Closing Remarks by ER Priest
In recent past huge advances from
Yohkoh SoHO
TRACE
(born Sept 23, 06)
Clearly, producing next great advances in our subject
So what learnt so far ?What expect in future ?

Future ?
3. Will learn much more about fundamentals of
-- nature photospheric B - how formed, evolves, disappears -- cause spicules -- origin flares, cme’s -- nature prominences -- cause coronal heating -- ………
1. Just a beginning !
Hinode is Gold Mine -- wealth of discoveries
2. Especially when combine instruments
-- encourage collaborations, young people
