GR translation: sunfishing in the clouds

[Mike Jing]

After much deliberation, and further help from Jochen, I have decided
that "fishing for the sun" would be the best interpretation. Here the
balloons would be the bait on a line, and the sun would be the fish.
It does make sense.

"Sunfishing" as applied to horses is indeed a bit too obscure.  And
"verbing" sunfish just doesn't quite feel right to me in this
sentence.  In any case, something has to give, and the lose of these
secondary meanings seems unavoidable.

Again, thanks to everyone who cared enough to help.
