The spectral investigations by Karachentsev et al. determined a radial velocity of 692 +/- 58 km/s for this object. Due tue the fact that the radial velocity of NGC 891 is mentioned with about 526 km/s, the dwarf [TT2009] 25 is now confirmed as NGC 891 dwA.
(Have also a look into the publication “New radial velocities for dwarf galaxies in the Local Volume, Karachentsev et al, 2015)
