Abstract: We present preliminary results in an ongoing, comprehensive investigation of the star formation activity in LDN 1340. This dark nebula (opacity class 5) is located approximately 600 pc away, in the constellation Cassiopeia. Due to various reflection nebulae and a significant number of embedded IRAS sources, it was identified as a highly active intermediate mass star-forming region by Kun et al., 1994. Submillimeter maps, at 450 and 850 microns, of a portion of the L1340 cloud (L1340B) were obtained with the SCUBA bolometer array on the James Clerk Maxwell Telescope located on Mauna Kea, Hawaii. We have observed more than two dozen submillimeter sources in a ~17' by 12' region, many of them undetected at any other wavelength. A few of them are associated with previously identified IRAS or 2MASS sources. We have also mapped much of the region in the emission from the J=3-2 transition of CO. In this poster, we will discuss the evidence for triggered star formation within this cloud, based on dust continuum, CO, 2MASS and other data.
