Observations of Augustine Volcano (Feb-Mar 2006)
Using a Small Astronomical Camera

Pilots reported lightning in the plume of Augustine Volcano when it erupted in late 2005/early 2006. In an attempt to capture images of the lightning, nighttime observations of Augustine were made from Jan – Apr 2006 with a small astronomical camera popular with the amateur astronomy community. The observations were made from the AVO/USGS field site in Homer, Alaska, which gives an unobstructed view of Augustine 105 km away looking WSW across the open waters of the Cook Inlet. No large eruptions producing lightning occurred during the observations, but it was unexpectedly discovered that the camera could detect thermal emissions of pyroclastic flows, rock falls and steam releases during the nighttime that were otherwise undetectable either visually or with standard optical photographic cameras. This talk will present some of the observations and the analysis methods used to interpret the imaging data in terms of the thermal characteristics of the Augustine emissions.
