Night of 30/01 May - There was a bright outburst last night at 22:34 which corresponded with a larger tremor as seen on the SHW webicorder trace from last night. Unfortunately, clouds obscured the crater for the rest of the night following the event. The first animation below shows the processed images at the approximate brightness as seen in the Volcanocam images and the second shows enhanced images superimposed over a daytime image of the crater for reference. The animation speed is set at 6 fps (equivalent of half an hour in real time per second) and only the images where the glow was visible are included.

Night of 28/29 April - Despite apparently clear weather, the glow from the lavadome was only visible in one frame at 03:45 this morning. Here's the processed b&w image [jpg, 94kB] and the enhanced & stacked [jpg, 85 kB] version.

Night of 27/28 April - There were three outbursts last night at 23:48, 01:33 and 04:33, with the one just after one-thirty the largest. The first animation below shows the processed images at the approximate brightness as seen in the Volcanocam images and the second shows enhanced images superimposed over a daytime image of the crater for reference. The animation speed is set at 6 fps (equivalent of half an hour in real time per second) and only the images where the glow was visible are included.

Night of 24/25 April - There was a large and quite spectacular outburst last night at 23:32, which corresponded to a larger tremor clearly seen on the webicorder traces (e.g. see SHW). The animation below shows the processed images at the approximate brightness as seen in the Volcanocam images at an animation speed is set at 6 fps (equivalent of half an hour in real time per second).

Night of 23/24 April - I'm back from holidays and so is the glow - it made a couple of brief appearances last night. I hope to be able to go over the images from last week and post any interesting events over the next couple of days. The animation below shows the processed images at the approximate brightness as seen in the Volcanocam images at an animation speed is set at 6 fps (equivalent of half an hour in real time per second).

Night of 12/13 April - The almost full moon illuminated the crater throughout the night. However, the glow from the extruding lavadome was only visible at two times during the night, at 23:48 and 02:13. The animation below shows the processed images at the approximate brightness as seen in the Volcanocam images at an animation speed is set at 6 fps (equivalent of half an hour in real time per second).

Night of 10/11 April - The moon is near to full and it illuminated the crater for most of the night. A strong steam plume was visible, but there was no sign of the glow from the lavadome! It is not obvious whether this was because the steam plume obscured the glow, or whether the extrusion of the lavadome is proceeding out of sight from the Volcanocam at JRO. The animation below shows the processed images at the approximate brightness as seen in the Volcanocam images at an animation speed is set at 6 fps (equivalent of half an hour in real time per second).

Night of 06/07 April - The glow from the lavadome was visible from 23:47 (when there was a small landslide/rock fall) until just after 02:00 - it wasn't visible at any other time during the night. The first animation below shows the processed images at the approximate brightness as seen in the Volcanocam images and the second shows enhanced images superimposed over a daytime image of the crater for reference. The animation speed is set at 6 fps (equivalent of half an hour in real time per second) and only the images where the glow was visible are included.
