AB: We will present multi-spacecraft observations by STEREO A and B and WIND of a magnetic cloud in the interplanetary space on May 21-23, 2007. At that time the angular separation between STEREO A and B was nearly 10 degrees. The differences in the observed magnetic field signatures at the locations of the spacecrafts suggest that they crossed the different parts of the magnetic cloud. STEREO B observed a very clear rotation of the magnetic field direction and presumably crossed the cloud close to the center whereas STEREO A likely traversed the leg of the magnetic cloud. Although the magnetic field maximum within this cloud was ~17 nT it did not produce significant geomagnetic response since the Z-component of the magnetic field was orientated northward. We will analyze the structure of the magnetic cloud at each spacecraft in order to deduce its larger-scale structure and orientation. In addition, we will study the solar source region of the magnetic cloud as well as the coronagraph and radio wave observations.
