We determine explicitly the foliated cohomology $ H_ {\cal F}^\ast (M) $ of the affine Reeb
flow ${\cal F} $ on the Hopf manifold ${\Bbb S}^ n\times {\Bbb S}^ 1$. The vector space $ H_
{\cal F}^ 1 (M) $ contains exactly the obstructions to solve the cohomological equation $
X\cdot f= g $ where $ f $ and $ g $ are $ C^\infty $-functions and $ X $ is any non singular
vector field defining the foliation ${\cal F} $. The topological dual of $ H_ {\cal F}^ 1 (M) $ is
the space of distributions invariant by $ X $.
