  We observed a field in the disk of the LMC on two consecutive nights in
search of rapid variable stars. We have found two pulsating stars of type RRab
and delta Sct, and four binary stars, among the latter one sdB or CV below the
LMC blue Main Sequence and three very close binary systems on the MS. At least
one of the MS binaries, and possibly all three, are the first solar-type (W
UMa-type) contact binaries to be detected in any extragalactic system and
observed to obey the same Mv = Mv(log P, B-V) calibration as the Galactic
systems. Given the selection effects due to small amplitudes at faint
magnitudes, the frequency of such binaries in the disk of the LMC with its
large spread in population ages is not inconsistent with that in the disk of
our Galaxy, and contrasts with the lack of binaries found in earlier
observations of the much younger LMC cluster LW55.
