Mount St Helens Volcanocam goes High Def!
The difference between the two images is stunning, below is a early morning shot taken at roughly the same time by the two cameras. The first is the "old" camera, the second the new higher def camera.
The night time performance is also much improved, although there is still some significant noise associated with the new camera (see image below) - which may be due to the high temperature it appears to be operating at. Notice in the upper legend on the new camera it provides details of the temperature of the camera and the outside air. The outside air temperature at 4:26am was a cool 13.5 deg C (56.3F), while the camera temp was a quite toasty 33.5 deg C (92.3F)! If there was any way to cool the camera down it would almost certainly improve the noise levels.
Even with these noise levels we can see some signs of good night time sensitivity from this camera. By removing the noise and combining the brightest pixels from the five images taken from 01:36 to 03:56 (the new camera only seems to be updating every half hour at present), we can see a bright object passing over Mount St Helens. I'm not sure exactly what it is, possibly a bright star or a planet (it's not the moon as it set at 2:47am), but it clearly demonstrates the greater resolution and sensitivity of the new camera.
With the addition of this new camera watching Mount St Helens, all we need now is the continuing extrusion of lava to move back into view of the cameras, and we can look forward to some spectacular views of the night-time activity at MSH!
