Close the aperture? (I suppose flare is bigger a problem with bigger apertures, as the peripheral part of the lens contributes more to the image).
Remove the "protection UV filter" if one is present. They do add flare, in dire conditions especially.
If you work with a tripod, project a shade on the lens with your hand (or whatever) in such a way that the hand is not in the picture but the shade falls on the lens.
