... The Galactic low-mass X-ray binary GS 2023+338 was discovered during the burst on May 22, 1989 with the Japanise satellite Ginga (aka Galaxy). The flux reached 17 crabs (this unit of flux measurement is an bright X-ray source, Crab Nebula) at 10-35 keV. ... No other radio telescope worldwide carried out multi-frequency measurements. ... Upon 14 days the radio flux fell below the detection level at the RATAN-600 in relation to the decrease of the X-ray flux. ...

KN, KS, KM GEOMAGNETIC INDICES (from SGD Explanation of Data Reports) A full description of the indices Kn, Ks, Km is given in a monograph, "Indices Kn, Ks et Km, 1964-1967", edited in 1968 by the Centre National de la Recherche Scientifique, 15 quai Anatole, France, 75007 Paris, which contains these indices for 1964-67 while IAGA Bulletin No. 39 contains those for 1959-63. ... The indices are standardized according to the distances of the stations to the auroral zones. ...

... This is possible at modest cost due to the low moments of inertia of the telescope and enclosure. ... This same performance will be achieved in higher winds when the telescope enclosure is facing away from the wind, or by using wind screens. ... The telescope system (MILT) will be remotely operable with an on-site operator's assistance by an astronomer located at one of the ARC member institutions. ... Mean Wind Speed . ...

The principle of the existing reliability level of space engineering, and first of all, of rocket-launchers is laid into the milestone of the cosmonauts training (the successful launch of "Soyuz" space vehicle is close to 1, but it is less than 1), that causes a possible landing of space crews outside the regular landing site. ... However, search operations can be hampered by difficult meteorological and geographical conditions in the region of emergency landing. ...
