Otero, Sebastian Alberto

3.7 mag. (Ic) fading event in OGLE data around JD 2451000. The identifier ASAS J181706-2358.0 given in 2012arXiv1211.2475T only has spurious data caused by light contamination from nearby stars. The true star identifier is ASAS J181706-2357.8 and shows the star only visible at V= 13.5 around JD 2452100 (and also affected by light contamination). |
