We confirm that there are at least three separate low-latitude over-densities of blue F turnoff stars near the Milky Way anti-center : the Monoceros Ring , the Anti-Center Stream ( ACS ) , and the Eastern Banded Structure ( EBS ) .
There might also be a small number of normal thick disk stars at the same location .
The ACS is a tilted component that extends to higher Galactic latitude at lower Galactic longitude , 10 kpc from the Sun towards the anti-center .
It has a sharp cutoff on the high latitude side .
Distance , velocity , and proper motion measurements are consistent with previous orbit fits .
The mean metallicity is [ Fe/H ] = -0.96 \pm 0.03 , which is lower than the thick disk and Monoceros Ring .
The Monoceros Ring is a higher density substructure that is present at 15 \arcdeg < b < 22 \arcdeg at all longitudes probed in this survey .
The structure likely continues towards lower latitudes .
The distances are consistent with a constant distance from the Galactic Center of 17.6 kpc .
The mean line-of-sight velocity of the structure is consistent with a thick disk rotation .
However , the velocity dispersion of these stars is \sim 15 km s ^ { -1 } , and the metallicity is [ Fe/H ] = -0.80 \pm 0.01 .
Both of these quantities are lower than the canonical thick disk .
We suggest that this ring structure is likely different from the thick disk , though its association with the disk can not be definitively ruled out .
The Eastern Banded Structure ( EBS ) is detected primarily photometrically , near ( l,b ) = ( 225 \arcdeg, 30 \arcdeg ) , at a distance of 10.9 kpc from the Sun .
