  We present time-series Doppler images of the rapidly-rotating active binary
star EI Eri from spectroscopic observations collected during the MUSICOS
multi-site campaign in 1998, since the critical rotation period of 1.947 days
makes it impossible to obtain time-resolved images from a single site. From the
surface reconstructions a weak solar-type differential rotation, as well as a
tiny poleward meridional flow are measured.
