LASCO/C2 images from (a) 22 May, (b) 26 May, and (c) 1 June 1997.
The white line shows the equator and the direction to Ulysses,
10 degrees north of the equator.  The streamer belt was confined to
the equator during this entire interval, but changed appearance.
There was a bright, isolated streamer during 21-25 May and also from
29 May to 1 June.  During 26-28 May the equatorial streamer broadened
into a fan (or "forest") made up of several rays without an obvious
isolated streamer.  This forest is interpreted as a result of viewing
the streamer belt more from the side than from along the belt.

The quadrature date was 26 May, when Ulysses lay exactly off the limb
of the Sun with respect to SOHO.  The direction to Ulysses was just
inside the boundary of the bright streamer at 5 solar radii.
Solar minimum conditions existed throughout the observations.
