The complex distribution and mixing of magnetic polarities as observed by MDI (here displayed as yellow and blue) form a "magnetic carpet" over the entire Sun (upper right panel). The upper left panel shows the EUV emission taken simultaneously by CDS from plasma at the temperature of 250 000 K. The lower panel shows an overlay of the two images. Sequences of such images show that many of the transition region brightenings correspond to changes in the magnetic field.

Simultaenous observations of the distribution and mixing of magnetic polarities as observed by MDI (displayed as yellow and blue in the left panel) and the EUV emission observed by CDS from plasma at the temperature of 250 000 K. Towards the end he animations overlays the two movies. The field of view is 5 x 4 arcminutes and the actual duration is 1.5 hours. The observations were obtained at disk center on 15 August 1996
