The number of such magnetic white dwarfs known is now some hundreds. Fields range in strength from a few kG to several hundred MG. Almost all the known magnetic white dwarfs have a mean field modulus >= 1 MG. We are trying to fill a major gap in observational knowledge at the low field limit (<= 200 kG) using circular spectro-polarimetry.\n  In this paper we report the discovery and monitoring of strong, periodic magnetic variability in two previously discovered \"super-weak field\" magnetic white dwarfs, WD2047+372 and WD2359-434.
