November 2005

Night of 27/28 November - The weather was relatively clear and the glow was visible throughout the night. There was a larger tremor at approximately 17:57 last night, which corresponded with a bright outburst from the lavadome. This was followed by another, brighter outburst in activity around 22:25. 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.  Neither of these animations has been processed to compensate for the focus problem with the Volcanocam.

Night of 26/27 November - The clouds parted briefly after sunset and before sunset this morning and provided a faint glimpse of the glow from the lavadome. The animation below consists of strongly enhanced images, which were not processed to compensate for the focus problem with the Volcanocam.

Night of 23/24 November - The weather was again clear and there was another bright outburst around 22:45 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, the second was further enhanced to emphasise the brightness of the glow.  Neither of these animations has been processed to compensate for the focus problem with the Volcanocam.

Night of 22/23 November - The view was clear last night and the glow was faintly visible from sunset until a very bright outburst this morning just after 5 o'clock. Below is an animation of the images, processed to remove the noise and slightly enhanced. It may be possible to run the deconvolution routines on the sequence of bright images, but I won't be able to try until I get home from work tonight... In the meantime, here's the un-deconvoluted show...

Night of 21/22 November - The view of the crater was clear again last night and the glow from the lavadome was visible. I also spent several hours last night attempting to compensate for the current focus problems with the Volcanocam using an image processing technique called deconvolution. Unfortunately, it was particularly successful. It is obvious (now) that unless the glow is very bright, there simply isn't enough information in the Volcanocam images to extract a reconstructed image from the data. The main problem being that because of the way the focus has shifted, the near infra-red focus is blurred to a very large degree - and deconvolving the images only leads to a limited reconstruction, more reminiscent of a contour diagram than the original image. Below is a view of heavily processed images from last night which shows the current noisy and blurred images - not processed using deconvolution. Which is probably the best that I can manage unless the glow is very bright which provides more opportunity to compensate for the focus problem...

Night 19/20 - 20/21 November - The good weather continues... The glow was visible for a large part of last night and it was also bright and active for a brief period yesterday morning - which provided a good source of images to develop the parameters for de-blurring the images from the Volcanocam. Below is a brief sequence from the early morning on Sunday, showing the images of the glow processed by deconvolution to attempt to compensate for the focus of the Volcanocam camera. The images from last night and this morning will take some time to process, but I hope to process them tonight and post the results.

Night of 14/15 November - The view of mountain was clear for most of last night and the full moon illuminated the view. Unfortunately, the focus problems with the Volcanocam mean that the image is more diffuse and a bit blurrier than usual. There were a couple of bright outbursts from the lavadome (if you watch carefully). The animation below was processed to remove noise and slightly enhanced to maximise the brightness of the glow, but I wasn't able to do anything about enhancing the details in the image to compensate for the focus issues. If you watch the animation from a greater distance from the screen you may be able to get a better sense of what's happening. I haven't included a stacked version as it is difficult to separate out the glow from the background.

13/14 Nov - More clouds, more bad weather and nothing on the Volcanocam images last night, despite a larger tremor at 23:26 last night :-(

12/13 Nov - There's no icicles visible on the Volcanocam images this morning, neither were there any views of the crater last night. The weather forecast for Mount St Helens offers a little hope for clearer overnight weather as the week progresses. Stay tuned...

11/12 Nov - Clouds once again obscured the view of the crater. Although for a brief time this morning there were glimpses of the mountain from the Volcanocam, showing the view of the crater nicely framed by icicles!

10/11 Nov - Clouds obscured the view of the crater last night. The USFS are also reporting that they have scheduled further maintenance to correct the slight focus problem with the Volcanocam. Which should mean clearer night time images once again...

Night of 09/10 November - The Volcanocam was repaired yesterday morning - big thanks to the maintenance crew at JRO! Unfortunately, it appears that the focus of the camera may have been altered slightly during the repairs. The glow was visible from sunset to sunrise, but the images of the glow appear to be larger and more diffuse than prior to the repairs. 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).

08/09 Nov - The blue screen still lingers on the Volcanocam website. The USFS are reporting that a power failure to the camera is the likely cause and that they may be able to assess - and hopefully repair - the problem today...UPDATE (12:05): The Volcanocam is back on line - yippeeeee!!!!

07/08 Nov - The Volcanocam is still producing blue screens and the US Forest Service are reporting that the road to the Johnson Ridge Observatory will be ploughed today to give them access. It is also reassuring that the problem is not related to any underhanded Smurf activity... Here's hoping that it is not a serious problem with the camera. The webicorder traces from the crater do not show any major change in seismic activity overnight.

06/07 Nov - The Volcanocam still appears to suffering a communications problem - there were no images transmitted to the public servers last night :-(

05/06 Nov - Clouds obscured the view of the crater from the Volcanocam until 18:43 last night. All the images transmitted to the public server since then only show a featureless blue screen. Hopefully this is only a temporary glitch and we will have live pictures again soon... Levels of seismic activity during the night were fairly consistent with what we have been observing over the last weeks, with a constant stream of small drumbeat tremors occurring every minute or so. The webicorder traces also show a larger tremor this morning at around  09:24.

04/05 Nov - Once again, clouds completely obscured the view of the crater last night :-(

03/04 Nov - More clouds, more bad weather, no view of the mountain last night from the Volcanocam :-(

02/03 Nov - Clouds completely obscured the view of the crater last night :-(

Night of 01/02 November - Clouds obscured the view of the crater for almost the entire night. There was one short lived and bright outburst just after 23:30 last night, but it was only visible in a couple of images from the Volcanocam - not enough for an animation. Here are views of the outburst showing just the glow and stacked on a background image of the mountain (jpgs only).

Night of 31/01 November - The glow was only visible between 19:00 and 21:30 last night - before that the clouds obscured the view of the crater. 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).
