An examination of high-resolution Mariner 10 magnetic measurements in the vicinity of the Mercury magnetopause for the three available crossings at high resolution reveals the signatures of what have been called flu transfer events (FTE). These events occur both in the magnetosheath and in the magnetosphere. They last about 1 s and hence have a dimension of about 400 km, or about 5% of the width of the Mercury magnetosphere. This relative dimension is similar to that observed at earth, but the repetition rate is about an order of magnitude faster at Mercury. The net amount of flux transfer is much less than that at the earth. We estimate that less than 1% of the available solar wind potential drop is applied by FTE's to the magnetosphere of Mercury. Evidence for ''steady state'' reconnection is also observed which may apply a potential drop from 5 to 25 kV across the Mercury magnetopause. The magnepause itself appears to be about 500 km thick. The shape of the magnetopause at the crossing locations can be approximated with a simple rotationally symmetric conic section with its focus at the center of the planet and an eccentricity of 0.8.
