According to Volcanodiscovery , following a rapid increase in tremors starting at 07:24 (local time) in the morning, the south-east crater began to emit lava fountains and ash/SO2 plumes until around 9 am.
Meteosat-8 captured the ash/SO2 cloud and its movement/expansion towards the north-east. In the beginning, the ash signal dominated the RGB composite (see Ash RGB at 05:45 UTC ), but later, as the volcanic cloud moved towards Greece, the SO2 signal became more and more visible (the sulfur dioxide cloud is shown in green colour, see Ash RGB at 11:45 UTC ). Luckily, at 11:47 UTC the AIRS instrument on the Aqua platform also captured the SO2 plume over Western Greece (see AIRS retrieval , source: F. Prata). A comparison with MSG shows a very good agreement of the position and the size of the SO2 cloud (see comparison ).
