NO! He is saluting his beloved Star.It’s an ancient custom used by old astronomers to see if our Sun is coronal or not.

Is Philippe really making a salutation to his experiment ?

But if it’s a real retirement, it could be :

Good-bye, the Sun

Should the time of your retirement be as long as 0,00000001 of the Sun’s life !

For us, it’s: good-bye, Philippeand thank you!
