GRB 241206B: SVOM/MXT observations: a probable flare from the QSO 1ES 1959+650

SVOM/MXT observed the SVOM/ECLAIRs error box (Saccardi et al. GCN 38450) 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.
