The rainbow has landed

Houston, Grundsviken Base here, The rainbow has landed.
( Inspired by Neil Armstrong's famus words during the Apollo 11 misson , July 20 1969:
" The Eagle has landed " )
The view from my yard the afternoon before last, over Lake Kall and the church in Kall.
Never seen before in my 60+ years here. I also have another photo, where you can see the upper arch.
Just wondering if this could be something special........
Thank You, and take care for now !
