Otero, Sebastian Alberto
The 2MASS star previously identified as T Boo by GCVS/VSX was the K3-5 dwarf "candidate 1" in Downes and Szkody. Current position is based on original coordinates and no optical candidate brighter than mag. 20.4 is seen there. Downes (2001) gives a different position (14 14 06.00 +19 03 54.0 (J2000.0), no visible candidate either) with the following note: "
1990AJ....100..540S
note that the spectrum of candidate 2 of Downes, R.A. and Szkody, P. (1989, AJ, 97, 1729) is quite red, while the spectrum of candidate 5 is a featureless, blue continuum. 1996-14S also observed candidates 2 and 5, and found object 2 to be a K5-M4 star, while object 5 is that of an F2-9 star; candidate 1 was found to be a K3-5 dwarf".

No star has been identified as the variable but the position has been changed according to a new GCVS revision that matches SIMBAD's position too.

Primary record creation. GCVS identification kept. 2MASS position.
Downes (2001) gives a different position with the following note: "1990-29 note that the spectrum of candidate 2 of Downes, R.A. and Szkody, P. (1989, AJ, 97, 1729) is quite red, while the spectrum of candidate 5 is a featureless, blue continuum. 1996-14S also observed candidates 2 and 5, and found object 2 to be a K5-M4 star, while object 5 is that of an F2-9 star; candidate 1 was found to be a K3-5 dwarf".
