V. ly TITLE: Integrated Visual Photometry of the \Solar Corona in 1952 and 1954 PERIODICAL: V sb.: Polnyye solnechn. zatmeniya 25 fevr. 19525 1 30 iyur-ya 1954, Moscow, AN SSSR, 1958, PP. 62-80 TEXT: The results of visual photometry of the solar corona at the total eclipses of 1952 and 1954 are reported. Detailed theoretical considerations are given which pertain to determination of the corona integrated brightness, Poss".'-~-- errors in determination of the corona integrated brightness are discussed, as well as their necessary reduction. Wedge photometers were used in observations. Illumination from the corona was determined as a difference between illuminations evaluated by the first photometer (corona + sky) and the second photometer (sky), The author proposes to observe the Moon, the Sun, or laboratory standards for the photometric standaidization of the photometers. The problem of allowance for atmospheric extinction is discussed in detail. It is pointed out that the Card 1/2 S/035/60/000/04/08/017/ AOO I/AOO 1 Integrated Visual Photometry of the Solar Corona in 1952 and 1954 atmospheric state changes during the eclipse total phase and this can give rise to considerable errors in the final results, Four methods of determining the atmos- pheric transparency during the whole eclipse are proposed. The results of observations of the eclipses in 1952 and 1954 are presented. The following conclusions are drawn from the comparison of data on five eclipses observed by the expeditions of the Astronomical Observatory of LGU (1936-1954): The method develqped by the author yields the results which are in a better mutual agreement than those obtained earlier; the accuracy of observational results of one eclipse amounts to 10-20%; fluctuations of the corona integrated brightness from one eclipse to another were not detected in the material obtained, hence they were small; the mean corona brightness, referred to the mean values of parallaxes, is equal to 0.07 lux or 0.23 of the brightness of the full Moon, or 5.10 _7 If the Sun's brightness.

Four eclipses were observed. A Rosenbeig-type astrophotometer was used as a visual astrocolorimeter. A detailed description of the equipment and observational method is given. A team of 6-7 persons performed the observat-i=s, During the total phase, up to 19 estimates were made by eaoh, The accuracy of a single measurement amounted to 7 OT03. A standardization attachment was used for weakening the Sun's brightness when comparing its color with the color of tire corona; this attachment included a neutral scattering screen and gratLng reduoE~-.s, Card 1/2 S/035/60/000M/11/017 Visual Colorimetry of the Solar Corona AOO1/AOOl A method is described of eliminating the selective attenuation effect in the Earth's atmosphere from the results of colorimetric comparizon. It 15 pointed out thaz the effect of the bluish background of the sky scattered light can be neglected, since its brightness is lower, by three orders of magni-,.;ude, than. the brightness of the observed regions of the Inner corona. The photograph of the equipment is given, as well as the composite table of colorimetric determi- nations of the solar corona color. The table contains also the results of photographic determinations of the color excesses for comparison, The resul-T;s tl~ show that the radiation of the corona during all the eclipses was sligbtly reddi-r than the solar radiation.

Uch. zap. LGU, 1958, Nr 273, pp 120 - 143 ABSTRACT: A comparison was carried out of the surface of Mars and terrissrial land- scapes, simultaneously in two optic parameters, i.e., albedc and -~olcr. Thi, results of the visual observations carried out at -the Tashkent Astron'C'mfo Observatory in 1956 were used.

The same apparatus, in conjunction wit " a medium-sized elbow telescope, was used to measure over 100 samples of terrestrial cc-Trers under laborator-j conditions.

The statistical comparison with the data for Mars was :,,arried cut ---y tha m~st-_~I'd of diagrams - brightness versus color. It was found that not one of the tvces of terrestrial covers was similar to those of Mars, since the value of the yel-13-vness Lidex of the latter was higher by 0.6 units of the color index than that for -thm- St_di.~_d typz_z of desert covers. Therefore, the wide-spread opinion held on the semblance cf -,he ,f the surfaces of Martian mainlands and the terrestrial- deserts was fvund -,c z~~ wrong. Bibl. 17 titles.

The data obtained correspond to scattering by particles, which have the nature of dielectric balls with a radius of about 0.4 or by a mixture of balls of different dimensions with the most frequent radius of about 0.1 . The author considers, basing on the optic characteristics obtained, two hypotheses to be probable: according to the first hypothesis, t1he particles re- present ice crystals or condensation nuclei covered by a water layer; according to the second hypothesis, they must be mineral particles of silicate composition. Hoffmeister attributes in his lecture "The Nature and Origin of Nuctilucent Clouds" the phenomenon of noctilucent clouds to the penetration of micrometeor streams into the terrestrial atmosphere. At high altitudes, the latter cause the ad- ditional glow of the night sky, which can be observed in the form of bright bands. The meteorite material clusters at the boundary between the stratosphere and iono-zphere and becomes visible in the form of luminous clouds.

Sharonov wave.a lecture on "The Frequency of Phenomena of Nostilucent Clouds From Observations at the Stations of the USSIV, in which he noticed that the statistical investigation-of the distribution of noct-Ilucent clouds over The latit,udes and the seasons, which was carried out on the basis of materials published in the li-terature, Is Insufficient, because the number and the activity of the observers are not equal. Regular observations were performed during the IGY at 220 stations, which gave material suitable for statistiCs.

It is necessary, for the correct determination of the frequency of ce- currence of noctilucent clouds, to consider the meteorologic conditions. The observations of noctilucent clouds are usually impossible or nearly impossible, when tropospheric clondiness exists.

The results of integrated photo- metry and colorimetry of Mars carried out by means of a Rosenberg photometer are presented. The following average values of albedo are determined: geo- metric 0.139, illustrative 0.208, spherical albedo 0.154; yellowness index is +1.066. The visible albedo of continents in the center of the disk has the C ard 1/3 S/269/63/000/002/026/0,47 The surface and atmosphere of Mars from... A001/A101 value 0.184 determined by absolute photometry of iddividual regions using the method of reflecting screen. For seas the albedo value fluctuates between 0.06 and 0.12 amounting on the average to 0.105. Darkening toward the disk limb was decreasing with development of fogs and was increasing when the at- mosphere was clearing. The yellowness index for various regions of continents was obtained on the average +1.09 and for seas +0.89. It is concluded thereof that seas are also colored red but not so intense as the color of continents; their greenish tint perceived visually is not real and has a physiological origin. The results of photometric and colorimetric investigations of ter- restrial specimens are presented, from which it follows that desert covers are not similar in color to Mars. The problem of yellow fogs is discussed, as well as their interaction with violet clouds; a hypothesis is expressed that the latter are located in the lower layer of the atmosphere. The orange color of the planet surface and of some fogs Is ascribed to the presence of large quan- tities of powder-like limonite. The author presents a general scheme of eolian processes on Mars, according to which seas are zones of eolian erosion and de- flation; atmospheric currents carry away dust from them revealing partially a darker and less tinted original ground.

The first of these methods consists in reduction of an object to disappearance, i.e., decreasing of visible contrast by means of proper optical accessories to the magnitude of the threshold of con- trast sensitivity of sight. Technically it is accomplished most convenient~y.by the superposition on the object and on the background of a veiling brightness Card 1/3 S/269/63/000/002/027/037 An experience of determining contrasts on the..; A00IIA101 which is created by the light of either the planet itself or a special light source. Various observational schemes by this method are described, as well as their practical application to Martian seas in'1956. The second method consists in creating in the sight field of the telescope of some artificial object on whtch can be seen an arbitrarily changed contrast of brightness. An observation, consists in equalizing this contrast with the visible contrasts of objects on the disk of the planet. The author describes the application of a Rosenberg photometer, during which the image of an artificial planet of the same size, brightness and color was obtained side-by-side with the image of Mars. Details were seen on the artificial disk whose contrast it was posdble to change by means of a special contrast-measuring wedge. The third method, consisting in estimat- ing the brightness of details by one of the proposed by-sight scales, is dis- cussed and rejected due to its insufficient accuracy. Instead a method is pro- posed which is based on mounting an artificial object with constant brightness contrast in the telescope sight field; this object is compared with details of the planetary disk. The theory of this and its technical description are pre- sented. The results of Mars observations by various visibilimetric methods are intercompared and compared with data of photometric measurements.

Photometric and colorimetric observations show that for all the regions of the lunar surface the scattering diagrams are strongly elongated towards the Sun, the color differences are very sm-all and the albedo ratios do not exceed 1:3. As there is little doublt in that morphologically the different regions of the lun r surface are composed of rocks of different petrographic composition, the above noted uniformity can be explained by the lunar surface being covered by a layer of special material, which is the result of the alteration of the initial lunar material by exogenous factors (eg., meteorite impacts). Examples of such material can be volcanic alag and. lapilli, the surface of which is very uneven having deep depressions with steep sides and sharp edges. ~2 I 80~y, 'I.;XJ ~, 1J) J'N'T I ON SOV/4831 slhrlr_rr~v, vsev~,Itirl Vasilyt,-vir~h, Dc_~-Lor ,,f Physi-s and Ma--hematlcs Ghf.,.-) my znay,~7m o Duie, (What We Kn-w About the 114oon) [Leningrad] Lenizdat, !960~ ?6 p. 10,000 ropies printed.

After a general intro- duction the author summarizes the endogenous and exo- genous theorie.~ of crater-origin, stating that the former is endorsed by geologist A. V. Khabokov and Academician A.N. Zavaritskiy and the ater by Pro- fessor V.V, Fedynskiy, Professor K.P. Stanyukovich and P.F. Sabaneyev. Describing attempts made to ascerT-ai-n-TFe -existence of a lunar atmosphere, the author mentions the work of Academician V.G. Fesen- kov who, finding no traces of polarization in the Card 1/'/ penumbr~L of the twilight zone, concluded that theL--/ 0 67822 SOV/26-60-1-2/45 The Moon anlal Its Nature mass of the lunar atmosphere must be at least 1 mil- lion times less than E;~~th`s.(Plore recently the esti- mate has dropped to 10-'- ). The existence of rarefied gas aroundthe moon was confirmed by the second So- viet space rocket. The gas is of an unusual iono- spheric type and was traced by a trap located in the container which s.!~parated itself from the rocket and recorded the currents of ionized gas particles. These were first registered 10,000 km from the moon after which their number increased. Discussing the luminescence frequently obseiovecl on the unlit areas of the lunar surface, the author states that computations made with the instrument container neither confirmed this phenomenon nor revealed the presence of any noticeable magnetic field. More pre- cise data on luminescence were obtained by the Czech scientist F. Link who made photometric lunar obSe Card 2/7 bations during an eclipse, correlated them with caT- 67822 -DOV/26-60-1-2/4'5 The Moon and Its Nature culation data and, in most cases, distinguished ef- fusions of brightness which he attributes to the lu- minescence of the moon's surface. Owing to the com- plexity of the formulae for brightness calculation these results have yet to be verified. Using the me- thod of the Fraunhofer lines in research on lumines- cence, Professor N.A. Kozyrev obtained only one posi- tive result from spectrogrTms of the central hill in the Aristarchus crater. Durin- the night between 2 and 3 Hovember 1957 lie noted a bright emission spectrum on a spectrogram of the Alphonsus crater and ascribed it to a gas-cloud from one of the "hills" illumined by some kind of radiation. At the obser- vatory in Leningrad University a detailed chart was made snoTuin~~ the brit3htness and coloring of lunar Cal features by means of tints characteristic of meteor- Card 3/7 ites and terrestial rocks like magma. Nlo analogous 67822 SOV/26-60-1-2/45 The Moon aid Its Nature rocks were observed on the optical parameters pri- marily because of the moon's low reflectivity. Spectrographic methods showed a monotonous rise in the albedo curve from the violet to red areas of the spectrum. It is assumed that the lunar surface is in fact dark brown in color, being only a little lighter on the "continents" and a little darker in the "seas". This would suggest that the moon is co- vered by some monochromatic blanket deposit of fair- ly recent origin. New lunar researches confirm this theory. Describing attempts made to ascertain tem- peratures on the moon, the author states that the blanket deposit is impervious to radiation on a wave-length of 10 microns, but becomes increasingly viable to radio waves as wave length is extended. Consequently it is possible to determine surface temperature by thermoelectrical methods and sub- Card 4/7 surface temperature by radio methods. On account 67822 SOV/26-60-1-2/45 The Moon and Its Nature of the low heat-conductivity of the porous surface deposit it is assumed that if the moon is devoid of atmosphere, heat is transferred by small-area points of contact between dust particles and by radiation of heat in the intervening spaces. Conducting a photometric study of the lunar surface, Academician N.P.Barabashov of the AN USSR (AS UkrSSR, and Pro- fessor A.V kov showed that the nature of the re- flection--o-1-TE-esun's rays from the moon demonstrates the existence of elevations and denressions invisible through a telescope. Such irregular terrain seems to disprove the theory that the moon's surface is covered with fine dust. N.S. Orlova, a Leningrad astronomer, explains that reflections from the light and dark areas of the moon are formed in such a man- ner that much of the li-ht-stream is deflected tow- ards the sun. This type of reflection could only be Card 5/7 produced by a highly irregular surface such as could 67822 SOV/26-60-1-2/45 The Moon and Its Bature never be formed by sand, volcanic ash or dust. The actual composition of the moon's surface is suggested in the theory of Professor N.N. Sytinghaya who con- siders that a substance similar tovyolcanic slag was formed by the impact explosions of~m_eteorite-swarms. This theory would also explain the uniformity of the lunar surface, especially if other processes (eg. lava formation, volcanic ash deposits, etc.) are at work at the same time. If this is sol meteorite swarms would soon impart a characteristic overall appearance to surface formations. Furthermore, the dark lunar coloring corresponds to that observed on meteorites which have passed through the Earth's atmosphere and can also be seen at high temperatures on basic and ultrabasic rocks containing large quan- tities of olivine and other high-iron silicates. According to the researches of I.A. Yudin this dark coloring is caused by the decomposition of the sili- Card 6/7 cate molecules and the formation of dark ferric 67822 -,07/2-0- -6- 0-1 -2/45 The Moon and Its Nature kSSOCIATION: oxides like iot*ite and magnetite. It is possible that some such process prevails on the moon. In concluding the author suggests that the 3arth may some day be subject to formations similar to those on the moon and expresses a hope that direct chemi- cal and petrographic studies of the lunar surface will soon be possible.
