  We report on an archival X-ray observation of the eclipsing RS CVn binary XY
UMa ($\rm P_{orb}\approx$ 0.48d). In two $\emph{Chandra}$ ACIS observations
spanning 200 ks and almost five orbital periods, three flares occurred. We find
no evidence for eclipses in the X-ray flux. The flares took place around times
of primary eclipse, with one flare occurring shortly ($<0.125\rm P_{orb}$)
after a primary eclipse, and the other two happening shortly ($<0.05\rm
P_{orb}$) before a primary eclipse. Two flares occurred within roughly one
orbital period ($\Delta \phi\approx1.024\rm P_{orb}$) of each other. We analyze
the light curve and spectra of the system, and investigate coronal length
scales both during quiescence and during flares, as well as the timing of the
flares. We explore the possibility that the flares are orbit-induced by
introducing a small orbital eccentricity, which is quite challenging for this
close binary.
