We present a photometric search for UCD candidates in the nearby galaxy groupNGC 1023 (d=11 Mpc) -- the poorest environment searched for UCDs yet --, basedon wide field imaging with CFHT. After photometric and morphological selection,we obtain a sample of 21 UCD candidates with -12<M_V<-11 mag, if located at NGC1023's distance. From spectroscopy taken at Calar Alto observatory, we identifythe UCD candidate in closest projection to NGC 1023 as an emission linebackground galaxy. Our photometric data show that in the NGC 1023 group, themass spectrum of analogs to Fornax/Virgo UCD is restricted to about 1/4 of themaximum Fornax/Virgo UCD mass. More spectroscopy is needed to further constrainthe mass range of UCDs in this galaxy group.Comment: 5 pages, 4 figures, to appear in the proceedings of ESO Astrophysics  Symposia: "Groups of Galaxies in the Nearby Universe", eds.
