TITLE: GCN CIRCULAR NUMBER: 44606 SUBJECT: EP260512a: EP-FXT follow-up observation DATE: 26/05/14 07:08:03 GMT FROM: EP Team at NAOC/CAS <ep_ta@bao.ac.cn> R. D. Liang, M. J. Liu (NAO, CAS), H. Z. Wu (HUST), H. Sun (NAO, CAS) on behalf of the Einstein Probe (EP) team: EP-FXT observed the field of EP260512a (detected by EP-WXT, Liang et al., GCN 44594; and followed by COLIBRÍ, Diego et al. GCN 44595, and MASTER-Net observations, Lipunov et al., GCN 44603) for 2.6 ks starting at 2026-05-13 10:06:08, around 25.6 hours after the detection by EP-WXT. No significant X-ray source is detected within the 2.6 arcmin radius of the EP-WXT position (Liang et al., GCN 44594) to a preliminary 0.5-10 keV upper limit of 7e-14 erg/cm^2/s. 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).
