We are continuing to study the observational characteristics of Holoea. This young stellar object, associated with IRAS 05327+3404, appears to be undergoing the quick transition from embedded (Class I) to exposed (Class II) T Tauri star. We have obtained new observations of this source, particularly pertaining to the outflow and the characteristics of the dust. We will present some of our new observations and discuss some of the implications. Comparisons of visible and near-IR (JHK) images show a morphology which changes significantly with wavelength. Our low-resolution optical spectra show the presence of extended red emission (ERE) in the tail-like reflection nebula. We will also present images in the CO(2-1) line made with the JCMT. Observations of Holoea tell us about the characteristics of the very small class of objects in this short transitional stage.
