskiy interview with Soviet scientists Stepanov and Smolkov] [Text] Scientists of thl Siberian il -ult-d-of- -@Irff_ Mapngtis-m. the ionosphere, and radiowave propagation have started a dioramie test of a solar radiotelescope project. Its complex of structures will occupy approximately 50 hectares in the Bodar area near Baykal. Our correspondent asked institute director, USSR Academy of Sciences corresponding member L-VIadiplir Yevgenyevioh-Stepanov and radioastronomy laboratory chief Gennadiy Yakovlevich Smalkov to-conimien-C"6n-this new project. Question, What has necessitated the construction of such an instrument, Vladimir Yevgenevich? Answer: The 24th party congress directives provide for scientific research irl the new 5-year plan with the aim of developing long-distance conmiunications, television. and weather forecasting. Scientists are also continuing fundamental research in the sphere of astrophysics, interplanetary space, solar physics, and solar-terrestrial communications. Before us is the unsolved enigma of the sun--sunsports, chromonspheric flares, and phenomena accompanying them. During solar flares a colossal amount of energy is released in the form of wave and corpuscular radiation. The former reach the earth in 8.3 minutes, and the latter in a matter of several dayz, interrupting radio conuaunications, upsetting the magnetic field, changing the weather, and even affecting the health of people suffering from cardio-vascular complaints. The radiation level of the earth's environment during such periods increases to such an extent that space flights become dangerous. In order to learn how to forecast these processes and, consequently, predict the geophysical consequences of solar flares, it is essential to have a complete concept of their mechanism and dynamics. Question: But are there not many solar observatories in the world already? Answer: Yes, there arc, and our in@itltute has several optical telescopes of various kinds. They permit us to observe the solar surface--the photosphere and'the lower strata of the solar atmosphere, the chromosphere, With the aid of an artifical solar eclapse in a coronographic telescope it is also possible tc observe the upper strata of the solar atmosphere--the cornoa--but not in a direct line with the earth but at an angle of @O derrees. r4 Anpr Fg@ Release 2001/q3/2,6.,: 9)A-RDP9i-0Q787R00950,9,13@0 90 V 7V rol Cl A ved For Release -RDP96-00787ROQWOOI 30066.3 'c.rq1/03j26,L, cr beEl' in ot:a I Plar MagnctoL I)ur.tn,g no years 1963-1.966 speci,-Ais@:s at the sayall Observatory of the SibIZMIR (Siberian 'Lnstitute of 'I'ercestri.al magnoti@-,m, lonosphc!rc and Radio Wave Propa-attlon@ iinve wor,c@@t oii clio !ostg-a an(' tesLin@,, of Instruments for measurin(, the 2"ceman and Doppler eftocts in the zJhsorptlon and emission lines of solar plasma.
