How these objects distribute through a galaxy sheds light on the galaxy star formation rate and history, mass distribution, and dynamics. The nearby galaxy M33 is an excellent place to study the distribution of H{alpha}-bright point sources in a flocculant spiral galaxy. We have reprocessed an archived WIYN continuum-subtracted H{alpha} image of the inner 6.5'x6.5' of M33 and, employing both eye and machine searches, have tabulated sources with a flux greater than approximately 10^-15^ erg/cm^2^/s. We have effectively recovered previously mapped H II regions and have identified 152 unresolved point sources and 122 marginally resolved compact sources, of which 39 have not been previously identified in any archive. An additional 99 H{alpha} sources were found to have sufficient archival flux values to generate a Spectral Energy Distribution. Using the SED, flux values, H{alpha} flux value, and compactness, we classified 67 of these sources.2017AJ....154..268Mhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/154/268CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toVII/233 : The 2MASS Extended sources (IPAC/UMass, 2003-2006)B/gcvs : General Catalogue of Variable Stars (Samus+, 2007-2017)II/340 : XMM-OM Serendipitous Source Survey Catalogue (XMM-SUSS2.1)J/ApJS/89/85 : Blue and red supergiants in M33 (Ivanov+ 1993)J/AJ/110/1649 : VI photometry near the M33 nucleus (Mighell+ 1995)J/AJ/110/2739 : H-alpha emitting regions in M33 (Calzetti+ 1995)J/ApJ/469/629 : UV-brightest stars of M33 and its nucleus (Massey+ 1996)J/ApJ/505/793 : New WR star in M33 (Massey+, 1998)J/A+AS/140/309 : Blue-H{alpha} objects in M33 (Fabrika+, 1999)J/ApJS/120/247 : Supernova remnants in M33 (Gordon+, 1999)J/PASP/111/685 : HII regions of M33.
