The stars' speed can be measured using the Doppler shift of their color spectra.
The European Space Agency's Gaia observatory will soon have complete speed observations of 1% of our galaxy's stars. It will be able to directly see the orbital effects of dark matter if there are any.

Don't forget to find your own base movement speed during this time along with the are you moving away or towards.
