one. According to the King's data book the solar wind also rather stable in all parameters; for example, V gw changed within 360- 380 km/s range. 3. Observations within the plasma sheet Fig.3 shows some spacecraft trajectory information, whereas Fig.4 and 5 contain a summary of the main plasma sheet parameters measured by ISEE-1 in the dawn-side part of PS on Feb.19-20, 1978. In addition, Fig.3 includes the trajectory of ISEE-1 during one more SMC-like period (04— 15 UT on April 24, 1980, A E ~ 2 0 0 nT), when the satellite traversed PS from its southern part towards the northern lobe in the duskside sector of the magnetotail. Basing on this information (both shown and not displayed in Fig.4 and 5), as well as on the results of the previous studies, we may summar ize here the main features of SMC-like periods: ЗИ. The magnetic field within PS does not display drastical changes, the significant В ~ 5 nT is sustained within PS at ISEE-1 distance (see also Pytte et al., 1978, Sergeev, 1977). 5.2 The thickness of PS is about 8-9 Kg in the center (Apr. 24, 1980) and is slightly greater towards the flanks, where even p - 1 conditions are met at Z ~ 4 Rj. (Fig.4, bottom). 3»?. Both the proton and electron densities and temperatures are quite stable and change slightly across the main body of PS (except for the outer boundary part of PS). The temperatures are higher as compared to the quiet-time PS: Ё ~ 5...6 keV, Ee~ 1 keV, n ~ 0.1...0.2 cm~^. In this case of the davnside pass of ISEE-1 the oxygen contribution to the ion parameters was negligibly small according to the data of Lockheed mass-spectrometric experiment. 3.4.Intense fluxes of energetic protons and electrons are sustained within PS at 20 Rg (Fig.5, see also Pytte et al., 1978). 3.5. Plasma flows are very slow (few tens km/s) within РБ (under Р^£, Pg) and directed (in average) both towards the Earth (Vx > 0 ) and towards the flank (Vy<£ 0) during two firet SMC inter vals (17-23 UT and 01-06 UT). • 3.6. In a 3harp contrast, the plasma flows are significant (at times) and are directed earthward during the third SMC-like Interval (08— 12 UT on Feb.20), when both the temperature and den sity also undergo significant variations. Here the satellite was clearly in the outer boundary part of PS, since P g » P^. We inter- 16
