Wu (NAOC)\nreport on behalf of the SVOM/ECLAIRs team: \n\nUsing the event-by-event data downloaded through the X-band ground station, we report further analysis of SVOM/ECLAIRs observations of the possible faint burst GRB 260807A (SVOM burst-id sb26080703, GCN 45308, trigger time T0 = 2025-08-07T11:00:20 UTC). \n\nThe burst that triggered ECLAIRs shows a multiple peak light curve, and is detected from T0-20 s to T0  in the 8-120 keV energy band. \n\nThe time-averaged spectrum from T0-20 s to T0 in the 8-120 keV is well fitted by a power-law model with a photon index of 0.7+/-0.3 and a corresponding 4-120 keV fluence of (1.4+/-0.3)e-6 erg/cm^2.\n \nAll the quoted errors are at the 68% confidence level.\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. ECLAIRs was developed jointly by CNES, CEA-IRFU, CNRS-IRAP, CNRS-APC.\n\nThe SVOM/ECLAIRs point of contact for this burst is: Hui Yang (IRAP) (hui.yang@cnrs.fr). \n",
