  X-ray polarimetry of solar flares is still a not well established field of
observation of our star. Past polarimeters were not able to measure with a high
significance the polarization in X-rays from solar flares. Moreover, they had
no imaging capabilities and measured only the polarization by integrating on
all the image of the source. We propose a mission concept based on a gas
photoelectric polarimeter, coupled with multilayer lobster-eye optics, to
perform imaging-spectro-polarimetry of solar flares while monitoring the entire
solar disc.
