Thanks Graham, That does help and I think I'll pin it and have a look at it from time to time.

What I haven't got my head round yet is the Solar Wind. Is it actually wind or is it in fact just a stream of photons or some such.

A 600 km/s is rather off the Beaufort Scale so I suspect it's not wind as we know it.

So question, what is Solar Wind ? thinking
