Microsymposium 38, MS083, 2003 (A4 format) MERCURY: LOCAL VARIATIONS OF THE PHOTOMETRIC RELIEF. ... Because of trajectory and pointing angle constraints the planet could be observed from Mariner 10 only over a small range of phase angles between about 75o and 110o. Therefore the photometric investigations are restricted to measuring the distribution of brightness on the Mercurian disk. ... Raw versions of real-time processing pictures FDS 0000984 and FDS 0000986 were used (images 196 and 202). ...

... R-band images obtained at 0.8 arcsec seeing conditions have allowed us to separate foreground star from point-like extragalactic source and estimate their brightness separately. ... To study the nature and properties of the source, we observed it under high spatial resolution. ... CONCLUSION RTT150 optical observations with sub-arcsecond seeing and low resolution spectra confirm the hypothesis of superposition of a radio source onto a `normal' F/G galactic star proposed by [1]. ...

... Hazy skies usually mean steady skies, and steady air is just what the doctor ordered for observing planets and double stars. Mars is well past opposition and becoming less an item of interest as it shrinks in size, but Jupiter and Saturn are well placed in the early morning August sky. ... Their magnitudes are 4.2 and 6.0. ... It has an easily observed 10.6 magnitude central star. ... Cygnus is also host to a lot of small open star clusters that stand up to inspection under hazy skies. ...

THE ARGUMENT AGAINST LONG EXTRAGALACTIC DISTANCE SCALE Gaseous discs of S0 -- Sd galaxies appears to be gravitationally stable or close to stability. Dependence of the gravitational stability parameter of gaseous disc $M_g/M_c$ upon the color index $(B-V)^0_T$ which reflects a relative number of young stars, is found. Here $M_g$ is total mass of gas in a galaxy, $M_c$ - mass of gas which corresponds to marginal stability of gaseous disc at distances from center. ...

. This color image was obtained with Fuji color film (Super Plus 400) in focal plane of the 70-cm reflector (F = 27 m) at Lisniki Observatory by A.M.Evtushevsky. Data and time of observation: April 27, 1997, 21:25 LT. Comet-Earth distance: 1.7 a.u. Time of exposure: 10 min. Field of view : 3 minutes of arc. Distance between shells, in average: 15 000 km. Diameter of bright coma in the picture center: of about 5 000 km. Last updated: January, 2005.

... As then we removed from the Earth, we dived into a sky deeper and deeper. ... We saw immense red-hot spheres, liked suns, in illuminator of our spaceship. ... We saw our Earth, Mars, Mercury, and planets-giants, such as Jupiter, Saturn, Uranus and other. ... Also we saw a comet. ... The planet Upsilon was on our way. ... If we could speak the language of these two peoples, we could explain them what the war did on our home planet "the Earth", how many people were killed because of war conflicts. ...
