Measurements of deeply virtual Compton scattering (DVCS) made at HERMES using 27.6 GeV e^± beams and various internal polarized or unpolarized gaseous targets are discussed. Results are reported on the transverse target-spin asymmetry (TTSA) associated with DVCS, extracted from data accumulated in 2002-2004 with the e+ beam on a transversely polarized hydrogen target. TTSA amplitudes leading in twist and αS are given as a function of -t, xB and Q2 in the kinematic range |t|<0.7 GeV2, 0.03
