Near-infrared observation of two far-infrared sources in the W3 region: G133. 8+1. 4 (W3N) and G133. 982+1. 14 (BS4)
Observations from 1.2 to 21 ..mu..m show that G133.8+1.4 (W3N) and G133.982+1.141 (BS4) are weak near-infrared sources, in contrast to their far-infrared intensities. W3N appears to be a typical compact H II region, excited by a small cluster of OB stars; BS4 appears to be at an earlier evolutionary state and perhaps excited by a massive, pre-main sequence star. Both infrared sources appear associated with the giant molecular cloud in the W3/W4 region.
