Sections of the HIRES spectrum of the B3 star BD+65°1638 centered near Hα (left) and Hβ (right). The spectrum reveals weak evidence for possible emission reversal within the core of the Hα absorption feature with a radial velocity of ∼−25.8 km s−1, consistent with that of the molecular cloud. Otherwise the spectrum of BD+65°1638 is quite unremarkable in contrast to those of the classical Be star BD+65°1637 and the Herbig Be star LkHα 234.
