Results of cooperative observations of the flare star EV Lac in September 1993 are presented. One of the about 30 optical flares detected was powerful enough to permit a quantitative analysis of its intrinsic radiation with the colour-colour technique. Sinusoidal brightness variations due to spottedness of the stellar surface was found to have an

To study some physical properties of comets of the Jupiter Family, we have compiled a new catalog of nuclear magnitudes. As a source for the catalog we have used Kamel's (1992) compilation of data from many different sources, adding measurements of nuclear magnitudes for the period: mid 1990 - mid 1996, taken from the IAU Circulars, MPCs, ICQs and

A large and deep ethnoastronomical fieldwork has been performed in the Canary Islands of Tenerife, Fuerteventura, Lanzarote, Gomera and Gran Canaria during 1995 and 1996. Numerous and challenging astronomical traditions, almost at the border of extinction, have been found among aged shepherds and peasants of these island.
