... Impact on source motion in Galactic coordinate system is given by Kovalevsky (2003), Malkin (2011) l cos b = -A sin l, b = -A cos l sin b, where A = R0 02 /c is the galactocentric acceleration called hereafter the GA constant. ... We just have to return to the traditional many-centuries-old astrometric practice of modelling the position of a celestial object as a linear trend with two parameters: the position at the initial (conventional) epoch and the apparent (proper) motion. ... 2011). ...

... All the galaxies are divided into 4 groups depending on the environment type; every subsample contains more than 10 galaxies. ... An effect of environments is seen both for the nuclei and for the bulges: if we consider the clusters (Virgo and Ursa Ma jor) and group centers as dense environments and the field and group periphery as sparse environments, then in the dense environments the stellar populations of S0s are in average older by 4­5 Gyr than in the sparse ones. ...

Nova 1998 2 in M31 this image of the second Nova in M31 in 1998, was made from 38 exposures of 45 seconds integration time. It was made at September 21, 22h 20m UT. Telescope was a CG11 at f/6.3, no filters were used. The long list of processing steps caused the artefacts at the overexposed center of the galaxy and in many of the brighter stars. During the exposures thin clouds covered the sky but the CCD cuts through them, allowing me to obtain this result. ...
