... Compact Extragalactic Jets. Radiointerferometry has played a crucial part in the studies of compact extragalactic jets during the last several decades. Submilliarcsecond resolution of Very Long Baseline Interferometry (VLBI) has enabled detailed studies of morphological, kinematic and spectral properties of radioemission from the jets. We will present a review of results from several latest VLBI studies of extragalactic jets. ...

... In this paper we present the results of detailed B, V, R, I, and H study of the isolated nearby blue compact dwarf (BCD) galaxy NGC6789. Judging from the literature the observed galaxy has not been resolved into stars up to now. ... The distance of the galaxy, estimated from the tip of the red giant branch (TRGB) is 2.1 Mpc which places NGC6789 close to the Local Group. ... Key words: nearby galaxies: dwarf galaxies (NGC 6789): distance moduli: star content . ... Distance. ...

... In addition, IZMIRAN comprises the St.Petersburg branch and magnetic ionospheric observatory in Kaliningrad. The history of IZMIRAN is largely that of investigating magnetic storms and sub-storms on the Earth surface, in circum-terrestrial and interplanetary space, initially by means of a network of ground stations of the Soviet Union (1930s - 1940s) and the nonmagnetic skunner "Zarja", then through the extensive use of magnetic measurements on artificial Earth satellites and automatic stations. ...

... We publish 16 Doppler imaging temperature maps for the years 1994-2002 of the active RS CVn star II Peg. ... Through Doppler imaging we want to study the spot evolution of the star and in particular compare this with previous results showing a cyclic spot behaviour and persistent active longitudes. ... The derived temperature maps are quite similar to the ones obtained earlier with a different methods, the main differences occurring in the spot latitudes and relative strength of the spot structures....

... Objectives of the study .

... A statistical study of OM eld acquisition (FAQ) o sets performed in nearly 1500 observations in Revs. 207 - 860, shows a systematic average deviation of -2.29 and -2.32 arc sec in X and Y axis respectively. ... The standard deviations of these o sets are 4.0 and 2.8 arc sec. Using this new boresight in the cross-correlations reduces these errors to average o sets of - 0.22 and -0.40 with standard deviations of 1.8 and 2.1 arc sec in right ascension and declination respectively. ...
