Time variability of Io's volcanic activity from near-IR adaptive optics observations on 100 nights in 2013-2015

Two eruptions seen at Kurdalagon Patera in January and April 2015 occurred simultaneously with a brightening of the neutral cloud and plasma torus which are sourced from Io's atmosphere. A plume at Kurdalagon Patera, such as was seen by New Horizons in 2007, could have been responsible for the influx of material that caused these brightenings.
