1 Otero, Sebastian Alberto Ic range 13.71 - 12.78. Semiregular variations but the object is not bright in the infrared (J= 11.26; J-K= 1.03; V-Ic= 2.03).
2 Schmeer, Patrick Gaia DR2 parallax 0.1893 ± 0.0420 mas (distance 5.3 +/- ~1.5 kpc). The microlensing event TCP J18010186-2951258 was discovered by Tadashi Kojima on 2018 July 13.494 UT at mag. 10.8 CR. The ASAS-SN Sky Patrol observed a peak brightness of Vmag. 10.72 on 2018 July 14.113 UT. Identification based on K. Itagaki's astrometry (R.A. 18h01m01.82s, Decl. -29°51'24.7" (J2000.0)).
3 Schmeer, Patrick Discovered by T. Kojima on 2018 July 13.494 UT at mag. 10.8 CR (unfiltered).
