A pair of glows in the night
On Wednesday, Thursday and Friday nights the two glows were fairly bright and easily seen in the enhanced images of the crater. There's still really no explanation for the bright spot on the western flank of the mountain, and so far the USGS hasn't posted any new images of the area.
One thought does occur to me though. Looking at the clear daytime images from late April (before the anomalous glow appeared) the area where its located seemed to have less snow cover than it has on present daytime images. I wonder if a slab of snow/ice has formed that it sitting at just the right angle to reflect light to the Volcanocam? Of course, the real question then becomes, what is the source of bright infra-red light?
16 images from the Volcanocam from last night, combined to show the glow from the lavadome and the anomalous little glow on the western flank of Mount St Helens.
