26 Kompozycja barwna RGB uzyskana na podstawie pomiarów przyrządem SEVIRI na satelicie MSG2 o godzinie 06 UTC (a), 12 UTC (b), 16 UTC (c) dnia 16 kwietnia oraz o 12 UTC 17 kwietnia. Odcienie żółte odpowiadają pyłowi wulkanicznemu znajdującemu się ponad obszarem pokrytym chmurami. Barwy niebieskie oznaczają chmury zbudowane z kryształów lody, czerwone chmury zbudowane z kropelek wody, kolorem czarnym i brązowym oznaczone są obszary pozbawione zachmurzenia.
