Region around IRS 2 at 100 and 160 μm (left and right, respectively). Stars mark the location of known cluster members, labeled in green. G-85 and HBC 677 are clearly detected at 100 μm, but G-85 is only a marginal detection at 160 μm. Two small condensations to the north of IRS 2 are also apparent. The brightest one corresponds to G-122. The diameter of the IRS 2 ring is 27′′, corresponding to about 4600 AU. The condensations are about 10′′ in radius, or a diameter of ~ 3500 AU at 170 pc. Another disked object in the region, G-87, is not detected in either image.
