established. The negative polarization of a comet's radiation, phase

dependence of integral brightness of comets, and nuclei surface of part of

the short periodic comet with refractory rind were investigated. The

molecular hydrogen was predicted; the negative magnetohydrodynamic

theory of comets was worked out, and the mechanisms of members of

unsteady phenomena in a comet were given and their connections with solar

activity were established. Investigations of Haley's comet were carried out

on the international IHW program.

•

  The complex investigations on the physics and dynamics of meteors were

carried out; the method of instantaneous expositions of the photographing of

meteors was worked out and utilized. The connection between concrete

meteoroid showers and comets and asteroids were established, and the

theory of the evolution of meteoroid streams and quasi-continuous

fragmentation of meteoroids was worked out. The connection between the

ionospheric heterogeneities and meteoric phenomena was established. The

flow of meteor matters to earth was determined and, jointly with other

institutions of the C.I.S. countries, a Standard was established. The

connection of the eleven-year cycle of the dynamic processes in the upper

atmosphere of the earth with solar activity was established, and new meteor

streams and associations were found. The physical properties of the E and F

ionospheric layers of the earth were investigated. New seismoionospheric

effects that allow us to predict large earthquakes of a magnitude of more

than 5 were established.

•

  The Institute took part in the compiling of a stellar catalogue, as well as

catalogues of geostationary satellites.

•

  Three new and several hundred variable stars, as well as the polarization of

radiation in protoplanet gas-powdered envelopes of the variable stars were

found. The mechanisms of the variability of the stars were given. The

Institute archive consists of more than 70,000 photoplates.

•

  The astrometeorology of Tajikistan was investigated.

For achievements in astronomy, the Institute was decorated by Order of the Red

Banner of Labor (1969). Two asteroids were named in honor of scientists of the

Institute.
