| Description | Digital data of auroral keograms taken by the white-light all-sky imager (made by Watec) at Tjautjas, Sweden. This observation started in September, 2017. The original images were taken at higher temporal resolution than one second. The north-south and east-west keograms are time-series of north-south and east-west cuts of auroral images and are used to see the north-south and east-west motions of aurora, respectively. |
