Venus Transit in Progress ! Clouded out ? Get a view courtesy of NASA

Its after midnight over here in the UK and there will be cloud 5-6 am so no chance of seeing the transit for me. I popped over to the NASA Live stream here http://sunearthday.nasa.gov/webcasts/nasaedge/ for a view and was surprised to see that the images are actually being broadcast via views from readily available amateur solar telescopes. Andy Lunt of Lunt Solar Systems http://www.luntsolarsystems.com/  was explaining the different wavelengths of light that we can view the transit in including Hydrogen Alpha (red), Calcium K (purple blue) and White Light (how we would see it in natural light if it wasn’t so bright – NOTE do not look at the sun directly ! ).  I took a set of screenshots from the live feed so that you can see what is going on. It gives you a great impression of the size of the planet Venus relative to the size of the Sun. Earth would typically fit into one of those larger sunspots you can see to the left.
