Night of 30/31 January -  The moon illuminated the crater and the glow from the lavadome was visible for the entire night. The brightness of the hotspots was very consistent and the levels of seismicity were low.

Night of 29/30 January - The weather was clear and the hotspots near the top of the lavadome were quite active throughout the night. A few small rockfalls were also evident on the RHS of the lavadome.

Night of 28/29 January - The US Forest website was down for about 24 hours, but when it came back on-line most of last night's images were available (from 20:43 until sunrise). The images reveal the two hotspots near the top of the lavadome in a very uniform and consistent level of activity throughout the night.

Night of 27/28 January - The two visible hotspots near the top of the lavadome were visible for the entire night and there was one brief outburst lower down on the right hand side of the lavadome around 03:20 - possibly due to a rock fall. Otherwise, activity remains remarkably consistent!

Night of 26/27 January - The weather is remaining clear, providing good views of the mountain during the day and at night. The activity near the top of the lavadome is now clearly two separate (but closely spaced) hotspots, which were active throughout the night. A third hotspot made occasional appearances lower down and to the right of the growing lavadome. Seismic activity remains low, with several apparent rock falls visible on the South West Flank webicorder trace (see SWFL trace).

Night of 25/26 January - Another clear night with a strong showing from the hotspots near the top of the lavadome, but no major outbursts of activity - although the level of activity seemed to dim after 02:00. This may have been due to cloud/mist in the crater or the valley obscuring the view, or an actual decrease in the extrusion of hot material within the crater. It's impossible to tell from the processed images. Seismic activity remains quite low.

Night of 24/25 January - It was a clear night with an uninterrupted view of the crater. The activity from the hotspot at the top of the lavadome was very consistent, probably indicating the continuous extrusion of hot  lava/rock. Seismic activity was typical of the last weeks, with a couple of small rock falls indicated (e.g see SWFL webicorder trace).

Night of 23/24 January - The view of the crater was clear and the hotspots on the lavadome were visible for the entire night. The glow from the top of the lavadome was fairly consistent in its brightness and there were no major outbursts - despite some apparent rockfalls (e.g. see SWFL webicorder trace).

Night of 22/23 January - The clouds parted just before 04:00 this morning and revealed a reasonably bright hotspot at the top of the lavadome. There were a few small quakes last night, and what appears to be a small episode of tremor that was visible for a number of munutes at approximately 21:00 PST (see the traces from SWFL, SEP & YEL).

Night of 20/21 January - The clouds parted just before 22:00 last night and the active areas of the lavadome were visible for much of the night.

Night of 18/19 January - The view of the crater was relatively clear from 21:00 until just before sunrise this morning. The large hotspot near the top of the lavadome was quite bright and showed some activity overnight.

Night of 17/18 January - The large hotspot near the top of the lavadome was active and quite bright, for the brief period it was visible last night (about 3 hours after sunset).

Night of 15/16 January - The hotspot at the top of the lavadome was visible from sunset until around 03:30, when the clouds rolled in. There were no major outbursts in activity and the glow was reasonably bright and steady for much of the time.

Night of 14/15 January - The hotspots on the top of the lavadome began the night quite bright and slowly dimmed through the night - there is definitely another small hotspot appearing on the top of the lavadome, just to the left of the brightest glow.

Night of 13/14 January - The glow from the hotspot at the top of the lavadome appeared in the images just after 17:30 and grew brighter as the night went on. It also appeared that the hotspot was growing slightly in extent through the night - note the width of the hotspot in the ours before sunrise.

Night of 12/13 January - Another clear night and the hotspot on the top of the lavadome was very active and bright from sunset to sunrise.

Night of 11/12 January - The weather was clear and the hotspot on the top of the lavadome was visible and quite bright for most of the evening.

Night of 10/11 January - The clouds dissipated sometime after 23:00 and the glow from the lavadome was visible for most of the night after midnight. There were no major outbursts of activity, but the hotspot at the top and the one on the bottom right of of the lavadome were visible once the clouds lifted.

Night of 08/09 January - For the first time in a week the clouds lifted and gave us a view of the crater this morning. Unfortunately, it wasn't until 04:00, but at least it's something!

Night of 31/01 January - Happy New Year to all! Clouds obscured the view of the inner crater from sunset until around 23:30, then again an hours or so before sunrise. In the intervening time the crater was clear and the hotspot on the top of the lavadome burned fairly brightly through the night.
