Comparisons of temporal variations of auroral emissions (1 s data used) between 427.8 nm (black line) and 557.7 nm, 630 nm, 777.4 nm, 844.6 nm from top to bottom are presented for 12 min between 02:12:00 and 02:24:00 UT on January 23, 2018. The emission intensity values of 557. 7 nm, 630 nm, 777.4 nm, and 844.6 nm are multiplied by 0.1, 1, 1, and 1, respectively, and shown in red solid lines
