摘要: [1] In this study we present ultraviolet and infrared auroral data from 26 July 1998, show the presence of transient polar spots observed throughout postdusk to predawn local time sector. The dawn spots, which are features in sector poleward main emission, were previously associated with inward moving flow resulting tail reconnection. suggest that nightside close midnight sector, related flow, like spots. We base our conclusions on near‐simultaneous set Hubble Space Telescope (HST) Galileo observations during HST a spot magnetically mapped location an detected by same day. derive emitted power magnetic field measurements along plasma bubble, it matches inferred HST. Additionally, reports for first bright infrared, could be possible signature appears within interval 30 min ultraviolet, emission ionosphere planetward reconnection x line equatorial plane. Finally, work demonstrates ionospheric signatures bursts released instantaneously over wide
