We select 4 pointings for the Wide Field Camera (WFC) mounted at the prime focus of the 2.5m Isaac Newton Telescope (INT), located at the Roque de Los Muchachos Observatory, La Palma. We carried out observations from October 12 to October 14, 1999. (1 data file).

The observations were obtained with the automated 60cm telescope of Konkoly Observatory, Svabhegy, Budapest equiped with a Wright 750x1100 CCD using BV(RI)c filters, between 25 September and 14 December in 2003. (5 data files).

We perform a search for gravitational wave bursts using data from the second science run of the LIGO detectors, using a method based on a wavelet time-frequency decomposition. This search is sensitive to bursts of duration much less than a second and with frequency content in the 100-1100 Hz range. It features significant improvements in the

We present high time-resolution multicolour observations of the quiescent soft X-ray transient XTE J1118+480 obtained with ULTRACAM. Superimposed on the double-humped continuum g'- and i'-band light curves are rapid flare events which typically last a few minutes. The power density spectrum of the light curves can be described by a broken power-law

We subjected 106 new high-resolution spectra of the double-lined spectroscopic close binary varepsilon Lup, obtained in a time-span of 17 days from two different observatories, to a detailed study of orbital and intrinsic variations. We derived accurate values of the orbital parameters. We refined the sidereal orbital period to 4.55970d days and
