AB: The auroral ionosphere were usually observed with incoherent scatter radar (ISR) or in situ measurement along the path of a spacecraft, which provided ionospheric information in a partial region. Due to the success of the FORMOSAT-3/COSMIC satellites mission since April 2006, global ionospheric structure can be monitored with the GPS radio occultation technique, especially in high latitude due to denser data distribution, and ionospheric radiance can be also observed with the space-borne tiny ionospheric photometer (TIP). We use the electron density profiles retrieved from COSMIC GPS occultation experiment and ionospheric radiance from COSMIC TIP, to display variations of the ionospheric auroral oval in the northern hemisphere, January 2007. The boundaries of the auroral oval are also discussed.
