Research Notes
Some Hubble studies performed using
the CMBR as the reference-frame for
galaxy velocities.  Heliocentric velocities
are relative to the sun, and there is still
the motion of the sun around the Milky
Way (about 225 km/s) and the motion of
the Milky Way.
Who will volunteer to do a short
presentation on the MAP and PLANCK
missions next week?
