Nice article but... it was published a little bit too late, don't you think???
Hayabusa data already making obsolete most of these ground based...!

Sure but the paper was released only two days ago.

Is what I'm saying, SRF!
They waited more than one year to prepare and send this article (it was received on Aug,29); I understand that time is needed to elaborate data and make correct interpretation but I am disappointed because, for sure, a slightly anticipated publication would be strongly reccomandable in this case!
