We present submillimeter and mid-IR images of the circumstellar disk around the nearby F2 V star η Corvi. The disk is resolved at 850 μm with a size of ~100 AU. At 450 μm the emission is found to be extended at all position angles, with significant elongation along a position angle of 130° ± 10°; at the highest resolution (9.″3), this emission is resolved into two peaks that are within the uncertainties offset symmetrically from the star at 100 AU projected separation. Modeling the appearance…
