EP240416A: Khureltogoot optical upper limit
Abstract
We observed the EP240416A (Cheng et al., GCN 36138) with the ORI-40 telescope of Khureltogoot observatory in Clear filter starting on 2024-04-16 (UT) 17:57:07. We did not detect the optical counterpart (Chen et al., GCN 36139; An et al., GCN 36144). Preliminary photometry of a stacked image is the following Date UT start t-T0 Exp. Filter OT Err. UL(3sigma) (mid, days) (s) 2024-04-16 17:57:07 0.65409 54*60 Clear n/d n/d 19.7 The photometry is based on nearby USNO-B1.0 (R2) stars. The given results is in agreement with the upper limit obtained by (Xiong et al., GCN 36155).
