Abstract A measurement of the reduced double differential cross section $\tilde{\sigma}(x,Q^2)$ is presented for the neutral current process, $ep$, at high $0.9>y>0.63$ and intermediate $1000>Q^2>60$~GeV$^2$ range. The cross section measurement uses complete HERA-II data set and represents about twofold improvement in precision compared to the previous H1 publication. The high $y$ cross section is sensitive to the proton structure functions $F_2$ and $F_L$ and thus provides additional constraint on the gluon density function.
