(596) Scheila is a large primitive asteroid observed with a comet-like apearence last December. We present near-infrared spectra (0.8-2.4 μm) obtained at...

V1647 Ori is a young eruptive variable star, illuminating a reflection nebula (McNeil's Nebula). It underwent an outburst in 2003 before fading back to its pre...

We present preliminary results of the surface photometry of a sample of blue compact dwarf galaxies (BCDGs). A total of 28 galaxies have been observed in the...

We describe the first results of a program to extend the Landolt calibration standards to at least V=19 mag and to calibrate fields separated from the celestial...

We present preliminary results of a simultaneous X-ray/optical campaign of the prototypical LMXB Sco X-1 at 1 10 Hz time resolution. Lightcurves of the high...

The OJ-94 international collaboration has been observing the light curve of OJ287 intensely at radio, millimetric, infrared and visible wavelengths. We present...

Comet C/2000 WM1 (LINEAR) was observed at ESO when it had its closest approach to the Earth at the beginning of December 2001 (geocentric distance: 0.32 AU)...

An unexpected dust cloud was identified around asteroid 596 Scheila on early December 2010 [1]. Our team has been monitoring its photometric behavior in order...
