Filament Erupts, Solar Activity Rising

Well, after not doing much at all, the Sun is finally showing some activity. A plasma filament lifted up snapped off. A Coronal Mass Ejection (CME) was recorded. When it does hit the Earth in the next couple of days, it should be minor. The Solar Wind is very low and stable and the Planetary K-index is showing this with very low green levels. We should expect an uptick tonight. If not, then we should get more of this...

Earthquakes

6.5 magnitude earthquake near, West Java, Indonesia
5.4 magnitude earthquake near Fiji
5.3 magnitude earthquake on the Central Mid-Atlantic Ridge
5.0 magnitude earthquake on the Pacific-Antarctic Ridge

And there were plenty more.
And on the volcano side

Space Objects

Yesterday I mentioned how there were multiple Near Earth Objects(NEOs) stacking up for the 15th of December, well the 21st is getting a bunch itself. I guess the empty database will fill up as the month comes to a close.

huh...never heard of cold lava...so I looked it up
also know as lahar

A lahar is a volcanic mudflow or debris flow.[2] Lahars have the consistency, viscosity and approximate density of wet concrete: fluid when moving, solid at rest.[3] Lahars can be huge. The Osceola lahar produced by Mount Rainier (Washington) some 5600 years ago resulted in a wall of mud 140 metres (460 ft) deep in the White River canyon, which covered an area of over 330 square kilometres (130 sq mi), for a total volume of 2.3 cubic kilometres (0.55 cu mi).[4]
.
A lahar of sufficient size and intensity can erase virtually any structure in its path, and is capable of carving its own pathway, making the prediction of its course difficult. Conversely, a lahar quickly loses force when it leaves the channel of its flow: even frail huts may remain standing, while at the same time being buried to the roof line in mud. A lahar's viscosity decreases with time, and can be further thinned by rain, but it nevertheless solidifies quickly when coming to a stop.
.
Lahars vary in size and speed. Small lahars less than a few metres wide and several centimetres deep may flow a few metres per second. Large lahars hundreds of metres wide and tens of metres deep can flow several tens of metres per second (22 mph or more): much too fast for people to outrun.[3] With the potential to flow at speeds up to 100 kilometres per hour (60 mph), and flow distances of more than 300 kilometres (190 mi), a lahar can cause catastrophic destruction in its path.[5]
