Evolution of a spicule observed in four different wavelengths ±774 mÅ and ±516 mÅ in the 10 June 2014 dataset. The columns are divided into 7 panels starting at the time 07:57:12.739 UT with steps of 3.9 s until 07:57:36.483 UT. The yellow arrow shows the location of the spicule first observed in that wavelength. The image intensities are normalised. The lower panel shows a normalized light curve of the feature indicated by the yellow arrow in the top panel. These light curves are plotted by summing intensity variations along ten positions along the length of the spicule.
