We present a survey of over 350 bright points from archival SOHO data. Extreme ultraviolet images were measured to determine orientation, length, and brightness in the EIT 171 angstrom (Fe X, 1 MK) and 195 angstrom (Fe XII, 1.5 MK) passbands. MDI data were analyzed to obtain the size, orientation, and magnetic flux of the corresponding magnetic bipoles. The three-dimensional reconnection theory of Longcope (1998) makes several predictions that may be tested with these data. For this, the first phase of the study, we concentrate on the scaling of EUV brightness with magnetic flux and the distribution of displacement angles between EUV bright points and their magnetic counterparts. We also verify the assumption of Longcope & Kankelborg (1999) that the distribution of magnetic orientations is random and independent of latitude.
