Abstract

We show that within distances from the Sun's surface less than the height of a streamer helmet, each of two neighboring rays of the streamer belt, as they approach the solar surface, bends around the helmet on either side of it. Also, a minimum angular diameter of the rays of d≈2°–3° remains virtually constant within R=1.2–6.0 R ⊙. A density inhomogeneity (`blob') can be produced above the helmet top visible to at least R≈6 R ⊙. In this case the initial velocity of the `blob' increases with solar distance from where it is generated to something like the velocity of the bulk solar wind with which the `blob' is carried away.
