摘要：
We report two-dimensional, low-frequency radio observations of the angular broadening of the Crab Nebula (Taurus A) due to a coronal mass ejection (CME), at a distance of similar to 41 R-. from the Sun. The estimated electron density in the CME is about 50 times greater than that of the ambient corona at that location. The calculated mass agrees approximately with that reported earlier for similar events at large distances from the Sun.
