1 Otero, Sebastian Alberto Eclipses discovered visually by Rod Stubbings. Standstill between HJD 2459698 and 2459713.
2 Otero, Sebastian Alberto ASAS-SN and APASS magnitudes contaminated by 2MASS J17024665-3440214 (V= 16.2; sep. 7"). Range has been corrected.
3 Otero, Sebastian Alberto The ASAS light curve at this position is actually for the brighter and redder star (J-K 0.90) 2MASS J17024526-3440590. Colors of this star are consistent with the K5II spectrum published in IBVS 3716. Maybe they took spectra of the wrong star? The ~3 mag. change in one night suggests the UG nature might be okay and the blue object reported in 2001A&A...373..608D seems to support that.
4 Otero, Sebastian Alberto Symbiotic? Spectral type not consistent with UG. However, the report of a change of ~3 mag. in one night (IBVS 3716) is doubtful. J-K 0.68 is not particularly red and the same star appears in the Blue stellar candidates list in 2001A&A...373..608D with V= 15.94 and u-v= -0.39.
