1 Otero, Sebastian Alberto VSP Note: 17.2 Vmag. star 10" to the ESE.
2 Otero, Sebastian Alberto Several outbursts recorded by AAVSO observers. 0.1 mag. modulation detected by Gordon Garradd during an outburst in 2000 (vsnet-alert 4238).
3 Otero, Sebastian Alberto Originally classified as an UG-type star. The M: classification is wrong. No red star in 2MASS in this area. USNO archive R and B plates show the star is rather blue (B= 18.3; R= 18.3). Only one outburst (R= 15.9) on JD 2445787.
