Abstract I will report on X-ray (Chandra) and optical spectroscopic (WIYN) observations of the radio/H-alpha shell near the microquasar Cygnus X-1. The X-ray non-detection and the optical integral field spectra place upper limits on the velocity of the shock, the mass flow rate across the shock, and the temperature and density of the post-shock material, using robust line diagnostics and more sophisticated shock modeling. These limits enable us to derive a robust upper limit for the jet power. This work complements previous weaker limits from X-rays and narrow band imaging. The observations cannot rule out contributions from the O-star wind and radiation field to the evolution of the bubble, further limiting the jet power of Cygnus X-1.
