SEC (May 27-29) had expected a g/m storm (Ap=25-20) on May 29
and 30 while SSM (May 27) and Meudon (May 27) had not.
However Meudon (May 28) had changed its mind and had expected a
g/m storm (Ap=30) on May 30.
There was no storm on May 29 and 30.
So SSM, SEC, and Meudon take 2, 0, and 1 respectively.
The current May's score is 10 : 8.5 : 5.5.
