(a) GTL data obtained on a skimming orbit nearly along the magnetopause on February 9–10, 1999. GTL was always in the magnetosphere except for a short time interval at 12:31. Fairly regular oscillations of plasma flow with amplitudes more than 50 km/s were observed in the morning sector. In contrast, wave forms were less regular in the afternoon sector. A remarkable contrast between the morning and afternoon sides is notable in normalized amplitude and plasma β. (b) Scattered plots of quantities estimated from the diamagnetic relation versus observed variations of the field magnitude, dBT.
