This note should be seen as a appendum to the work of E. Kowalski and the second author [KM1] and deals with the problem of bounding unconditionnally the order of vanishing at the critical point in a family of L functions. This problem is illustrated in the particular case of L functions of weight 2 primitive modular forms of prime level. Recall the notations from [KM1]: for q a prime number, let S2(q) be the set of primitive forms of weight 2 and level q, normalized so that their first fourier coefficient is 1; for
