This paper reports a detailed multiwavelength data analysis of a low-mass BH hosted in the pseudobulge of UM 625. First noted as a “neutral compact spherical disc galaxy” by Zwicky et al. (1975), the blue color of UM 625 ($B-V=0.67$ mag; Salzer et al. 1989) placed it in early catalogs of blue compact galaxies (e.g., Campos-Aguilar et al. 1993). A high spatial resolution optical image was obtained with [*HST*]{} as part of the nearby AGN survey of Malkan et al. (1998), in which UM 625 was noted as an S0 galaxy with a partial nuclear ring structure. Later analysis of a near-infrared (NIR) [*HST*]{}/NICMOS image revealed a point-like nucleus embedded in an exponential surface brightness profile (Quillen et al. 2001; see also Hunt & Malkan 2004). An [*HST*]{} ACS/HRC image taken in the near-ultraviolet (NUV) shows a very bright, compact, yet partially resolved nucleus (Mu[ñ]{}oz Mar[í]{}n et al. 2007).

An optical spectrum of UM 625 was first acquired as part of the University of Michigan objective-prism survey for emission-line galaxies (MacAlpine & Williams 1981), from which its common name originates.
