The infrared bolometric luminosity of the extended infrared emission from the L1551 flow is estimated as 19 (−4 +10) L⊙. Ultraviolet radiation from the shock associated with the flow appears to heat the surrounding dust. The extended infrared emission raises the total energy requirement for the flow over a 10^4 year lifetime to 10^46–47 ergs. If gravitational in origin, this energy likely originates from a region <10^13 cm. Infrared radiation offers a new probe for interstellar shocks by sampling the ultraviolet halo surrounding the shock.
