NOAO Survey program call

The new call for NOAO [NSF OIR Lab] Survey proposals, and DECam in particular, is now out:

"The completion in the 2018B semester of observations for the Dark Energy Survey (DES) and DECam Legacy Survey (DECaLS) will open up approximately 125 additional nights per year on the Blanco telescope starting in 2019. Since the Dark Energy Camera (DECam) is a survey machine par excellence, we intend to allocate a substantial fraction of available DECam time to new survey programs. "

I wonder if there is value in any precursor survey data for LSST SMWLV. Proper motion data would, for example, be greatly enhanced for (the brighter) sources in the early years of the survey. Any ideas that we should pursue as a collaboration?

Best wishes,
John
