D. Götz (CEA/Irfu), N. Leroy (IJClab), M. Moita, H. Goto, C. Plasse (CEA Irfu), F. Robinet, C. Van Hove (IJCLab), P. Maggi (ObAS) report on behalf of the SVOM MXT Team.

SVOM/MXT observed the SVOM/ECLAIRs error box (Saccardi et al. GCN 38450Loading...
 
 ) as a TOO starting at 16:50 UT on December 6th 2024, i.e. 52 minutes after the ECLAIRs trigger.

The on-board software clearly detects a single persistent X-ray source at

RA = 300.013, 
DEC = 65.1563

with a R90 error of about 35 arc sec (90% c.l.).

This position is compatible with the one of the QSO 1ES 1959+650. We hence suggest that the ECLAIRs trigger is related to an outburst of this source and it is not a real GRB.
