| contents | We use the Burgess bound and Selberg sieve to obtain an upper bound on the second moment of sums over an interval $[u+1,u+h]$ of Legendre symbols modulo primes $p$ in a dyadic interval $[Q,2Q]$. The bound is nontrivial and gives a power saving with respect to $h$ for any $u \le Q$, provided $h \ge ψ(Q)$ for any function $ψ(Q)\to\infty$ as $Q\to\infty$. This can be viewed as a generalisation of a result of D. R. Heath-Brown (1995) on moments of sums or quadratic characters over the initial interval $[1,h]$. |
