Topics discussed in this issue include active galaxies and cosmology, interstellar and intergalactic medium, and astronomical instrumentation. Papers are presented on modeling rich clusters of galaxies, optical variability of NGC 7469 in 1967-1987, the structure of the broad line region in Fairall 9, the resolution of the compact core of quasars

This paper presents a first observational investigation of the faint Of?p star NGC 1624-2, yielding important new constraints on its spectral and physical characteristics, rotation, magnetic field strength, X-ray emission and magnetospheric properties. Modelling the spectrum and spectral energy distribution, we conclude that NGC 1624-2 is a main

Table 3 gives a catalog of HII region positions, diameters and absolute emission line logarithmic fluxes for NGC 4736. Table 4 gives a catalog of continua logarithmic fluxes adjacent to [OII], Hβ, [OIII], Hα, [SII] and [SIII] emission lines of NGC 4736 HII regions. (2 data files).

Observations of the Seyfert galaxy NGC 985 have revealed large-scale extended ionized zones, covering a large fraction of the ring-shaped structure of this galaxy. These ionized regions are a major contributor to the total far-infrared emission of this object. An interaction driven starburst is proposed to explain the main features of this galaxy.

The effects of atmospheric turbulence on astronomical observations from the Observatorio del Teide (Tenerife) and the Observatorio Roque de los Muchachos (La Palma) in the Canary Islands are characterized, summarizing the results of recent measurement campaigns. Data on image quality, atmospheric transmission, and IR conditions are presented in
