February 2005

Night of 27/28 Feb - the glow was only visible a few sporadic times between sunset and midnight last night, presumably when the clouds rolled in and obscured the view. The movie below was processed to remove the noise and enhance the brightness of the glow.

Night of 26/27 Feb - the glow was very faint, though visible, throughout the night. The movie below was processed to remove the noise and enhance the brightness of the glow.

Night of 25/26 Feb - the glow was visible throughout the night. Below are two movies - the first was processed to remove the noise and shows the brightness of the event as seen on the Volcanocam images. The second was processed to isolate and enhance the brightness of the glow.

Night of 24/25 Feb - the glow was quite active for all of the night, with minor flaring occurring several times. Below are two movies - the first was processed to remove the noise and shows the brightness of the event as seen on the Volcanocam images. The second was processed to isolate and enhance the brightness of the glow.

Night of 23/24 Feb - the were two small outbursts of activity last night at 21:53 and 03:43 local time. These events were considerably smaller than those seen over the previous couple of nights. Below are two movies - the first was processed to remove the noise and shows the brightness of the event as seen on the Volcanocam images. The second was processed to isolate and enhance the brightness of the glow.

Night of 22/23 Feb - there were multiple outbursts of activity this morning. The first occurred at 02:13, then at 04:08 a large flash was followed by dual glows on opposite sides of the lavadome. This may imply a significant landslide which exposed hot lava on both flanks of the lavadome. Below are two movies - the first was processed to remove the noise and shows the brightness of the event as seen on the Volcanocam images. The second was processed to isolate and enhance the brightness of the glow.

Night of 21/22 Feb - there was a major outburst of activity at 03:03 this morning. Below are two movies - the first was processed to remove the noise and shows the brightness of the event as seen on the Volcanocam images. The second was processed to isolate and enhance the brightness of the glow.

Night of 20/21 Feb - the moon illuminated the mountain and the glow was visible throughout the night. Below are two movies, the first was processed to remove the noise and slightly enhanced, the second was processed to isolate and maximise the brightness of the glow.

Night of 19/20 Feb - the glow was dimly visible for half of the night then clouds obscured the mountain for most of the rest of the evening. Below are two movies, the first was processed to remove the noise and shows the glow as seen on the Volcanocam images, the second was processed to maximise the brightness of the glow.

Night of 18/19 Feb - there were numerous small bright flashes last night, clearly indicating that small landslides were occurring on both sides of the lavadome. Most likely as a result of the cracks that have developed along the ridge of the growing dome and reported yesterday by the USGS/CVO.

Night of 17/18 Feb - there was a good view of the mountain and there were no major outbursts of activity during the night. However, the glow was exceedingly faint and only visible by carefully adjusting the brightness of the images. Note that the glow is so faint that processing is isolating only 5 or 6 levels of brightness above the background noise, rather than the usual hundreds, hence the blocky (digital) appearance of the images.

Night of 16/17 Feb - there was a good view of the mountain and there were no major outbursts of activity during the night.

Night of 14/15 Feb - there was a good view of the mountain and the glow was visible for most of the night. However, there were no major outbursts of activity overnight.

Night of 11/12 Feb - there were two small outbursts of activity at 20:08 and 21:38 last night and on different parts of the lavadome. Below are two movies, the first was processed to remove the noise and shows the glow as seen on the Volcanocam images, the second was processed to maximise the brightness of the glow.

Night of 09/10 Feb - there was an outburst of activity at 01:38 this morning. Below are two movies, the first was processed to remove the noise and shows the glow as seen on the Volcanocam images, the second was processed to enhance the brightness of the glow.

Night of 08/09 Feb - the glow was faintly visible throughout the night and there was a small (& brief) outburst of activity at 03:48 this morning. In the movie below, the brightness of the glow has been greatly enhanced to improve visibility.

Night of 07/08 Feb - the glow was visible throughout the night, but once again very faintly. In the movie below, the brightness of the glow has been greatly enhanced to improve visibility.

Night of 06/07 Feb - the weather cleared sometime after sunset and another bright flash occurred at 01:13 this morning. The glow was then visible for the following several hours. Below are two movies, the first showing the brightness of the glow after removing the noise (i.e. as 'seen' by the Volcanocam) and the second after enhancing the brightness of the glow to maximum levels.

Night of 03/04 Feb - the glow was visible dimly throughout the night before a bright flash occurred at 3:38. Following this the glow quite rapidly disappeared - most likely due to clouds obscuring the mountain.

Night of 02/03 Feb - the glow was a little more active last night (possibly because of the small ash/steam eruption that occurred yesterday afternoon) and lasted throughout the night. Below are two movies, the first showing the brightness of the glow after removing the noise (it's very faint!) and the second after enhancing the brightness of the glow to maximum levels.

Night of 01/02 Feb - another fairly feeble display last night. There's a lot of processing "noise" in the image, as the brightness of the glow isn't much greater than the background levels - but it is still there...
