TRACE is uniquely able to observe the birth and evolution of emerging flux regions, X-ray ``bright points" and bona-fide active regions due to its high spatial resolution, wide temperature coverage, and continual solar viewing. On board memory limitations and photon statistics, however, do force compromises. In this poster we discuss several cases of emerging flux and subsequent region evolution. These include events at different aspect angles (on disk and near the limb), near and not near existing active regions with which there can be interconnection, and regions that disappear in a couple of days as well as those which develop more fully. Some of the observations include several channels (temperature regimes) and some concentrate on higher temporal resolution with less spectral coverage. Analysis of some of the latter include MDI magnetograms at a one minute cadence. This work was supported by NASA contract NAS5-38099.
