Abstract: We consider an elliptic curve $E_{\alpha,\beta}$ given by the equation $Y^2=X^3+\alpha X+\beta$, where $\alpha,\beta$ are real numbers, and look for integer points close to the curve. In case the diophantine type of $\alpha$ is larger than 4 we find infinitely many integer points unusually close to $E_{\alpha,\beta}$ or to the curve $E_{-\alpha,\beta}$.
