TITLE: GCN CIRCULAR NUMBER: 43709 SUBJECT: GRB 260211A: LCO optical upper limits DATE: 26/02/12 08:30:28 GMT FROM: SVOM_group <svomgroup@bao.ac.cn> C. Wu (NAOC), A. Saccardi (CEA/Irfu), D. Turpin (CEA/Irfu), D. Gotz (CEA/Irfu), D. Adrien (CEA/Irfu), report on behalf of the SVOM mission team: We observed the field of GRB 260211A (Gotz et al., GCN 43705) with the LCO 1-m telescope at Cerro Tololo Interamerican Observatory equipped with the Sinistro instrument. Our observation started on 2026-02-12 at 02:37:50 UT (about 7.22 hr after the trigger) and we obtained 3x200 s exposures in the SDSS r filter. In the stacked image, we do not detect any new source within the SVOM/ECLAIRs error box, in agreement with Globus et al. (GCN 43707). We measure the following upper limit calibrated against the UCAC4 catalog, and not corrected for Galactic extinction: r > 22.2 AB (5-sigma, mid-time 7.28 hr after the trigger). This project is funded by the SVOM collaboration.
