The white-light corona calibrated data with processing level L1 from the LASCO-C2/SOHO instrument, and data from the Wind spacecraft with one-hour and one-minute time resolution on quasi-stationary slow (v between 300-450 km/s at the Earth’s orbit) the Solar Wind (SW) parameters in the absence of sporadic SW streams are examined. Within distances from the Sun’s center less than R in the range of 20-30 Rs, (Rs, the solar radius), slow wind is known as the streamer belt, and at larger distances it is called the He-liospheric Plasma Sheet (HPS). It is shown that the streamer belt comprises a sequence of pairs of rays. In general, ray brightnesses in each pair can differ, and the magnetic field is oppositely directed in them. The neutral line of the radial magnetic field of the Sun runs along the belt between the rays of each of the pairs. The area in which the streamer belt intersects the ecliptic plane and which lies at the central meridian, will be recorded at the earth’s orbit with a time delay of 5-6 days, in the form of one or several peaks with Nmax> 10cm-3. Furthermore, the simplest density profile of the portion of the HCS has the form of two peaks of a different or identical amplitude . The such a profile is observed in cases where the angle of intersection of the streamer belt with the ecliptic plane near the Sun is sufficiently large, i.e. close to 90°. The two-ray structure of the cross-section of the streamer-belt moves from the Sun to the Earth, it retains not only the angular size of the peaks but also the relative density variations, and the position of the neutral line (sector boundary) in between. At the Earth’s orbit the ray structure of the streamer belt provides the source for sharp (i.e. with steep fronts of a duration of a few minutes or shorter) solar wind plasma density peaks (of a duration of several hours) with maximum values Nmax> 10cm-3.
