The Australian Square Kilometre Array Pathfinder (ASKAP) observed
the field of GRB 221009A/Swift J1913.1+1946 (Dichiara et al., GCN
32632; Kennea & Williams., GCN 32635; Veres et al., GCN 32636) at
888 MHz on 2022 October 12 from 07:00 to 13:00 UTC (2.70 to 2.95d
after the Swift/BAT trigger).
We detect an unresolved radio source at a position consistent with
the Swift/UVOT position (Dichiara et al., GCN 32632) with a
preliminary flux density measurement of 2.2 +/- 0.1 mJy/beam.
We thank CSIRO staff for rapidly scheduling and supporting these
observations.
