Fluxes in Ly-alpha and H-alpha lines from Proto Globular Clusters (PGCs) at redshifts z>1 are estimated. Two possible sources are considered: HII regions and supernovae remnats in PGCs. Intensities in Ly α and H α lines are calculated. It is shown that such PGCs can be detectable for the ongoing and future projects (VLTI, NGST).
