We classify, up to isomorphism, elliptic surfaces with irregularity one having exactly one singular fiber (necessarily of typeI6*). All of them turn out to be elliptic modular surfaces (Shioda [11]), so that the problem is indirectly equivalent to classifying certain subgroups ofSL2(Z). These surfaces are then used to produce examples of (elliptic) surfaces withq=1, anypg≥1, which have maximal Picard number (see Persson [7] for the caseq=0). Finally, the classification yields some interesting relationships between hypergeometric functions, theta functions, and certain automorphic forms.
