  We report evidence of magnetic reconnection in the transition region of the
terrestrial bow shock when the angle between the shock normal and the immediate
upstream magnetic field is 65 degrees. An ion-skin-depth-scale current sheet
exhibits the Hall current and field pattern, electron outflow jet, and enhanced
energy conversion rate through the nonideal electric field, all consistent with
a reconnection diffusion region close to the X-line. In the diffusion region,
electrons are modulated by electromagnetic waves. An ion exhaust with energized
field-aligned ions and electron parallel heating are observed in the same shock
transition region. The energized ions are more separated from the inflowing
ions in velocity above the current sheet than below, possibly due to the shear
flow between the two inflow regions. The observation suggests that magnetic
reconnection may contribute to shock energy dissipation.
