英文摘要 | A new type of polar cap aurora, dawn-dusk aligned polar cap aurora (DDAPCA), was detected during the exceptionally intense January 21, 2005 substorm (AE(max)=3504 nT). The DDAPCA was located at very high latitude (> 85 degrees MLAT) in the polar cap region. As the interplanetary magnetic field (IMF) GSM By component rotated from a positive to a negative value, the DDAPCA tilt angle relative to the dawn-dusk direction rotated anticlockwise and reached similar to 45 degrees. It is speculated that the DDAPCA arises from the formation of an X-line in the distant (> 80R(E)) tail due to polar cap magnetic field reconnection under unusually high solar wind compression conditions.
