Sky field around GRB 000131
Colour composite image of the sky field around the position of the gamma-ray burst GRB 000131 that was detected on January 31, 2000. It is based on images obtained with the ESO Very Large Telescope at Paranal. The object is indicated with an arrow, near a rather bright star (magnitude 9, i.e., over 1 million times brighter than the faintest objects visible on this photo). This and other bright objects in the field are responsible for various unavoidable imaging effects, caused by optical reflections (ring-shaped "ghost images", e.g. to the left of the brightest star) and detector saturation effects (horizontal and vertical straight lines and coloured "coronae" at the bright objects, and areas of "bleeding", e.g. below the bright star).
Technical information: The photo is based on three 8-min exposures obtained with VLT ANTU and the multi-mode FORS1 instrument. The optical filters were B (seeing 0.9 arcsec; here rendered as blue), V (0.8 arcsec; green) and R (0.7 arcsec; red). The field measures 6.8 x 6.8 arcmin 2. North is up and East is left.
