Abstract. We explore the structures immediately surrounding the high-mass young stellar object S140 IRS 3
within the L1204 molecular cloud. We have obtained a bispectrum speckle interferometric K-band image with a
resolution of 150 mas and a seeing-limited molecular hydrogen line emission image of IRS3. Our speckle image
resolves IRS 3 into three point sources, a close binary with separation 0.63 and a third component 1.3 away.
