In order to test the calibration technique to be used on the GOLF solar oscillation resonant scattering spectrometer on the SOHO mission, observations with a modified instrument have been carried out at Izana, Tenerife since 1989. Different methods of analysing data are compared. These show that calibration by means of a magnetic modulation

NGC 5506 is a peculiar Seyfert (Sy) galaxy: it has a Sy2-like optical spectrum, but broad permitted infrared lines and a high X-ray luminosity as compared with Sy2's. By means of optical long slit spectroscopical observations, we obtained the velocity field, density and reddening of the narrow line region (NLR), as well as a detailed analysis of

The results of a long term programme of broad band JHK photometry, for a sample of 360 late type stars, made at the Observatorio del Teide (Tenerife, Spain) are presented. Transformations between these magnitudes and those of several currently used systems (CIT (Elias et al. 1982 and Carney 1983), Johnson (Johnson 1966, and Lee 1970), and ESO
