This short animation based on Himawari-8 12 µm brightness temperatures provides information on the timing of the eruption and its duration. ~8 discrete pulses can ben seen followed by continuous emission and then it ends.
Himawari-8 3.9 µm brigtness temperatures showing a hot-spot followed by a cold cloud emitted by Raikoke. These data give constraints on the eruption time.
According to OMPS Limb Profiler (LP), the plume reached 14km. Attached two plots, OMPS aerosol extinction profiles (x 10000) around Raikoke. Dash line is the tropopause altitude. The figure shows the plume spreading between 11.5 to 14km. The second plot is the location of all profiles used in the first figure. The color scale is for stratospheric total column.

Analysis and forecast between 11-20 October 2019 of the Raikoke volcanic plume between 10-15km based on trajectory mapping of CALIPSO observations
from October, 11th to October 16th.
