  We consider a two component hybrid inflation model, in which two fields drive
inflation. Our results show that this model generates an observable
non-gaussian contribution to the curvature spectrum, within the limits allowed
by the recent WMAP year 3 data. We show that if one field has a mass less than
zero, and an initial field value less than 0.06Mpl while the other field has a
mass greater than zero, and initial field value ranging between 0.5Mpl and Mpl
then the non-gaussianity is observable with 1<fnl<1.5, but that fnl becomes
much less than the observable limit should we take both masses to have the same
sign, or if we loosened the constraints on the initial field values.
