A Xmas mystery on Mount St Helens
Mount St Helens has been quietly active over the last few days, with two hot-spots visible in the crater last night - as shown in the stacked set of images above - and intermittently over the last week or so.
However, at 18:47 yesterday evening a large bright light appeared above and to the left of the crater as seen in this enhanced image which was superimposed over a daylight image of Mount St Helens for reference.
This bright spot only appeared on this one image, and no others. So it is likely that it is nothing more than a glitch or due to noise - however, the spot is much larger than the usual noise spikes that I have seen in the images from the Volcanocam over the last two years.
Below is the original image, and beneath that a b&w image with that had the noise filtered out - so you can see that I'm not making this up!
Any thoughts as to what it may be?
