Observations at 80- and 130-microns have revealed a source of far-infrared emission in the Cep F portion of the Cepheus OB3 molecular cloud. Molecular line measurements of this region, at the CO J = 1-0 line frequency, have led to the discovery of two CO maxima. One of these coincides with the new far-infrared source. The other is at least as intense as Cep B, until now considered to be the hottest part of the cloud. There is some evidence to suggest that a second far-infrared source is associated with this hotspot. If the far-infrared emission results from the presence of embedded protostars, their location relative to the OB association stars and to the other active region, Cep A, requires a reexamination of how stars form in the Cepheus OB3 association.
