We present a detailed mode identification performed on the 1994 Whole Earth Telescope (WET) run on GD 358. The results are compared with that obtained for the same star from the 1990 WET data. The two temporal spectra show very few qualitative differ

The pulsating DA white dwarf R 548 was observed for 46 h in October 1993 in an eight-site campaign. New peaks near the known doublets in the Fourier transform are found.

The integrated magnitudes of 221 Galactic open clusters have been used to derive the luminosity function. The completeness of the data has also been discussed. In the luminosity distribution the maximum frequency of clusters occurs nearI (Mv) = −3

It is found that the differential extinction ΔE(B - V) in open clusters, which may be due to the presence of gas and dust, decreases systematically with the age of the cluster. Consequently we can infer that the average gas removal time must be abou

Integrated magnitudes and colours of population I synthetic clusters have been derived using the theoretical evolutionary tracks given by Stothers and Iben and an age-dependent initial mass function (IMF) obtained from the data of Tarrab. A compariso

PhotoelectricUBV magnitudes and colours have been determined for stars in the field of NGC 1931. The reddening across the cluster varies from 0 . 33 to 1 . 20. A distance of 2.16 kiloparsecs has been estimated for the cluster. It is concluded that th

The age distribution of galactic clusters is obtained from well-observed star clusters, and it is concluded that the observed age distribution of clusters within 1000 pc is not seriously affected by the selection effects. If we assume that the rate o

Two photoelectric records of the occultation event on 10 March, 1977, obtained by two 102-cm-aperture telescopes, spaced 1500 km apart, are critically analysed and indications of a complex structure of distribution of occulting material surrounding t

The results of photometric observations of the occultation of BD-19° 4222 by Uranus on April 26, 1981 from two stations in India conform with the model proposed by Elliotet al. (1981).
