Abstract
A new complex of infrared sources ~1' across has been discovered in Orion. Associated with this cluster is an extended ~6' molecular cloud producing intense CO emission. Its measured infrared luminosity is less than ~500 L_☉. The complex is hypothesized to be composed of pre-main-sequence sources. Several arguments suggest that these stars heat dust in the larger molecular cloud and thus cause the strong CO emission. The complex is not associated with a known visible or radio continuum feature, and searches over a 0.º7 X 0.º7 field show no other comparable unknown 2.2-μ sources.
