Buenos Aires VAAC was reporting ‘eruption details: not available’ (rather than ‘continuous emission’) for Chaitén last night. Aviation colour code is still red, but was downgraded to orange for a while. Evidently the eruption plume is now small, low, and variable in its behaviour.

The Goes-12 visible-spectrum satellite image for 20:39 UTC yesterday (from the Servicio Meteorológico Nacional of Argentina) shows a small plume being blown to the east. The original image should be available via this link.

A range of satellite images can be found at this Flickr page: Erupción del volcán Chaiten. I’m very grateful to Alan Sullivan at Fresh Bilge for this link.

Nothing new today on Chaitén from SERNAGEOMIN or ONEMI.

I’m putting together a post on the environmental impact (so far) of the Chaitén eruption; if anyone has any relevant sources they would like to bring to my attention, in English or Spanish, please get in touch. The post should appear, other commitments allowing, at the beginning of next week.
