  A scanning micro superconducting quantum interference device (microSQUID)
microscope is used to directly image vortices in a superconducting Al thin
film. We observe the temperature dependence of the vortex distribution in a
regular defect (hole) array patterned into the Al film. The first direct
observation of the localized superconducting state around the holes is shown as
well as the effect of the hole size on nucleation of the superconducting state.
