NO! He is saluting his beloved Star. Its 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 its a real retirement, it could be : Good-bye, the Sun Should the time of your retirement be as long as 0,00000001 of the Suns life ! For us, its: good-bye, Philippe and thank you!
