Eruption Event Movie - October 26-27, 2004 - Dancing In The Moonlight (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 26-27, 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. Weather conditions were
not ideal so expect the image to be lost in camera noise as clouds moved
through the area.
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.
