We observed the Fast X-ray Transient EP241021a discovered by Einstein Probe (Hu et al. GCN 37834; Wang et al. GCN 37848) at the optical counterpart position (Fu et al. 37840) with the Australia Telescope Compact Array at 5.5 and 9 GHz in continuum mode on Oct 29th 11:00-18:00 UT (i.e. 8.40 days after the EP trigger) under four independent projects.
A bright source was detected at 5.5 GHz with with a flux density of 400 +/- 20 microJy
at the OT position. The rms noise in the final map is 13 microJy/beam.
Further observations are planned.
The observers thank the ATCA staff for promptly scheduling the observations.
