| ABSTRACT
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.
