(a) A composite of AIA images: 94 Å (red), 171 Å (green), and 193 Å (blue) highlighting the active regions (most of the red background). A 32.25 MHz LOFAR source at 11:56:56 UT is overlaid. (b) A composite image of AIA at the same time as (a), but using a different color table. The triangle symbols indicate the centroids of the fundamental LOFAR source at the frequencies and times corresponding to the green asterisks in Figure 3(a).
