摘要:

Interplanetary magnetic field measurements made as NEAR approached Earth in December 1997 have allowed us to compare a magnetic cloud like event seen by the NEAR and WIND spacecraft. The magnetic cloud seen by WIND and NEAR has temporal signatures both in magnitude and direction that indicate a similar geometry and orientation. The magnetic helicity of the cloud structure seen at NEAR is the same as at WIND. The magnitude of the field in the cloud event is consistently lower at NEAR than at WIND as expected for radial convection plus expansion. We model the field of this cloud structure at each spacecraft, obtain fits to the cloud axis as well as rates of expansion, and find that the predicted spacecraft separation distance is consistent with observations. ©1999 American Institute of Physics.
