The following trigger information was received on the ground with low latency by the SVOM VHF Alert Network.\n\nThe burst was detected by the Image Trigger (IMT), from which we received a sequence of 4 alerts. At the time of reception, IMT provided the alert with the best signal-to-noise-ratio in the image (SNR) of 13.84 in the [8-120] keV energy band over a time window of 40.96 seconds starting at 2026-11-14T09:32:53. Note that at least 25 alerts were generated but only 4 have been received.\n\nThe localization of the best alert is R.A., Dec. 345.8973, -32.3702 degrees:\nR.A. (J2000) = 23h03m35.35s\nDec. (J2000) = -32d22m12.60s\n with a 90% confidence level (C.L.) radius of 5.91 arcmin (including systematic error of 2 arcmin added in quadrature).\n\nThe SVOM/ECLAIRs light curve showed a single broad peak structure with a T90 duration of about 46 -9 / +6 s.\n\nSVOM slewed to the burst. SVOM/MXT began observing the field after the slew. Using onboard processed data, no X-ray source was detected with MXT.\nVT began observing the field after the slew. The analysis of the data will be published in a future circular.\n\nThe Space-based multi-band astronomical 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. SVOM/ECLAIRs was developed jointly by CNES, CEA-IRFU, CNRS-IRAP, CNRS-APC. SVOM/GRM was developed by the Institute of High Energy Physics (IHEP) of CAS. SVOM/MXT was developed jointly by CNES, CEA-IRFU, CNRS-IJCLab, University of Leicester, MPE.\n\nThe Burst Advocate (BA) on shift for this alert is Wenjin XIE: xiewj@bao.ac.cn.\nPlease contact the BA by email if you require additional information.\n",
