SPHERE/IRDIS total intensity images of the disk at each epoch as reduced with the KLIP algorithm. The star is in the center of the images, and the epochs are ordered sequentially from the top to the bottom. The data are smoothed with a one-pixel Gaussian kernel except in June 2015, for which the smoothing is larger (two pixels). The field of view is 13′′ × 1.5′′, and the intensity scale is adapted for each epoch. The top and bottom axes are graduated every 0.5′′.
