Report on behalf of the SVOM team:

MXT observed the field fo GRB241002C (Schanne et al., GCN 37674) as a TOO from 2024 October 3rd  at 02:29 UTC to 05:53 UTC, 17 hours after T0.

A faint source is detected by the on board software at RA: 62.410 Dec =- 7.896  with a 90% c.l. error of 1 arc minute. Further results will be given once the full telemetry is received and analyzed.

We note that the position of 1RXS J040940.8-075327 (V* EI Eri) is compatible with the MXT error box. Further observations will be needed to assess the variability of the source. Observations by other X-ray telescopes are encouraged.

The Space Variable Objects Monitor (SVOM) is a China-France joint mission led by the Chinese National Space Administration (CNSA), French Space Agency (CNES), and the Chinese Academy of Sciences (CAS), which is dedicated to observing gamma-ray bursts and other transient phenomena in the energetic universe. MXT was developed jointly by CEA, CNES, University of Leicester, IJCLab and MPE.
