An exceptionally
bright Gamma-ray
Burst (GRB
221009A) was caught by
the Fermi Gamma-ray Space
Telescope (left image in animation). While Fermi can see a
particularly large field of view it isn't able to precisely locate
detections accurately (typically within a few arcminutes to a few
degrees depending on the energy of the detection). So telescopes at
other wavelengths are employed to not only localise events and also
obtain further clues as to their origin. Recently, we used
CSIRO's ASKAP
radio telescope, which also has an excellent field of view but
with much greater resolution, to localise the source and monitor its
evolution over time. The image on the right shows the ASKAP field of
view in comparison to Fermi and the inset image shows the detail seen
within that field and the detection of the GRB in radio. The detection
was reported
in GCN 32736.
