Abstract: There are few good direct laboratory tests of boost invariance for electrons,because the experiments required often involve repeated precision measurementsperformed at different times of year. However, existing measurements andremeasurements of the 2S-1S two-photon transition frequency in H-which weredone to search for a time variation in the fine structure constant-alsoconstitute a measurement of the boost symmetry violation parameter 0.83c TX +0.51c TY + 0.22c TZ = 4 +- 8 x 10^-11. This is an eight order ofmagnitude improvement over preexisting laboratory bounds, and with only oneadditional measurements, this system could yield a second comparableconstraint.
