[vsnet-alert 10124] NSV18024 = HD 74771 spectrum by Fujii-san

   Fujii-san reported the following spectrum of HD 74771 = NSV18024
on Apr. 26.

   No emergence of strong emission lines was detected, possibly
ruling out a flare-type event of a G8 star.

   The apparent absence of emission lines is consistent with
the supposed dwarf nova-type outburst (of a companion?), though
the outburst may have been almost over at the time of Fujii-san's
observation.
