This event started with ash emissions at approximately 21:00 LT (14:00 UTC) which reached heights of about 16 km during the strongest period at approximately 23:30 LT. The first notification was shown via the SACS system (see ), showing an AIRS overpass at 18:11 UTC  with max 34.6 DU SO2 . AIRS is detecting  a 'ring' of SO2 around the opaque central umbrella cloud of the plume.




CALIPSO overpassed the center of the Kelut cloud at 18:10 UTC. The ash plume penetrated the tropopause, reaching as high as 26 km into the stratosphere.
