We observed the field of the fast X-ray transient EP241107a (Zhou et al., GCN 38112) with Karl G. Jansky Very Large Array (VLA) under the DDT (PI: A. Balasubramanian, 24B-492) on 1st December 2024 in band C (6 GHz) for about 30 minutes starting at 00:38 hours UTC.
We detect a point radio source at 02h20m02.4s +03d20m01.6s. We used 3C147 for the flux calibration and J0239-025 for complex gain and phase calibration. The CASA-VLA calibration and imagining pipeline 6.5.4.9 was used for data calibration and imaging. We compute the flux density of the radio source to be 207±7 µJy. There is no previously reported source in the radio catalogues at the position of this source.
We thank the TAC and operations team of VLA for making these observations possible. The National Radio Astronomy Observatory is a facility of the National Science Foundation operated under cooperative agreement by Associated Universities, Inc.
