EM waves were detected from L* = 4 to 9 from 09 to 12 MLT with a decrease in the afternoon sector (12 to 15 MLT). Some of the chorus was clearly related to generation by substorm injected similar to 5 to 100 keV electrons drifting from the midnight sector to the local noon sector. However, dayside chorus also showed two solar wind ram pressure dependences: increased (above average) pressures and unusually low pressures. Possible chorus generation mechanisms are discussed. Chorus detected by Polar away from the magnetic equator generation region (similar to 25 degrees to 55 degrees magnetic latitude) was substantially different than chorus detected in previous studies within the similar to 0 degrees to 10 degrees generation region.
