Abstract
As part of a deep near-infrared imaging survey for infrared point sour ces in Bok globules, we have discovered the first Bok globule showing evidence of harboring an aggregate of embedded objects. By the use of a near-infrared color-color diagram, a total of 12 objects seen toward this globule were found to exhibit near-infrared color excess consist ent with those of young stellar objects having intrinsic infrared exce ss emission due to circumstellar material. Four of these objects exhib it extended infrared emission similar to that seen surrounding other y oung stellar objects in Bok globules. The objects are contained in a r egion of about 3 arcmin2 estimated to correspond to about 0.1 pc2. Tog ether, these facts indicate that this group of stars forms an aggregat e of young stellar objects contained in the globule.
