PAOPS (Prenoon Auroral Oval Poleward Shift): A Novel Prenoon‐Postnoon Auroral Asymmetry Phenomenon Revealed by Simultaneous Interhemispheric Observations

Abstract Previous studies indicate that specific polar cap auroral forms frequently occur in the postnoon in summer due to the influence of the interplanetary magnetic field (IMF) By component. However, regardless of the season and IMF conditions, similar auroral forms rarely occur in the prenoon. T...
