TITLE: GCN CIRCULAR NUMBER: 45019 SUBJECT: GRB 260614B: EP-FXT follow-up observation DATE: 26/06/22 22:10:22 GMT FROM: SVOM_group <svomgroup@bao.ac.cn> M. Pillas (IAP), A. Saccardi (CEA/Irfu), Ziming Wang (PKU), report on behalf of the SVOM and EP collaborations: EP-FXT performed a follow-up observation of GRB 260614B detected by SVOM/ECLAIRs (Godet et al., GCN 44938). The follow-up observation started on 2026-06-15 at 15:05:04 (UTC), about 25.3 hr after the SVOM trigger, with a total exposure time of 4 ks. On-ground analysis of the FXT data found an uncatalogued source within the ECLAIRs and MXT error circles at R.A., Dec. = 353.9080, -54.1164 deg (J2000) with an uncertainty of about 10 arcsec (radius, 90% C.L. statistical and systematic). This position is consistent with the optical counterpart (Palmerio et al., GCN 44939; Li et al., GCN 44943). The derived average unabsorbed flux is (1.64 +/- 0.25) x 10^(-13) erg/s/cm^2 (0.5-10 keV; 1-sigma uncertainty). Launched on January 9, 2024, EP is a space X-ray observatory to monitor the soft X-ray sky with X-ray follow-up capability (Yuan et al. 2022, Handbook of X-ray and Gamma-ray Astrophysics).
