October 2005

Night of 29/30 October - Despite the crater being obscured by clouds at sunset and at sunrise, the clouds parted during the night affording a view of the crater. The glow was visible for about an hour after 23:00, and then a couple of times later in the night. Below are two animations combining the images from last night - the first shows slightly enhanced images of the glow, the second were further enhanced to emphasise the brightness of the glow. Note the images of the glow in the second animation are slightly shifted in relation to the first, to maintain alignment with the background image (due to the fact the Volcanocam camera was moved during cleaning back on the 13th September).

Night of 26/27October - The crater was clear of clouds and there was a strong steam plume rising into the sky as the sun set. The glow was quite active throughout the entire night. Below are two animations combining the images from last night - the first shows the glow at the approximate brightness as recorded on the Volcanocam images, the second was further enhanced to emphasise the brightness of the glow. Note the images of the glow in the second animation are slightly shifted in relation to the first, to maintain alignment with the background image (due to the fact the Volcanocam camera was moved during cleaning back on the 13th September).

Night of 24/25 October - The glow was visible from sunset until sunrise and quite active throughout the night. As seen in the animations, the glow is not confined to a single location on the lavadome, but appears to be originating from a number of different sites (also see this combined image from last night). Below are two animations combining the images from last night  - both were processed to remove noise and enhanced to maximise the brightness of the glow, with the second superimposed on a background image of the mountain. Note the images of the glow in the second animation are slightly shifted in relation to the first, to maintain alignment with the background image (due to the fact the Volcanocam camera was moved during cleaning back on the 13th September).

Night of 22/23 October - The night started off very quietly, then there was a small outburst at 21:35, followed by a brighter and more sustained display beginning at 03:00 this morning. Below are two animations combining the images from last night  - both were processed to remove noise and enhanced to maximise the brightness of the glow, with the second superimposed on a background image of the mountain.

Night of 21/22 October - It was a clear night and the glow was fairly active throughout the night. A composite image of the enhanced images from last night shows that there are at least four sites which are contributing to the glow. Below are two animations combining the images from last night - the first shows slightly enhanced images of the glow, the second were further enhanced to emphasise the brightness of the glow.

Night of 20/21 October - The sky was clear and there was a glorious view of the crater last night. The incandescent glow from the lavadome was relatively bright and there was a fairly vigorous steam plume visible as well. Below are two animations combining the images from last night  - both were processed to remove noise and enhanced to maximise the brightness of the glow, with the second superimposed on a background image of the mountain. Note the images of the glow in the second animation are slightly shifted in relation to the first, to maintain alignment with the background image (due to the fact the Volcanocam camera was moved during cleaning back on the 13th September).

Night of 18/19 October - The incandescent glow from the lavadome was visible from sunset until clouds obscured the view of the crater around 03:00 this morning. Below are two animations combining the images from last night - the first shows the glow at the approximate brightness as recorded on the Volcanocam images, the second was further enhanced to emphasise the brightness of the glow. Note the images of the glow in the second animation are slightly shifted in relation to the first, to maintain alignment with the background image (due to the fact the Volcanocam camera was moved during cleaning back on the 13th September).

Night of 17/18 October -  The moon was full and illuminated the mountain and the passing clouds. The glow wasn't particularly active, but was visible for most of the night. Below are two animations combining the images from last night - the first shows slightly enhanced images of the glow, the second was further enhanced to emphasise the brightness of the glow. Note the images of the glow in the second animation are slightly shifted in relation to the first, to maintain alignment with the background image (due to the fact the Volcanocam camera was moved during cleaning back on the 13th September).

Night of 12/13 October -  The glow was visible in a few small outbursts before midnight when when clouds obscured the view. Interestingly, the glow appears on both sides of the lavadome, possibly indicating rock falls on either side of the lavadome. Below are two animations combining the images from last night - the first shows slightly enhanced images of the glow, the second was further enhanced to emphasise the brightness of the glow. Note the images of the glow in the second animation are slightly shifted in relation to the first, to maintain alignment with the background image (due to the fact the Volcanocam camera was moved during cleaning back on the 13th September).

Night of 11/12 October - The first anniversary of the appearance of the glow! Unfortunately, the mountain didn't put on a particularly spectacular show last night in celebration. Clouds obscured the view earlier in the evening, but there was one bright outburst at 01:15. Otherwise nothing much of note. Below are two animations combining the images from last night - the first shows slightly enhanced images of the glow, the second was further enhanced to emphasise the brightness of the glow. Note the images of the glow in the second animation are slightly shifted in relation to the first, to maintain alignment with the background image (due to the fact the Volcanocam camera was moved during cleaning back on the 13th September).

Night of 09/10 October - There was a considerable number of small tremors recorded at Mount St Helens last night (e.g. SHW webicorder trace, listing). The glow from the lavadome was quite active throughout the night, but there were no particularly large outbursts of note. Below are two animations combining the images from last night - the first shows slightly enhanced images of the glow, the second was further enhanced to emphasise the brightness of the glow. Note the images of the glow in the second animation are slightly shifted in relation to the first, to maintain alignment with the background image (due to the fact the Volcanocam camera was moved during cleaning back on the 13th September).

Night of 07/08 October - There were a number of small tremors last night, but this didn't result in any major outbursts in activity. The glow from the lavadome was faintly visible in the de-noised images, but required substantial enhancement to make it clearly visible. Below are two animations combining the images from last night - the first shows the glow at the approximate brightness as recorded on the Volcanocam images, the second was further enhanced to emphasise the brightness of the glow. Note the images of the glow in the second animation are slightly shifted in relation to the first, to maintain alignment with the background image (due to the fact the Volcanocam camera was moved during cleaning back on the 13th September).

Night of 04/05 October - The glow from the lavadome was quite faint last night and there were no major outbursts of activity. However, in the highly enhanced images the glow appears quite active just after sunset and then earlier this morning. Below are two animations combining the images from last night - the first shows the glow at the approximate brightness as recorded on the Volcanocam images, the second was further enhanced to emphasise the brightness of the glow. Note the images of the glow in the second animation are slightly shifted in relation to the first, to maintain alignment with the background image (due to the fact the Volcanocam camera was moved during cleaning back on the 13th September).

Night of 02/03 October - Despite the apparent thick cloud cover during the night, the glow made a couple of appearances in the heavily enhanced images. It was almost imperceptible on the de-noised images alone without image enhancement. Below are two animations combining the images from last night  - both were processed to remove noise and strongly enhanced to maximise the brightness of the glow, with the second superimposed on a background image of the mountain. Note the images of the glow in the second animation are slightly shifted in relation to the first, to maintain alignment with the background image (due to the fact the Volcanocam camera was moved during cleaning back on the 13th September).
