spaceweb@oulu.fi - last update: 25 November 1998, 1130 UT (RR) . During increased geomagnetic activity , the quiet auroral arcs become more active, producing forms like spirals, curls and folds (e.g., Hallinan and Davis, 1970; Davis and Hallinan, 1976). Localized upward field-aligned currents (Rostoker, 1987; Bythrow and Potemra, 1987) are associated with these structures. ... 92 , 8691-8699, 1987. ... Hallinan, T. J., and T. N.

... P1724 was monitored from MTSB on 17 nights over a six week period. ... Three field stars were used for comparison (see Figure 3 ). ... The preferred frequency is 1.18 rotations per day (a 0.85 day long period), but the power at this peak is not particularly stronger than the three other strong peaks. However, the 1.21 day period (0.826 rotations per day) is excluded by the nightly trend analysis. In this case, the trend of the data is opposite to the direction of the fit (see Figure 5 ). ...
