  We study the action of G = SL(2,R) on its type space S_G(R) where R denotes
the field of real numbers. We identify a minimal closed G-flow I, and an
idempotent r of I (with the respect to the Ellis semigroup structure * on I).
We show that the group (r*I,*) has 2 elements, yielding a negative answer to a
question of Newelski.
