It is a matter of common knowledge that in processes of genesis and evolution of many solar phenomena participate magnetic fields of sunspots. ... As a basis for formation of the database we take data on magnetic fields, collected by set of observatories during many years of observations. ... Section "Magnetic field data" contains data of magnetic field observation for separate sunspots, presented in standard text format (ASCII). ...

. N OTE: . Only clusters with R<60 kpc were used to compute the spatial parameters and metallicity gradients for all subsystems except the corona. The numbers in parantheses give the number of clusters for which the corresponding parameter is known. The X O scale length of the old halo is strongly distorted by the observed asymmetry of the distribution of the corresponding clusters projected onto the XY plane ( Fig. 4А ) . discussion in the text | previous table .

... Its apparent diameter of 18.0 arc minutes corresponds to a linear extension of about 180 light years; Kenneth Glyn Jones mentions an estimate of even 20 arc minutes from deep photographic plates, corresponding to about 200 light years linear diameter. It appears somewhat smaller in amateur instruments, perhaps about 10 minutes of arc. ... Red: 20x3 minute subs, totaling 1 hour . Green: 20x3 minute subs, totaling 1 hour . ...

... OXIDIZED AND HYDRATED SILICATES ON M- AND S- ASTEROIDS: SPECTRAL INDICATIONS. ... In particular, it was shown that a considerable fraction (ab. 35%) of the mainbelt M-type asteroids have absorption bands at 3 µm [3, 6] diagnostic of water of hydration. At the same time it was found that the visible-range reflectance spectra of some M- and Sasteroids include absorption features characterizing presence of oxidized silicates [4, 5]. ...

... Galaxies with polar rings (PRGs) are a unique class of extragalactic objects, consisting of a ring or disk of gas, stars and dust orbiting in a plane nearly perpendicular to the disk of a central galaxy. ... At present, there are only about two dozen kinematically confirmed galaxies in this PRG class, mostly from the Whitmore et al. (1990) catalogue, based on photographic images. ... Examples of object from our catalogue SPRC (=SDSS-based Polar Ring Catalogue). ...
