11899 2022-02-13 14:30:24 Robin Leadbeater Robin Leadbeater None Other 0 1 The spectrum is of a mid B type star at ~zero redshift, (consistent with the B4IV/V classification for HD58859 given in SIMBAD) with H alpha in emission. The original classification spectrum is therefore likely to be incorrect. (Perhaps the nearby F star BD-02 2115 at similar brightness ?) Follow up at higher resolution is suggested. 2022TNSCR.388....1L
