Field of SGAS J0033+02 observed with HST in the optical (F814W) and near-infrared (F105W and F140W) bands. The gravitational arc formed by the lensed galaxy at z ≃ 2.39 (called ‘the Arc’) and its counter-images (‘Ci1’ and ‘Ci2’) are indicated. The bluish object located $7\stackrel{″}{.}3$ southwest of the arc is a Galactic star. The main absorbing galaxy at z ≃ 1.17, labelled ‘G1’, is shown along with its closest two companions at the same redshift: ‘G2’ to the northeast, and ‘G3’ to the west. Redshifts for these and additional sources at z > 1.16 are indicated next to each label.
