IRAS coadded survey data of a 1°×1° field centered on the dark cloud L1551 reveals extended 60 and 100 μm emission aligned with the axis of the collimated molecular outflow from IRS 5. The data suggest strongly that the infrared emission is associated with the outflow from IRS 5. The luminosity of the extended infrared emission is considerable, equalling 18% of the bolometric luminosity of IRS 5 itself. The distribution of the infrared surface brightness and the 60/100 μm color temperature is used to evaluate several possible mechanisms which might give rise to the observed emission.
