An equatorial coronal hole at solar minimum

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