1 Otero, Sebastian Alberto No eclipses in ASAS-SN data for the star at 10 42 47.78 -59 04 17.7 (J2000.0) between 2016 and 2020. Period 365 d. in the GCVS looks unlikely or the identification is still incorrect.
2 Schmeer, Patrick Gaia DR2 parallax 0.7538 ± 0.0237 mas (distance 1279 ± 40 pc).
3 Otero, Sebastian Alberto J-K= 0.40; B-V= 0.71. Only a single fading event recorded on 1922 May 20.
4 Otero, Sebastian Alberto GCVS remark (2011/09): The variable star's identification with the source catalog is uncertain
