The large transequatorial coronal hole that was observed in the solar corona at the end of August 1996 is presented . It consists of a north polar coronal hole called the ' elephant 's trunk or tusk ' . The observations of this coronal hole were carried out with the coronal diagnostic spectrometer onboard the Solar and Heliospheric Observatory ( SOHO ) . The magnetic field associated with the equatorial coronal hole is strongly connected to that of the active region at its base , resulting in the two features rotating at almost the same rate .
