Eruption Event Movie - October 27-28, 2004 - Blinded By The Light (Night Glow Images)
The VolcanoCam has an apparent limited IR capability.
We discovered this when it was found the VolcanoCam was able to record
magma extruding into the crater of Mount St. Helens, begining around
October 10 and 11, 2004.
The full moon of October 27-28, 2004, offers a unique opportunity to
view Mount St. Helens at night, complete with magma visibly extruding
into the crater as captured by the VolcanoCam. In addition, this night
was also a full lunar eclipse. However, by the time the effects of the
eclipse ended around 10:00 pm, the full moon and clear night sky afforded
an extraordinary view of Mount St. Helens as viewed by the VolcanoCam.
Compare this movie to the movie from the previous evening.
None of the images in this movie are enhanced to reduce noise. This
movie is best observed from a distance of at least five to six feet away
from the computer monitor with the room lights dimmed.
