[PEM07-15] Statistical feature of Omega band aurora observed by THEMIS all-sky imager network
Keywords:aurora, omega band aurora, magnetosphere, ionosphere, magnetosphere-ionosphere coupling, polar region
In this study we examine statistical features for the following parameters when Omega aurora observed; 1) magnetic local time (MLT), 2) seasonal variations, 3) annual variations, 4) life time, 5) drift speed, 6) scale size, 7) Kp and AE index dependence, 8) solar wind speed and pressure, 9) IMF By and Bz dependence. Then we will discuss their signature.
