Archives November 2006

Night of 28/29 November - For the first time in almost a month, the view of the mountain was clear for the entire night. There were two hotspots visible from sunset to sunrise. Due to ongoing computer glitches, only the processed images without the background of the mountain are available today - apologies to all. UPDATE: Stacked version with the raw data superimposed over a daytime image of the crater added below.
The animation below shows the processed images of the mountain which have been enhanced to maximise the brightness of the glow. The animation speed is set at 6 fps (equivalent of half an hour in real time per second).

Night of 19/20 November - The view of the crater was clear until around midnight, and there was some visible activity at the top of the lavadome for several hours last night.

Night of 18/19 November - There was a larger tremor, M3.4 at 20:20 last night, which was centred on the crater. There was a bright outburst at roughly the same time on the Volcanocam images, but the initial outburst occurred at 20:12 (according to the timestamp on the image). The outburst was located on the bottom right-hand side of the lavadome, a location that we haven't seen such activity previously. A stacked jpg image shows the location clearly, as does the animation below. BTW, these are first images of night-time activity for the month of November!
