Halo CME on 20031028 - SOHO/LASCO C3 Data

COMMENTS: It looks to me that the Bz in the magnetic cloud will be positive (northward directed). If so, no significant storm. However, the absolute magnitude of the Bz should be really high! I'd say we are looking at at least 50nT or, quite possibly, more then that! Should I be wrong and the Bz turns negative, i.e. southward, we can get a really severe storm with the Dst of about -400nT or more! Now we have to leave, because of the SoCal fires, there is voluntary evacuation in Big Bear, so have to get moving. Is there a connection between the fire activity and solar activity these days? :)

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
