One of my favorite web sites is
http://www.phys.unm.edu/~lwa/lwatv.html
It's a real-time map of  the entire radio sky at 38 MHz, from the "Long 
wavelength array"  (LWA) radio telescope in New Mexico.  The telescope 
consists of 256 dipoles spread out over more than 100 meters, giving a 
radio beamwidth of just a couple of degrees.

They make a movie of the previous 24 hours of observations, speeded up a 
hundred or more times.  This movie:
http://lwalab.phys.unm.edu/lwatv/59357.mov
shows yesterday's observations.  It shows the Galactic plane (i.e. the 
Milky Way) as well as the  Sun just before sunset.  Usually the sun is 
relatively weak at this frequency and barely visible on the plot, but in 
the first couple of minutes of this movie, as the Sun is setting it 
shows the Sun flaring up and sometimes dominating the entire sky 
emission, occasionally overloading the radio telescope.

     Cheers,
