1 Otero, Sebastian Alberto DENIS J181028.3-272958 (Ic= 13.47 on 2450189.909) is 1" to the East and is not recorded in other catalogues. It is not present in a deep OGLE-IV Ic image down to mag. 22.
2 Otero, Sebastian Alberto The recurrent nature seems doubtful due to the large amplitude.
3 Otero, Sebastian Alberto VSP Note: 15.7 mag. star 4" to the W.
