The prior reporting of the magnitudes of EP260602a (Xu et al., GCN 44781) was affected by light blooming near the target. The corrected measurements are as below:
Mid time | Band | Exposure Time | Brightness
9.49 h VT_B 93*50 s 22.7 +/- 0.2 mag
9.51 h VT_R 84*50 s 21.5 +/- 0.1 mag
The measurements are in the AB magnitude without correction for Galactic extinction:
We apologize for the errors, and gratefully acknowledge the critical support from the COLIBRÍ team in identifying this discrepancy (Watson et al., GCN 44790).
