Using the precise VLA position, researchers used the Gemini North telescope in Hawaii to make a visible -
light image that identified a
faint dwarf galaxy at the location
of the
bursts.
Quick follow - up observations undertaken with the 8.2 - m Antu instrument at European Southern Observatory's Very Large Telescope in the Paranal and the 1.5 - meter Danish telescope at La Silla identified a
faint, point - like object in visible
light that was fading rapidly, the optical counterpart
of the gamma - ray
burst called the «afterglow» (Pedersen et al, 2000).
