V3890 Sagittarii

K. Sekiguchi, South African Astronomical Observatory reports: "The spectral evolution of V3890 Sgr has been monitored using the 1.9-m telescope at Sutherland since May 5. The overall development of the spectrum closely resembles that of the 1985 outburst of RS Oph. The red-region spectrum (range 560-760 nm, resolution about 0.35 nm FWHM) taken on June 22 shows the emerging TiO bands of an M4 III star. Strong coronal Fe VII 608.6-nm emission, which was absent on May 14 (IAUC 5015), and the Fe X 637.4-nm line are present. The star at the Duerbeck and Williams positions (6" east and 10" north of V3890 Sgr) was also observed. No detectable emission line was seen in its spectrum. This suggests that the star observed by Williams (1983, Ap.J. Suppl. 53, 523) was in fact V3890 Sgr = N Sgr 1962 in quiescent state and that his finding chart was incorrect."
