What you see if you follow that link is still pretty basic, and does not run 24 hours (nor will it ever, we are a piggyback instrument dependent on LOFAR being in a specific observing mode). But right now there are some neat solar flares going if you watch a few minutes, so thought you would be keen to see it.
To explain, image in top left is the lag in the live image. Image in lower left is the correlation matrix of the raw voltages on the various antennas (to see if there are any antenna-specific problems). Top right is channel power over time- right now there are a lot of vertical lines that correspond with solar flares. And lower right is the exciting one, which is a live view of the radio sky right now in the Netherlands. The brighter stuff is labeled (Cassiopeia A is a supernova remnant for example), and the thing varying in brightness a lot right now at the bottom half of the image is the sun, thanks to an almost Jupiter sized sunspot.
Note, we don't run nonstop, so if it's a static image check back later.
