Zielinski P., Wyrzykowski L., Lam M., Gezer I., Kruszynska K., Rybicki K.A., Ihanec N. (Warsaw University Astronomical Observatory, Poland), Zdanavicius J., Maskoliunas M., Pakstiene E. (Institute of Theoretical Physics and Astronomy, Vilnius University, Lithuania), Ismailov N.Z., Mikailov Kh.M., Khalilov O.V., Alekberov I.A., Bagirli S., Alishov S.A. (Shamakhy Astrophysical Observatory of National Academy of Sciences, Azerbaijan) report/s a classification of object: AT 2019nkr
Type: Other
Remarks: Spectral lines D Na I 5893 A (combined 5889+5896 A) visible, as well as Si I 5780 A, some Fe I lines, with blue displacement -25, -40 km/s. There are no emission lines and the shape of the continuum suggests reddened G8 III star, therefore it is likely a microlensing event.
The following Classification spectrum was provided:
