Afterglow of GRB 990510

This is a false-colour composite of the area around the optical image of the afterglow of GRB 990510, based on three near-infrared exposures with the SOFI multi-mode instrument at the 3.6-m ESO New Technology Telescope (NTT) at La Silla, obtained on May 10, 1999, between 23:15 and 23:45 UT. The exposure times were 10 min each in the J- (1.2 µm; here rendered in blue), H- (1.6 µm; green) and K-bands (2.2 µm; red); the image quality is excellent (0.6 arcsec). The field measures about 5 x 5 arcmin 2 ; the original pixel size is 0.29 arcsec. North is up and East is left.
