Three tremors - three bright outbursts from the lavadome
According to the USGS the new lavadome continues to grow with the rate of addition of lava to the dome from mid-May to mid-June remained at about 1.5 cubic meters (2 cubic yards) per second. The high point of the lava dome (the actively growing spine) on June 15 was 2,335 meters (7,660 feet), but it is currently lower than that owing to the recent large rock falls from the spine. They have also posted a new animation of the lavadome growth from June 16 to August 16, compiled from images taken by the remote camera at the location called the Sugarbowl.

The incandescent glow appears
Just for fun I have combined these images into a short animation - hopefully giving a sense of watching the incandescent glow appear as the night falls. After all, its interesting to see the details of that make up the diffuse brightness we see on the nightly Volcanocam images...

Zoom in on icy Enceladus
The Volcanocam's broke!
The US Forest Service Volcanocam has stopped transmitting images from the Johnson Ridge Observatory at Mount St Helens. The last image to be sent was from 18:35 on Friday night. The problem has occurred several times in the past and is presumably due to a communications failure between JRO and the web server. Unfortunately, the webmaster is away for two weeks starting last Wednesday, so it may be another week before its fixed...
There were a couple of larger tremors last night around 18:30 and 02:20 which are clearly visible on the St Helens - West webicorder trace and there was a M3.2 tremor at 18:10 on Friday night that was associated with a small plume of dust, and several other smaller tremors that night. However, until the communications problem is resolved, we won't know if this caused any heightened levels of activity during the night.
The USGS/CVO have just released a new movie of the growth/decay of the lavadome from the Sugarbowl camera - definitely worth a look!

My God, it's full of galaxies...
Looking at the new deep space image from the Hubble Space Telescope I was equally awestruck and felt like paraphrasing those wonderful words. Because apart from a dozen foreground stars, every bright spec in this image is a galaxy. Each with tens or hundreds of millions of stars of its own...

Mark August 12th in your diary for the Perseid Meteor shower
And if the weather is bad, you can always listen to the meteors on this link to a meteor radar station in Roswell, New Mexico.
