Abstract (from CDS):

We present the discovery of a faint, resolved stellar system, BLISS J0321+0438 (BLISS 1), found in Dark Energy Camera data from the first observing run of the Blanco Imaging of the Southern Sky (BLISS) survey. BLISS J0321+0438 (BLISS 1) is located at (α20002000)=(177○ / . 511,-41○ / . 772) with a heliocentric distance of D=23.7–1.0+1.9kpc. It is a faint, MV=0.0–0.7+1.7mag, and compact, rh=4.1–1+1pc, system consistent with previously discovered faint halo star clusters. Using data from the second data release of the Gaia satellite, we measure a proper motion of (µαcosδ,µδ)=(-2.37±0.06,0.16±0.04) mas yr–1. Combining the available positional and velocity information with simulations of the accreted satellite population of the Large Magellanic Cloud (LMC), we find that it is unlikely that BLISS J0321+0438 (BLISS 1) originated with the LMC.
