Magnetospheric Physics: Auroral Phenomena (2407)

Scientific paper

We observed an interesting auroral event at Poker Flat Research Range (PFRR, MLAT ~65.5°) using an all-sky imaging system. This aurora, which appeared in the evening (16-19 MLT) during a geomagnetically quiet period, maintained its patch structure and position for more than 40 minutes. These patches were distinct in OI 557.7-nm and N2 + 427.8-nm emissions. At this time, PFRR was located at a lower latitude region than the auroral oval. An extended plasmasphere was observed a few hours beforehand with the Akebono satellite in the afternoon sector. This evidence suggests that the particles causing this aurora precipitate from the extended duskside plasmasphere. We believe that the imaging observation from the ground using our technique is an effective method for investigating dynamics around the plasmapause, a still partially-unexplored region of space.
