Night of 16/17 February - The clouds lifted around 00:30 this
morning and the hotspots on the lavadome were active and visible until sunrise.
Levels of seismic activity in the crater were similar to that over the previous
days, with a number of small tremors recorded overnight (e.g. see the
SEP (Old Dome) webicorder trace).
The animation below shows the processed images of the mountain which have been
enhanced to maximise the brightness of the glow and 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) - only the images
between midnight and sunrise are included.

Night of 15/16 February - The clouds lifted around 02:00 this
morning and the hotspots on the lavadome were active and visible until sunrise.

Night of 13/14 February - Despite the clouds before sunset and
after sunrise this morning, the hotspots on the lavadome were visible on the
Volcanocam images for most of last night, with only a few interruptions. The bright display may be linked to
the
M3.4 quake that rattled the lavadome at 16:15 yesterday afternoon, when the
view of the crater was obscured by the clouds. BTW, happy Valentines Day to all!

Night of 12/13 February - The hotspots on the lavadome were active
from sunset until midnight, when the clouds once again obscured the view.

Night of 09/10 February - The clouds lifted just after midnight to
reveal a bright display from the twin hotspots near the top of the lavadome.

Night of 06/07 February - The clouds parted around 01:00 this
morning and the hotspots on the lavadome were intermittently visible until
sunrise.

Night of 05/06 February - Another clear night with good views of
the crater from sunset until sunrise. The two hotspots crowning the lavadome
burned brightly and relatively consistently through the night. There were no
notable outbursts or any large tremors.

Night of 04/05 February - We had a good view of the crater and the
activity on the lavadome last night. There were a couple of active hotspots, but
no major outbursts of activity - indicative of the relatively consistent
extrusion of magma and hot material.

Night of 03/04 February - Clouds obscured the view of the crater for most of last night, with only a few brief glimpses of the hotspots on the lavadome visible between 05:00 and sunrise. Not really enough images for an animation, so I stacked the images where the glow was visible to show the level of activity (see stacked image). It seems the activity continues pretty much as we have seen in recent days and weeks.
Night of 02/03 February - Another clear night with good views of
the activity in the crater. There were a number of small tremors, but otherwise
the level of seismic activity remains very low.

Night of 01/02 February - The full moon illuminated the crater and
the glow from the lavadome was visible throughout the night. There was a
M3.4 tremor at 15:45 yesterday afternoon - the largest we have seen for many
weeks - otherwise the levels of seismic activity remained low.

Night of 31/01 February - The hotspots near the top of the lavadome
were active all night. The levels of seismic activity remain very low and there
were no major outbursts during the night.
