September 2005
Night of 28/29 September - There
were a couple of bright outbursts from the lavadome before the clouds moved in
to obscure the view of the crater around 01:00 this morning. Below are two
animations combining the images from last night (before the clouds obscured the
view) - both were processed to remove noise and slightly enhance 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).

were several rock falls and associated bright outbursts from the lavadome last
night. Below are two animations combining images from last night - both were

Night of 25/26 September - The
weather was clear and the night began with a bright outburst at 19:51, followed
by several more at 23:21, 00:41, 01:41 and other smaller events. 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.

Night of 24/25 September - The
night began with a small glow emanating from the lavadome and there was a small
outburst at 22:56, followed by two much larger outbursts in activity at 00:21
and 04:51 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 with the
noise removed, the second shows the same images superimposed on a background
image of the mountain.

Night of 23/24 September - There
was an obvious rock slide resulting in a bright outburst in the images around
midnight last 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 with the
noise removed, the second shows the same images superimposed on a background

Night of 22/23 September - The
night began with a bright outburst at 20:11 and the glow continued to flicker
away for the rest of the 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 with the
noise removed. In the second the images were further enhanced to maximise the
brightness of the glow and then superimposed on a background
image of the mountain.

visible for the entire night. Below

Night of 20/21 September - There
was a bright outburst from the lavadome this morning at 04:56, which
corresponded to a small quake that is clearly visible on the
SHW
webicorder trace for last night. Unfortunately, the Volcanocam appears to
have suffered another network problem last night. It stopped transmitting images
to the server at 19:46 and only started re-transmitting images at 03:36 this
morning. Below
are two animations combining the limited number of images from last night - both were processed to
remove noise and slightly enhance the brightness of the glow, with the second superimposed on a background
image of the mountain.

Night of 18/19 September - Despite
some clouds persisting all night, the glow was visible throughout. There were a
few minor outbursts indicative of small rock falls from the lavadome. Below
are two animations combining the images from last night - both were processed to
remove noise and slightly enhance the brightness of the glow, with the second superimposed on a background
image of the mountain.

17/18 September - Clouds obscured the
view until just after 01:00 this morning and then parted to allow a view of the
crater and the glow from the lavadome. There were two small outbursts of
activity at 01:56 and 02:31. Below is an animation of the images from when the
crater was in view of the Volcanocam, the images were processed to remove noise
and slightly enhanced to improve contrast.

Night of 13/14 September - There
were no major outbursts last night, but the glow was faintly visible for the
entire night. Below are two animations combining the images
from last night - the first shows slightly enhanced images of the glow, the second was
greatly enhanced to
maximise the brightness of the glow.

14 Sep - Yesterday the camera lens on the Volcanocam was cleaned and the camera was moved slightly. This helped prove that the anomalous glow that sometimes appears on the images of the western flank of the crater is the result of defective pixels in the Volcanocam - see the images from the 11/12 and 12/13th that confirm it here, or read the story of the anomalous glow here.
Night of 12/13 September - There
was a large outburst from the lavadome at 02:51 this morning. Also note that the
Volcanocam lens was cleaned yesterday and the camera view was altered slightly -
so I have shifted the position of the glow in the stacked animation to
compensate. 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 with the
noise removed, the second shows the same images superimposed on a background
image of the mountain.
