-* Other BRC options - we had considered BRC 31, 36, 38. BRC 31 is already thoroughly done (Rebull et al. 2011). BRC 34 (which the 2011 group did), BRC 36 and BRC 38 are all close to IC1396, another region I'm studying with another project. BRC 36 is in the region likely to be done to death. Our notes from a year ago say that the Spitzer data for BRC 38 are done, but I can't find the paper. We could start again from the entire BRC list and sort again? See figure below for context. The big square is someone else's (published) thesis data. The big blobby thing next to BRC 36 is [http://www.spitzer.caltech.edu/images/1058-ssc2003-06b-Dark-Globule-in-IC-1396 this], also done to death. We are also monitoring this region for changes in the stars. But BRC 38 may be a good one, or the larger context around BRC 34 or 38 (with WISE) would also work.

Not. R. Astron. Soc., 408, 157-169] identifies candidates for triggered star-formation in the SFO BRCs. Their list is SFO 1, 5, 7, 11E, 12, 13, 14, 25, 30, 31, 35, 36, 37, 38, 41, 42, 43, 44]. The argument is summarized in the abstract as follows:
		+
		+	"These observations confirm the presence of dense gas towards IRAS point sources detected at submillimetre wavelengths. Derived physical properties allow us to refine the sample of bright-rimmed clouds into those likely to be sites of star formation, triggered via the process of radiatively driven implosion. An investigation of the physical properties of our sources shows that triggered sources are host to greater turbulent velocity dispersions, likely indicative of shock motions within the cloud material. These may be attributed to the passage of triggered shocks or simply the association of outflow activity with the sources."

		+	So, one approach we could take is all of the BRCs in a region (e.g., ic1396/Tr37 region, or Gum nebula region), but this seems like biting off more than we can chew.
		+
		+	We could do brc 27+24 plus one other, i think, if y'all are motivated. Just need to pick the 3rd. Could be another one in the Tr37 region, or one of the ones tagged "maybe a good target" above.
