Cloud cover prevented web camera views on 16 November, but satellite imagery showed an ash plume drifting 100 km SW and sparse ashfall to the E. During 18-20 November plumes observed with the web camera rose 2.5-3 km above the crater. Satellite imagery showed ash clouds drifting E and SE on 18 November and an ash plume drifting 250 km SE on 19 November. During the night on 20 November the crater was incandescent. Cloud cover prevented observations on 21 November. The Alert Level remained at Red.According to a news article, flights in Uruguay and Argentina were disrupted or cancelled on 22 November due to the presence of ash.
