  1. N S Transequatorial Loops and CMEs Coronal Mass Ejections (CMEs) may be a vital part of renewing the Sun’s 11-year activity cycle by taking away some of the East-West (toroidal) portion of its magnetic field. Some loops in the Sun’s outer atmosphere (corona) cross the solar equator (top). These transequatorial loops (TLs) can have footpoints separated by as much as 75°, and can be up to half a solar diameter in length! Evidence from the Yohkoh X-ray mission (top) shows that TLs which are skewed east-to-west (left) are more likely to be involved in CMEs. So it looks like they do carry away toroidal magnetic field! A difference in solar longitude is the most important criterion for the TL to produce a CME.
