Help – roof windows left open in rain

Moin, last night my car parked with open skylight ?? App did not hit unfortunately … now it rained since this morning 0700 clock and at 1030 binnichvzum car. Until then everything was wet and out of the roof sky (covering the mirror – see photo) came later also water. What do you do? I drove around now about 3h at 28 degrees so that everything dries. Does someone like me can open the cover so that air gets there?
