New observations of BS and BT Cnc were performed during the STEPHI VII campaign in 1996 February. An overall run of 115 hours of data was collected. Different methods have been used to analyse the time series, bringing the detection of 2 frequencies for BT Cnc and 3 frequencies for BS Cnc above the 99% confidence level. A comparison with the

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.
