GRB 050904 at two epochs
Observation of the Gamma-Ray Burst GRB 050904 at two different epochs, i.e. about one day after its discovery with the Swift satellite (left), and four days after (right), in the near-infrared J-band. The burst becomes quickly fainter as can be seen by comparing the two images.
