We conduct a survey of satellite galaxies around the nearby spiral NGC 4258 by combining spectroscopic observations from the Apache Point Observatory 3.5-meter telescope with SDSS spectra .
New spectroscopy is obtained for 15 galaxies .
Of the 47 observed objects , we categorize 8 of them as probable satellites , 8 as possible satellites , and 17 as unlikely to be satellites .
We do not speculate on the membership of the remaining 14 galaxies due to a lack of velocity and distance information .
Radially integrating our best fit NFW profile for NGC 4258 yields a total mass of 1.8 \times 10 ^ { 12 } M _ { \odot } within 200 kpc .
We find that the angular distribution of the satellites appears to be random , and not preferentially aligned with the disk of NGC 4258 .
In addition , many of the probable satellite galaxies have blue u - r colors and appear to be star-forming irregulars in SDSS images ; this stands in contrast to the low number of blue satellites in the Milky Way and M31 systems at comparable distances .
