The sounding rocket measurements in the mid-latitude ionosphere suggest that the electron temperature occasionally increases at 100-110 km altitudes during daytime in winter. Detailed study indicates that such a temperature increase is closely related to the existence of the Sq current focus, because the temperature increase becomes significant when the measurement is made near the center of the Sq focus. In order to elucidate a mechanism to cause the electron temperature increase, the sounding rocket experiment was conducted in Uchinoura Space Center in Japan on January 16,2007. The rocket was launched at 11:20 JST after identifying that the Sq current was approaching to the planned rocket trajectory. The rocket certainly observed the local increase of the electron temperature at the altitude of 97-101 km. We present a preliminary analysis of the data such as the electron temperature, density, and its perturbation obtained during this campaign.
