The Distance to the Galaxy Coma P
  If the extremely low surface brightness galaxy Coma P lies at $5.5\pm0.3$ Mpc
as recently proposed then it would have an extraordinarily deviant peculiar
velocity of $\sim900$ km $\mathrm{s^{-1}}$ at a location where differential
velocities between galaxies are low. We have accessed the images from the HST
archives used to derive the literature distance from the magnitude of the tip
of the red giant branch. Our analysis gives the distance to be $10.9\pm1.0$
Mpc. At this location the galaxy lies within the infall region of the Virgo
Cluster, such that its still considerable peculiar velocity of $\sim500$ km
$\mathrm{s^{-1}}$ is consistent with an established model. Coma P has an
unusually pronounced asymptotic giant branch relative to its red giant branch.
The dominant stellar population is just a few Gyr old.
