| Popis: |
A low-latitude aurora was observed at Rikubetsu (L=1.6), Japan during the main phase of the moderate magnetic storm of September 13,1993. Although the sky at Rikubetsu was covered by thick clouds on this day, the aurora was identified as a significant enhancement in the 6300-A emission. It is likely that this aurora occurred in association with the expansion onset of an intense magnetospheric substorm, lasting approximately 1 hour. A notable point is that this aurora was observed during the moderate magnetic storm, indicating that low-latitude auroras are not always associated with intense magnetic storms. It is argued that the so-called Stable Auroral Red (SAR) arc and the substorm-associated low-latitude aurora should be distinguished in their production mechanisms, since the latter aurora must be accounted for in terms of substorm processes. |
