Polarized intensity maps of W Hya observed with SPHERE-ZIMPOL. The top and bottom rows show the data of W Hya obtained on 2015 July 8 (phase 0.92, Paper I) and on 2016 March 23 (phase 0.54), respectively. The observed images at 645 nm (CntHa, continuum), 656.3 nm (NHa, Hα), 717 nm (TiO717, TiO band), 748 nm (Cnt748, continuum), and 820 nm (Cnt820, continuum) are shown from the left to the right. North is up, east to the left in all panels. The 2016 data reveal the formation of a new, small dust clump in the west, while the dust clump detected in the SW in 2015 disappeared in 2016. The polarized intensity is shown in units of W m^-2μm^-1 arcsec^-2. The circles in the leftmost panels represent the size of the star measured in the continuum near 2.3 μm based on our VLTI/AMBER observations.
