Movies of solar granulation frequently show bright granules that expand rapidly and reach sizes larger than an average granule. 

The data archive of the GREGOR infrared spectrograph (GRIS, Collados et al. 2012, AN 333, 872) is online now. GRIS data prior to 2017 is open access and now available through the GRIS data archive. It contains more than 500 data sets recorded in the years between 2014 and 2016. Most of them are single raster scans recorded in spectropolarimetric mode in the 1.08µm and 1.56µm wavelength bands. Some of them are measurements in spectroscopic mode, time sequences capturing the evolution of solar features, and observation in other wavelength bands such as 2.2µm.
