Caption:
The fading transient afterglow of GRB 010222 as observed with the Hubble Space Telescope. Over roughly 19 days the
transient dimmed in brightness by a factor of 6. Using these images and others taken from the ground, the Caltech GRB
Collaboration found that this gamma-ray burst was collimated as a jet. Soon, several more images will be taken by HST
to monitor the continued fading and search for the host galaxy.

Caption: Color Hubble Space Telescope image of the field of GRB 010222. The large region around GRB 010222 shown, about
1/25th the size of the full moon on a side, is a fairly typical portion of the night's sky, littered with faint galaxies and a few
stars. The GRB originated from a distance of about 30 times further away from Earth than the spiral galaxy to the East
(left of the transient). The inset shows a close up of the region around GRB 010222. Several red galaxies are scattered
around the transient position; at least two of these are closer to Earth than the GRB and gave rise to detectable
absorption in the spectrum of the transient.
