December 2004

Night of 27/28 December - the glow was visible from sunset to sunrise and the moon illuminated the mountain for most of the night. Unfortunately, I have not been able to process the entire frames to improve the focus, while maintaining enough detail in the images to make it worthwhile. So once again, only the area of the crater was processed to reduce noise, de-blurred and animated in this movie.

Night of 23/24 December - the glow was visible from sunset to sunrise. NB. Only the area of the crater was processed to reduce noise, de-blurred to improve the view and animated in this movie.

Night of 22/23 December - the glow was visible from just after 7:00pm until sunrise. The moon partially illuminated the mountain during the night, but due to the focus issues with the Volcanocam, it was not possible to compensate for the focus of the glow and the mountain. So only the area of the crater was processed to reduce noise, de-blurred to improve the view and animated.

Night of 20/21 December - the glow was visible from 7:00pm until just before 2:30 am - presumably when the clouds rolled in again. The movies are processed to reduce noise and de-blurred to improve the view. NB. Only the area around the glow has been animated in the movie.

Night of 18/19 December - the glow was visible from sunset until the clouds rolled in around 05:00am this morning. The movies are processed to reduce noise and de-blurred to improve the view. NB. Only the area around the glow has been animated in the movie.

Night of 17/18 December - the glow was visible from sunset to midnight, then from about 04:00am until sunrise. The two movies are processed to reduce noise and de-blurred to improve the view. NB. Only the area around the glow has been animated in the movie.

Night of 16/17 December - the glow was visible all night and showed a little more activity than the previous couple of nights. The two movies are processed to reduce noise and de-blurred to improve the view. NB. Only the area around the glow has been animated in the movie.

Night of 15/16 December - the glow was visible for the entire night! The movie below has been processed for noise and I have used a slightly less aggressive deconvolution process than previously to sharpen the individual frames. NB. Only the area around the glow has been animated in the movie.

Night of 14/15 December - the glow appeared just after 4:00am, but diffuse and ill-defined due to the focus issues with the Volcanocam. The Flash movie below has been processed to sharpen the images of the glow, as well as the usual noise reduction processing.

Night of 11/12 December - the glow was visible all night, but once again larger and more diffuse than seen previously. It is now apparent that the recent adjustments to the focus of the Volcanocam have adversely effected the quality of the images.
Below are two movies of the glow from last night - one is simply the images from the Volcanocam overlaid over a reference image of the mountain. The other I have processed using a deconvolution algorithm to attempt to compensate for the lack of focus of the glow. I cannot in any way guarantee that the sharpened version reflects what's really happening. Note: Only the crater area is animated in these movies.

Night of 02/03 December - the glow was visible all night, but larger and more diffuse than seen previously. This may be due to either steam obscuring the incandescent lava or be the result of the adjustment of the focus on the Volcanocam when it was cleaned yesterday. Note: Only the crater area is animated in these movies.

Night of 01/02 December - a fantastic display with multiple glows flickering on and off all night :-) Note: Only the crater area is animated in these movies.
