Halo CME on 20031102 - SOHO/LASCO C3 Data

COMMENTS: Because the CME originated close to the solar limb it is not possible to estimate the direction of the magnetic field at the front edge. Estimates below are the upper bound for the Bz and the Dst and they were made assuming that the magnetic field will be southwardly directed. The limb CMEs tend to be less geoeffective then the disk CMEs, however due to the hight speed it still can cause a moderate storm.

1Numbers in red are estimates. Numbers in parenthesis (if any) are actual measured values
*These estimates should be compared to the observed 1 hour averaged ACE and Dst values

  • Real Time Dst from World Data Center for Geomagnetism, Kyoto
  • Predicted Dst from Nonlinear Dynamics and Space Physics group
  • Real Time ACE data
